Visually I’m working on a new landing page for phrasing. It’s almost done, just need to record a few videos: https://phrasing.app/next

Behind the scenes I’m rebuilding the sync engine to properly support offline mode. Trying to get to instant opens for the app (and of course work offline). It’s probably my 5th sync engine. It’s been really fun to see how much easier, faster, better, etc each new iteration is.

(And the project at large is https://phrasing.app - a language learning app for polyglots. It’s like anki but designed to be enjoyed)

I'm working to figure out new auxetic geometries for 3D lattices. The arrowhead is cool and simple, and gyroids are very effective, but I'm trying to discover if there's something simple, printable, and maximally effective. Tough problem. There's no general theory for auxetic lattices, so it's a matter of reasoning from the desired mechanism to find patterns that fit, almost like alchemical trial-and-error.

Myself, mostly. Trying to wrestle with realizing how much time I've not been spending on my supposedly main project[1] and questioning whether it's really worth doing.

> Any new ideas that you're thinking about?

Way too many. Writing todo lists is part of working on myself.

[1]: PAPER, a pure-Python ~(pip/pipx replacement), from scratch with an emphasis on simplicity and elegance. https://github.com/zahlman/paper . There's more locally that I haven't pushed, including factoring some stuff out into a separate project and planning more of the same. But yeah.

The same tech stack is pretty easily adaptable to openclaw tracking. If anybody would like to try, DM

Also looking into AI based security tools for monitoring security of DoneThat. Thinking of using zeropath would love to hear if people tried them / have other suggestions

I'm building a free alternative to SimpleCitizen (YC S16).

It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.

So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.

https://fillvisa.com/demo/

I found out simplecitizen offers a DIY plan for $529 (https://www.simplecitizen.com/pricing/)

So, a free (and local-only) version might be a good alternative

Working on new code review tooling specifically for reviewing your own branches/commits when you use an "AI Agent" to assist with writing code. It seems all of the tools people are building in this space attempt to automate away the review, but I want better tools for reviewing (and tracking tech debt) in the code I just generated locally. Will publish here soon

Lots of work left to do, but happy to have a working version up. It's an interactive map that currently shows all the routes and stops for SF Muni, BART, Caltrain, samTrans, and VTA. There are many more agencies (official and unofficial) in the bay, so I'll be adding those throughout the next few days as I sort out the data.

Finding the data and cleaning/normalizing it is a real pain, so if anyone knows a good place to find them (and normalize them), please do share

A tool for creating CSS color palettes for web UIs that pass WCAG accessibility standards for color contrast:

https://www.inclusivecolors.com/

Unlike most tools based around autogenerating colors, this is more of an editor that lets you fully customise all the tint/shades to your liking and with a focus on accessibility. This is important when you've got existing brand colors to include and want to find accessible color combinations that work together.

Would love feedback in general and especially from designers/devs who have different needs in how they go about creating branded palettes!

I've got replicas now working with DML proxy. This essentially means I can now have a cluster of primaries, and then spin up replicas on demand and nodes talking to local host will never see their mutation work pretty transparently from readonly-replicas. While PoC works now the snapshot restore is extremely inefficient IMO yet.

After 15+ years in web development — now diving into game development with Three.js / React Three Fiber (R3F). Keeping AI usage minimal where possible, but it’s been invaluable for complex geometry and math-heavy problems.

Game idea: DroneCraft is a third-person drone exploration game where players scout the world for parts, craft powerful upgrades, and trade strategically to evolve their build.

Whats coming: Core mechanics are up and running. First playable version planned within a month, alongside open-sourcing the full codebase.

I'm working on a chrome extension that helps answering "Cover letter / Tell us about the time when... / Why do you want to work at..." questions in job application forms.

You can bookmark a job description (it will be parsed), then paste a question and it generates an answer based on your resume, the job description, and your previously given answers for similar questions in other applications. The generated answer can be refined through a follow-up chat and exported as a PDF. It also works as a simple job application tracker.

Saves me tons of time and effort every day!

Finally trying out Godot on a real project.

I've been pretty bummer out by Rainbow 6 Siege X announcing they will never support Linux due to a lack of kernel-level anti-cheat support. While I can use NVIDIA shield to play from my Windows pc, id rather play something natively with friends (for context, we usually play 3v3's for funsies.

My goal is not to make an exact clone, but to make a smaller map version for 3v3 that is a bit more quick paced.

For context, it's a bomb defusal game where the main goal is intel and gadgets. You need to make the other side waste their gadgets so it comes down to a gun v gun fight.

Right now there's an MVP available, which focuses on

- building an independent line of communication with your audience

- predictive, just in time notifications through push or email delivered when we predict that specific viewer has the time to view videos on YouTube, ensuring you stay on top of their notification stack and don't disappear amongst a flood of notifications.

I'm thinking all the time about what the "best" way of using local AI agents like Claude / Codex / Gemini is. I'm trying to figure out the best UI/UX. There's so so so much that hasn't been explored yet.

Mainly I'm working on a task dispatch dashboard called Prompter Hawk that is designed to be the best UI for task management with agents. If you've been trying to parallelize by running multiple claude code terminals or codex terminals at once, this tool replaces those terminals and fits them all into one view with an AI task tracking board. It sounds more complicated than it is. It's a harness for Claude / Gemini / GPT models with a GUI that speeds up all your workflows. Rather than using sustained chat mode, all Prompter Hawk tasks are fire-and-forget. You just give the task description and come back when it's done. Parallelism first.

Some example highlight features:

-One dashboard view that shows all your parallel sessions and which tasks each agent has in progress and in their queue. Also shows recently completed tasks and outputs. This is my attempt at the ideal "pilot's cockpit view" for agentic development.

-Tasks are well tracked by the manager: see their status, file changes, and git commits. One click task retry. Get breakdowns on cost per run. Tasks can be set to automatically recur on a given schedule. Everything goes into a persistent local DB so you can easily pull up task data from months ago. Far far better user experience than trying to pull up old chat histories IMO.

-Timeline view and analytics views that give you hard stats on your velocity and how effectively your agents are using and updating your codebase. See unique stats like which of your files your agents read the most and how many daily LOC and commit changes you're doing. See how well you're parallelizing workloads at a simple glance.

-Automatic system diagram generation

-Task suggestion feature. If your agents are idle, they can draft tentative tasks to carry out next, based on the project history and your goals. This makes keeping multiple agents spinning actually much easier than you'd think. You don't need to be a multitasking context-switching god to do this.

I haven't shared it much (not even a Show HN) because the landing page isn't converting well at all yet, though I have some reddit ads doing well. I've had a bunch of free users sign up and a handful of paying users too. Looking for users or just feedback on anything! Sorry for wall of text.

This weekend I've been going through a bunch of stuff with A2A, building little samples and just getting my head around it. Threw together this repo[1] with a bunch of the stuff I'm doing, if anybody else is interested.

Also, watching a bunch of videos and reading docs on OpenClaw. I had thought I'd do an install of it sometime this weekend, but I don't know if I'll get to that at this point or not.

And lastly, messing with Spring AI[2]. I wanted to get a local build of that going so I can dig into the bowels of it and hack on it a bit. So I got that repo cloned and ran a quick build, and now I plan to start exploring the codebase.

👤 RickHull
I'm working on a poker (NLHE) trainer app that includes a web poker room for multiplayer, with bots available and fake chips. Using Event Sourcing with some CQRS in Elixir and Phoenix. The player view is a projection of House Events, suitable for hand history, for feeding to solvers or LLMs for real time advice or post hoc analysis.

The idea is to get tons of reps in, across varied situations, with excellent advice to build good intuitions and decision making abilities. Or to stop making bad or terrible decisions. Or just play poker for free.

I'd like to monetize with at least the hand history format open sourced. Ping me if you would like to get involved with GTM and the revenue side of things.

I'm also working on a new strength gains-tracking app that is a lot more intuitive, motivating and friend first. I've been using it with some friends for the last 10 weeks and everyone making is consistent gains. It is my first full PWA, vanillaJs, backend is Lucee & MySQL. Works great on iOS and Android, no one has any complaints. The web stack has come a long way I am probably not going to do a native mobile app for a while. I'll probably make it public in a couple weeks.

I'm currently unemployed and I started using Codex a couple of weeks ago so lot's of simultaneous projects, some stalled

Pre-codex:

Local card game: there's a very specific card game played in my country, there's online game rooms, but I want to get something like lichess.org or chess.com scale, oriented towards competitive play, with ELO (instead of social aspects), ideally I would get thousands of users and use it as a portfolio piece while making it open source.

cafetren.com.ar: Screen product for coffee shops near train stations with real time train data.

Post-codex:

SilverLetterai.com: Retook a project for an autonomous sales LLM assistant, building a semi-fake store to showcase the product (I can fulfill orders if they come by dropshipping), but I also have a friend and family order which I should do after this. 2 or 3 years late to the party, but there's probably a lot of work in this space for years to come.

Retook Chess Engine development, got unstuck by letting the agent do the boring busywork, I wish I would have done it without, but I don't have the greatest work ethic, hopefully one day I will manually code it.

Finally, like everyone else, I'm not quite 100% content with the coding agents, so I'm trying to build my own. Yet another coding agent thingy. But tbf this is more for myself than as a product. If it gets released it's as-is do what you want with it.

I'm learning about "AI programming" by working on some toy problems, like an automated subtitle translator tool that can take both the existing English subtitles and a centre-weighted mono audio extracted from the video file and feed it to an AI.

My big takeaway lesson from this is that the APIs are clumsy, the frameworks are very rough, and we're still very definitely in the territory of having to roll your own bespoke solution for everything instead of the whole thing "just working". For example:

Large file uploads are very inconsistent between providers.

Automatic context caching isn't.

JSON schemas are a hint, not a constraint with some providers.

Some providers *cough*oogle*cough* don't support all JSON Schema constructs, so you can't safely use their API with arbitrary input types.

If you ask for a whole JSON document back, you'll get timeout errors.

If you stream your results, you have to handle reassembly and parsing yourself, the frameworks don't handle this scenario well yet.

You'd think a JSON list (JSONL) schema would be perfect for this scenario, but they're explicitly not supported by some providers!

You can tell an AI to translate the subtitles to language 'X', and it will.. most of the time. If you provide audio, it'll get confused and think that it is being asked to transcribe it! It'll return new English subtitles sometimes.

Speaking of failures, you also get refusals and other undocumented errors you'll only discover in production. If you're maintaining a history or sliding window of context, you have to carefully maintain snapshots so you can roll back and retry. With most APIs you don't even know if the error was a temporary or permanent condition, of if your retry loop is eating into your budget or not.

Context size management is extra fun now that none of the mainstream models provide their tokenizer to use offline. Sometimes the input will fit into the context, sometimes it won't. You have to back off and retry with various heuristics that are problem-specific.

Helping out with a freelance project I built 15 years ago. It didn’t end on the best of terms, but the relationship has since been repaired (and I’m much better at managing my time now)

It’s been fun to come back to, most of the code I wrote still drives the business (it’s just far outdated).

I was pretty early on in my career when I wrote it, so seeing my mistakes and all the potential areas to improve has been very interesting. It’s like buying back your old high school Camaro that you used to wrench on.

Microplastics are bad. People are concerned that there are microplastics in your balls! And that this could epigenetically affect downstream generations. I want to test that theory with a real human, not an animal model.

My plan: collect my own sperm samples over time and do whole DNA preps + basic body metrics. Sperm regenerates approximately every 10w, so planning time series over 10w. Next, inject myself to ~10x the average amount of microplastics, directly into the bloodstream. Continue with the sperm collection, DNA preps, and basic body metrics. Nanopore sequence, and see if there actually ARE any epigenetic changes. Eventually I'll go back down to baseline - are there any lasting changes?

Of course, this is an N=1 experiment, but rather than a metastudy I'm directly changing one variable, so I think it is valuable. We should have more people doing controlled experiments on themselves for the sake of all of society - and as a biologist, I actually have the capacity to design the experiments and scientifically interpret the results. In a way, it's part of civic duty :)

I'm working on publishing a big update to my open source .NET project, ShopifySharp. I recently finished a custom graphql query builder generator (written in some sloppy F#) which will be included in the next release, which means all of the types, queries and mutations in Shopify's graphql schema will have a matching fluent-style query builder in ShopifySharp.

Aiming to get that published in the next day or two, and then I plan on diving in on a complete rewrite of the book I wrote on building Shopify apps with .NET and C#. It's long overdue, the book still uses Shopify's deprecated rest API and some methods that aren't supported anymore, but I've been holding off on an update until I could rewrite it with the new fluent query builders in ShopifySharp.

Outside of my OSS stuff, I'm continuing working on my SaaS app, Stages (https://getstages.com) [¹], which has been paying my mortgage and bills. Customers have been asking for lots of features lately and I'm anxious to get a particular one finished (filtering orders and events before they come in and are saved to the app) soon. It's my biggest source of churn right now.

[¹] Elevator pitch: the app is like a pizza tracker for your orders that have a custom or long, drawn out production process. Your staff and customers can see exactly where an order is in the process without calling or emailing you. Shopify only for now but one of main dev goals is to move beyond Shopify.

RxJS vite plugin that operates in much the same way as react devtools and vite plugin, because I love rxjs but I cannot recommend it without that same calibur of tooling. Turns out you can take a lot of ideas from the react vite plugin and do a bunch of similar things.

Trying to parse, model the HMR process, and storing the data as flat as possible and doing it from relation design first, has been a pleasant process.

Im hoping it works for react devs easily, and then I guess I'll try to learn angular to see if that would not be helpful for them too.

I mostly want to help my old coworkers maintaining my old crazy code with a visual helper.

StoryStarling - Turn your story idea into a printed children's book

https://storystarling.com

Working on a platform where you describe a story concept and it becomes a real, illustrated picture book - professionally printed and shipped to your door.

The key difference from "personalized" book companies: this isn't template stories with a name swapped in. You bring an idea - maybe a book about a kid with a cochlear implant going to their first day of school, or a bilingual German-Turkish story about visiting grandma's village - and it generates a complete original narrative with consistent illustrations throughout.

You can upload reference photos so characters actually look like your child. Supports 30+ languages including bilingual editions on the same page.

Currently refining the showcase features and adding RTL language support.

Working on reproducible test runs to catch quality issues from LLM providers.

My main goal is not just a "the model made code, yay!" setup, but verifiable outputs that can show degradation as percentages.

i.e. have the model make something like a connect 4 engine, and then run it through a lot of tests to see how "valid" it's solution is. Then score that solution as NN/100% accurate. Then do many runs of the same test at a fixed interval.

I have ~10 tests like this so far, working on more.

I left my job as a PM a couple of years ago to start acquiring small e-commerce brands that sell on Amazon. I'm currently running those, and mid-acquisition on one.

Because they're relatively low-effort (Amazon is terrible for sellers in many ways but man do they provide an incredible amount of infrastructure), that leaves me plenty of time to play with AI, and it just so happens that the business serves as a giant, practical eval as new models come out.

I've been vibe coding apps for internal use and using Nano Banana for listing images and whitebox photos, and more recently I've started to lean on Claude Code heavily as an assistant. It's got API creds for my Amazon account, so I use it for everything from figuring out when I need to reorder to filling out spreadsheets for companies that safety test my product.

And of course I am writing a Substack that I must shamelessly self promote that goes into the practical use cases of AI in my business: https://theautomatedoperator.substack.com/

Finding work after a corporate restructure. Also migrating my workloads from VMs and strewn-about containers onto a Talos K8s node, so I can break the cycle of bespoke builds at home and get back to enjoying projects.

Speaking of projects, I’m roughing out a method of pulling cost data for common services (compute, storage, databases, etc) across the three major cloud providers and making recommendations as to where to put things for optimal cost; a key component of a “universal cloud” idea I’ve been kicking around since 2020 or so, where the base cloud services are abstracted away into commodities rather than bespoke products or locked-in vendors. The goal is to basically have something like Terraform that will transpose its code to the destination cloud chosen by the cost analyzer at execution, and eventually auto-migrate load as prices or needs change (e.g., a client churning early and shifting that reserved instance to another customer for a higher margin).

Write once, and trust the pricing model to deploy it where it makes the most fiscal sense. No more learning Azure/GCP/AWS for bog-standard workloads anymore.

I've been working on a tool to solve a problem I keep seeing at my day job when handling large-scale deployments and migrations. The “plan” is always scattered across internal docs, spreadsheets, and Slack threads. Coordinating work across multiple teams becomes messy fast

So I'm building Taskplan (https://taskplan.run) - it's like Ansible, but for people. Build a plan, assign tasks to people or teams, and get a real-time dashboard to track progress as the work happens.

I'd love feedback from anyone who deals with the same issues or works on ops-heavy projects.

I'm working on a (somewhat) realistic surfing game. Tired of arcade-style games, I decided to try my hand at something closer to the real sport, focusing on realistic breaking waves, speed generation and carving, rather than impossible air combos.

After one year of development, it's going better than I expected, so I'm considering building a demo to gather feedback and see if there's enough traction for working towards a Steam release.

Even if that's not the case though, it's been a blast learning about game dev in Unity/C#, as well as 3D modeling and animation in Blender!

building a few things currently

https://ultrasync.dev/ - this was built a few months ago but expanding to support team based features like centralized sharing and management of ADRs to enrich my coding agent's context, the ability to broadcast prompts to team members running the MCP server, and more. the core is open source and provides (i think) a novel approach to improving planning/exploration speed in coding agents, by building an LMDB and using Hyperscan (accelerated pattern matching) to build a lightweight lexical and semantic index for RRF search, all in a single MCP server that runs and indexes chat transcripts in the background, requiring zero prompting or "nudging" or additional setup.

https://mklogo.sh/?utm_source=hackernews - wanted to scratch a personal itch of having to repeat the same process to produce vectorized logos for my personal projects; generate decent quality logo in raster with various LLMs, attempt to vectorize via claude code and vtracer or other tooling, continue to iterate and tweak until various edge cases that result in corrupted or artifact ridden vector images are gone, or give up and try a new design, and then manually try to scale and apply transformations based on the use case (mobile icon, favicon, app icon, header logo, github org logo, etc.). this does that, vectorizes, gives you a branding package as a zip file, and lets you preview the assets in shadcn components so you get a real feel for how they'll look in prod.

I’ve been working on a developer-facing sandbox for AI agents that focuses on budgeting and cost control, not payments.

In multi-agent setups, we kept running into issues where agents either hoarded resources or exhausted shared budgets unpredictably. So we built a control layer where agents operate using virtual credits, can temporarily rebalance budgets or split shared API costs, but everything stays under explicit human-defined limits with full audit logs and kill switches.

It’s intentionally not real money and not a financial product — more like infrastructure for coordinating agent spend safely. Mostly exploring how much autonomy you can give agents before cost becomes the real bottleneck.

👤 RickS
An alternative client for Bambu 3D printers that plays nicely with network sandboxing and multiple printers. It's great.

Bambu's printers are functionally best-in-class, but intrusive and proprietary in their approach to software. Their first-time setup "requires" linking to a cloud account or using a bambu app via QR code, and they've been known to disable functionality in updates, making a device-managed "LAN-only" mode unsafe to trust. Their apps also just suck. Camera feed is janky and LAN-only sync often requires knowing an access code, serial, IP, and then it fails most of the time anyway, silently, without saving values to retry. And that's before you start doing things like a custom VLAN/SSID to properly wall them off, at which point you can ping them from terminal but the apps break completely.

Anyway, turns out that at least on A1 and P1S, there's enough functionality available through traditional means to skip the apps entirely. The handshake works fine across VLANs and utils like print status, file upload, and auto-start are available. Even the camera is reliable when pulled as a series of still images.

I had opus vibe out a replacement front end that gives me a simple upload and monitor UI for my A1, and it just kept hitting stretch goals. I added support for multiple printers so you can see them stacked on a single page and manage all of them from one place. And it even works on just-unboxed models that have never been through the official setup. SSID info on the SD card, it joins the network, immediately accessible via IP. Zero association/contact with any cloud or app, fully sandboxed/offline. Wrapped in a lil python launcher so I can run it from the dock instead of in the browser (just my preference).

Will probably open source it soon.

IMO this kind of thing is the answer to "what do you have to show for your LLM use". Cost was about $65 because I was using opus 4.6 with no regard for efficiency, and because there were multiple total refactors of two apps. An annoying problem I deal with almost every day now has a permanent, personalized solution that took me ~3 hours and would never have otherwise happened.

The network itself is also such a project. I previously hobbled together a working unifi setup, but it was primitive and brittle. With LLM guidance, I was able to build something much more robust. TrueNAS scale for file backup that also runs Frigate for POE cam mgmt (similarly sandboxed), raspi running the unifi controller, another for homeassistant, etc. Absolutely miserable few days getting that dialed, but now that we're out the other side, it's very nice. Reminds me of building the house. You suffer more upfront in exchange for something that fits you like a glove. Very rewarding.

The past few weeks I've been building Blackbird

https://github.com/jbonatakis/blackbird

At a high level it's my take on how the execution aspect of spec-driven development should be handled. Where as most tools that are popular right now break a spec down into a task list and instruct your agent to work through it in a single session, I am treating agents as stateless. By this I mean a separate (headless) session is started with selected context for each task. This avoids context exhaustion, compaction (and the resulting confusion that can occur), and means that Blackbird can work through effectively an arbitrarily large task list.

Right now it's BYO-spec, but then it:

* breaks the spec down into a dependent-aware plan (DAG) composed of parent and child tasks

* executes tasks one at a time based on their status (ready to execute if all dependencies are marked as completed)

* allows you to (optionally) pause execution after each task to review, approve and continue, approve and quit, or reject the changes altogether

* (soon) treats parent tasks as an automated reviewer for all child tasks and optionally auto-resume those sessions to address the feedback

* and more

It's entirely bootstrapped, and so far I'm quite pleased with it. I also wrote a post[1] today about some of the concepts I had in mind as I was defining the architecture.

I've just started a new personal project, a C++20 library for running composable visitors over data documents and data models with JSON/CBOR semantics, DOM-less.

Basically, if you define a data model with bindings, you can inject data into it or extract data from it by running SAX-style visitors. You can use serializers/deserializers for standard formats like JSON/BSON/CBOR/CSV, or you can define custom formats for formating structured data however you want to. You can also run a serializer visitor on a deserializer to convert between formats. You can compose filter visitors to extract a subtree or filter out keys. And it's designed to fit on microcontrollers with very limited dynamic memory allocations, because it either streams data on-the-fly or works directly with the underlying data format in a big preallocated buffer.

I worked with libraries that offered a subset of these features before in my professional career (even built one myself), but recently I've had an epiphany (a document can also be used as a data model) that makes me think I can create something elegant and unique.

A GBNF to json schema translator in such a way that structured responses from LLMs can be serialized back into string confirming to the original grammar.

Initial results have been surprising in that even when using structured output, some of the generated json schema breaks the generation process in a way that syntactically invalid json is returned.

I'm working through major providers to determine which are stable enough to rely on.

Hi, I’m splitting my time between multi-cloud governance and optimizing my "vibe coding" workflow: Kexa (https://kexa.io)

An open-source multi-cloud governance framework powered by a YAML rule engine. We just reached a milestone by adding Database (DB) support.

The goal is to allow developers to audit configuration and compliance directly within DB instances, alongside standard cloud resources (AWS, GCP, Azure, K8s). We’re focusing on keeping the YAML rules as agnostic as possible so the same logic can apply across different environments without rewriting everything. rtk (https://github.com/rtk-ai/rtk)

This is a "scratching my own itch" project born from using Claude-code. While vibe coding, I got frustrated watching the agent spam ls -al or cat repeatedly just to "orient" itself.

It creates two main issues:

    The Token Tax: It burns through tokens for info the agent already has.

    Context Pollution: The context window fills up with redundant noise.
rtk acts as a CLI wrapper/filter to make LLM interactions more signal-to-noise efficient. It silences or summarizes redundant outputs so the agent only receives the necessary "delta." It’s a simple attempt to keep the context clean and make sessions last longer before the agent loses the plot.

👤 planckscnst
I'm working on lots of projects. My favorite is what I call "context bonsai" where I'm giving LLM harnesses the ability to surgically edit the context. It's available as a tool. You can say "remove that failed debugging session and write a summary of what we learned." Or you can take a more hands-on approach and say "remove messages msg_ID1 through msg_ID2". The removal leaves a summary and keywords, and the original messages can be pulled back into context if the LLM thinks they're useful.

I would really like people to try it out and report bugs, failures, and successes.

https://github.com/Vibecodelicious/opencode/blob/surgical_co...

I'm currently trying to get the LLM to be more proactive about removing content that is no longer useful in order to stay ahead of autocompaction and also just to keep the context window small and focused in general.

I'm working on a language learning framework based on the ideas of comprehensible input and spaced repetition learning.

The idea is you take a book you want to read, and it gets translated but also rewritten to match your current learning level. And as you read/listen it introduces new words to learn, reinforced by spaced repetition.

We're taking a trip to France this summer and I'm hoping to have something usable for at least a couple months before we go.

👤 heyitssim
I love making games, and I’ve been building a no-code game engine by extracting reusable components every time I ship a new game. It started as me scratching my own itch, and now it’s turning into a real platform.

Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click. For game logic, I recently added a visual event system I’m really excited about. It’s kind of like Unreal Blueprints, but focused on 2D. You pick a trigger, wire conditions, and chain actions in a node graph [1].

Big challenge right now: most people who want to make games needs assets, and don't know how to get/make them. So I’m building a marketplace where pixel artists can upload tilesets/characters, and unlike itch.io, assets are usable directly inside the engine. No ZIP downloads or import setup, just browse and drop into your game. A preview here[2].

Also, if you want to use the editor but ship elsewhere, you can export terrain, animations, and hitboxes to Godot 4. Nothing is locked in.

The engine/editor is at https://craftmygame.com if anyone wants to poke around! And you can test a games here[3][4], and 1 multiplayer game I've tested IRL in a bar [4]!

Working on Postkit - auth, permissions, config, metering, and job queues as pure SQL functions inside Postgres.

I've been using Claude Code to spin up apps quickly, and I kept needing the same infrastructure every time - user auth, permissions, usage tracking, job queues. So I pulled it all into one SQL package that lives in Postgres. Now when I start a new app I just tell Claude to use Postkit and all that stuff is already there, no external services to set up. I can focus on the actual product and iterate fast.

It was also a good excuse to actually use stuff I'd studied for system design interviews - Zanzibar-style ReBAC for permissions, a double-entry ledger for usage metering, transactional job queues with SKIP LOCKED. ~15k lines of SQL across five modules, with a Python SDK. The SQL works from any language though.

A personal finance app called “Predictable” that takes chaotic sloshes of money and turns them into steady streams of cash. You tell it “I receive this much money weekly/monthly/on the first and fifteenth/when Mercury is in retrograde, and I have these expenses at other various intervals” and it evens everything out into a constant weekly flow of cash by, essentially, buffering. Any overflow or underflow goes to a “margin” bucket which basically tells you how much you could spend right now and still have enough for all your recurring expenses.

Fetching every church from IRS data; using a small local Mac mini LLM to match to their Google result, fetching site and (eventually) running a data enrichment LLM pass to determine various positions, metadata, and services offered.

Working on Memory Store: persistent, shared memory for all your AI agents.

https://memory.store

The problem: if you use multiple AI tools (Claude, ChatGPT, Cursor, etc.), none of them know what the others know. You end up maintaining .md files, pasting context between chats, and re-explaining your project every time you start a new conversation. Power users spend more time briefing their agents than doing actual work.

Memory Store is an MCP server that ingests context from your workplace tools (Slack, email, calendar) and makes it available to any MCP-compatible agent. Make a decision in one tool, the others know. Project status changes, every agent is up to date.

We ran 35 in-depth user interviews and surveyed 90 people before writing a line of product code — 95% had already built workarounds for this problem (custom GPTs, claude.md templates, copy-paste workflows). The pain is real and people are already investing effort to solve it badly.

Early users are telling us things like one founder who tracked investor conversations through Memory Store and estimated talking to 4-5x more people because his agents could draft contextual replies without manual briefing. It helped close his round.

Live in beta now. Would love feedback from anyone who's felt this pain! :)

Learning the autonomous coding, there are so many different skills, tools and ways and only some of them seem to work.

That means I have to: - build something so I can evaluate the results. - track each of these projects separately otherwise they turn into dust after quite some time. Gladly claudesidian seems to be working well with the unstructured stream of inputs. Feel like hooking it up with some task tracker cli and calendar and notifications could make life a bit better too. - plan next projects to keep evaluating other skills and tools

It’s been discussed so many times the amount of new or personalized software that appears and will appear and it seems so true.

Whatever I built I am actively using myself - a text rewriter that cleans some of the AI speak and has MCP and cli (at https://www.refineo.app). Math teaching and solving extension at https://math.photos and a self hosted stock opportunity discovery tool that runs locally. This is just to automate what I did before manually and scale it up a bit.

> Any new ideas

There’s no product yet to cover the needs of all of us launching the software into the internet void. Any ad platform out there is a hot and very outdated mess and I just can’t. There is going to be a better way with all the capabilities we have and someone is going to really nail it.

The second bubble there is a tool for 3D visualization and analytics of Claude Code sessions. The sample conversation is the one that made the tool itself!

That was a fun toy I learned a lot from. I’m not expanding that but am working intensely on the first bubble:

thinkt a CLI/TUI/Webapp for exploring your LLM conversations. Makes it easy to see all your local projects, view them, and export them. It has an embedded OpenAPI server and MCP server.

So you can open Kimi and say “use thinkt mcp to look at my last Claude session in this project, look at the thinking at the end and report on the issues we were facing”.

I added Claude Teams support by launching a Team and having that team look at its own traces and the changing ~/.Claude folder. Similar for Gemini CLI and Copilot (which still need work).

Doing it in the open. Only 2 weeks old - usable, but early. I’m only posting as it’s what I’m working on. Still working on polish and deeper review (it is vibe-crafted). There’s ergonomic issues with ports and DuckDB. Coming up next is VSCode extension and an exporter/collecter for remote agents.

I’m building PointWiseSystem, a browser-based habit and responsibility system I originally built for my own family.

It uses a simple points model instead of streaks or financial-style tracking to make expectations visible, progress clear, and follow-through easier.

In real use it’s solving three main problems: - As a Family Chore Chart — a digital chore system that actually gets kids engaged with responsibilities using points and rewards. - As a Personal Habit Tracker — a way for individuals to organize routines, add notes, and earn points toward meaningful self-defined rewards. - As Complete Homeschool Management — tracking assignments, logging progress by subject, and generating reports and transcripts for multiple students.

It’s entirely web-based (no app download) and works on phones, tablets, and desktops. I’m actively iterating on it based on real use, and it’s been most useful in situations where simpler systems actually get used instead of abandoned.

Borrow This And Improve It - an app for tracking repairs to a thing (right now it's bicycles only, planning to extend to other things like leaf blowers and electronics) and giving away half broken things or repaired things to others but with the advantage of also giving away the repair history for something. So for example, I found a bicycle in the trash, fixed it up with a few new parts (less than $6) and soon I'll try to give the now repaired bicycle away to a new home, plus a QR code that links to its repair history. The idea being that knowing how something was fixed once will make it more likely that it would be fixed again.

I'm building a safer Agent system for SMBs.

The biggest problem is internal knowledge and external knowledge systems are completely different. One reason internal knowledge is different it is very specific business context and/or it's value prop for the business that allows charging clients for access.

To bridge this gap, the best approach is to train agents to your use case. Agents need to be students -> interns -> supervised -> independent before they can be useeful for your business.

I’ve been experimenting with a live win probability predictor for the 10-player arcade game Killer Queen. The goal is to predict the winner in a causal, event-by-event fashion.

Right now I’m struggling to beat a baseline LightGBM model trained on hand-engineered expert features. My attempts at using a win probability head on top of nanoGPT, treating events as tokens, have been significantly worse. I am seeing about 65% accuracy compared to the LightGBM’s 70%. That 5% gap is huge given how stochastic the early game is, and the Transformer is easily 4 OOM more expensive to train.

To bridge the gap, I’m moving to a hybrid approach. I’m feeding those expert features back in as additional tokens or auxiliary loss heads, and I am using the LightGBM model as a teacher for knowledge distillation to provide smoother gradients.

The main priority here is personalized post-game feedback. By tracking sharp swings in win probability, or $\Delta WP$, you can automatically generate high or low-light reels right after a match. It helps players see the exact moment a play was either effective or catastrophic.

There is also a clear application for automated content creation. You can use $\Delta WP$ as a heuristic to identify the actual turning points of a match for YouTube summaries without needing to manually scrub through hours of Twitch footage.

If you know what an AKAI MPC Live, MPC 3000, SP404, SP1200, BOSS RC-202, Alesis 3630, Serato Sample, S950 filters, and stem separation does, then you'll love seeing these "greatest hits" up in a terminal interface.

Last year while on vacation in Costa Rica, I started scratching my own itch for locating and organizing samples, which quickly evolved into adding more and more features while keeping it tactile and immediate. It was too fun to stop so I kept going. After a few days I was happily making beats in it, and since then it's only gotten better.

It's live and totally free to use, and works in macos & Linux (Windows soon). I'm about to launch v1.0 now, just working with folks in the community to round out the Factory Kits a little more for users new to beatmaking.

Turns out, making beats with no mouse and a terminal interface strikes the perfect balance of hardware feel and software power, and I'm loving the result. Been sharing it with folks in my beatmaking sphere and have plans to continue expanding its reach through more collaborations, contests, and in-person events.

Hope it brings you as much joy as it does to me :)

I’m building an app that facilitates discovery and eases payments for roadside stands that sell produce, honey, maple syrup, eggs, firewood, crafts, etc. The concept is that any roadside vendor can sign up for free (forever, no add-ons or upsells) and they have an online home for their home business. The vendor can list up to 3 stands and show off the products they sell in each stand. Users can discover stands near them by list, search, or map, view the vendor and stand details, ratings, payment methods accepted, etc. When arriving at a stand the user can scan a QR code which opens a web cart, allowing them to add products they are going to purchase and then “check out” using one of the vendor’s stated payment methods like Venmo, CashApp, PayPal, Apple Cash, Zelle, or good old hard currency. We make these payments easier by standardizing the check out experience but we do not facilitate payments at all - these stands have always been and will continue to be self-serve on the honor system. Once you’ve paid, you get a receipt and take your goods. The vendor gets an alert that a sale intent was started and by which method so they know where to look for their revenue. In the future we may help with some basic reporting and very light inventory management if vendors ask for it. We allow users to alert the vendor if a stand is out of stock, which is also reflected in search so other users are informed as well. Users can then ask to receive re-stock alerts as the vendor restocks. Then of course users can favorite stands and products, share them, rate them, and create shareable collections of stands they curate (The Honey Trail or Summer Sweet Corn All-Stars, etc.). Eventually we will be adapted for events like farmer’s markets, craft fairs, and christmas markets. I built this because I am a maple syrup producer (tapping starts in a few short weeks from now) and I’m starting to get into mass sales of my syrup. I felt like people who produce and sell these products put a lot of hard work into the process and deserve a legit discovery tool as well as a basic stand management system that does not make them change their process or get in their way. An app like this costs basically nothing to run and I will ensure it is free to use as long as I am in charge. I’m testing this week and likely soft-launching in the next couple weeks - the goal is to be online around March 1. It was just going to be web-only (Supabase with a Svelte front end) but after Claude put me in timeout last week I tried Antigravity and now have 80% of an iOS app and will scaffold my Android app in the next month - so native apps will follow a web release pretty quickly.

vibebin is a self-hosted platform for running persistent, isolated AI coding sandboxes on a single VPS using Incus/LXC containers:

https://github.com/jgbrwn/vibebin

It automates installing and managing Incus, Caddy, and SSHPiper, provides a TUI for container lifecycle and quick actions, a web admin (built/compiled on the container) for toggling and updating AI coding tools (Shelley, Claude Code, OpenCode, etc.), and a background sync daemon that keeps Caddy routes and container metadata in sync.

Each container exposes coding tool web UIs on isolated ports and supports direct SSH/VS Code Remote access, so you can run multiple independent coding agents against real project files without exposing your local machine.

The project emphasizes simplicity and recoverability for running agents locally: containers are persistent, optionally routed via reverse proxy with basic auth, and tracked in an SQLite DB so setups auto-heal after restarts. It’s written in Go, includes an install script for one-line deployment, targets modest VPS specs (4–8GB RAM recommended), and bundles helpers for DNS and provider automation.

Ideal if you want a lightweight, opinionated way to host multiple isolated AI dev environments on your own server instead of relying on hosted agent platforms.


👤 vincentjiang
I've been thinking about this a lot after shutting down my previous startup. One problem I've identified is that tools like Claude Co-worker or Claw Bots will never truly deliver reliable agentic outcomes for people due to the fact that scaling a human-like agent is paradoxically harder than scaling a script.

- I see a lot error propagation with CUAs

- A GUI is very flakey and it produces a lot action latency

- There're hidden states behind each screen that CUAs simply can't capture

- Token consumption is absurd (but I guess this will alleviate as LLMs get cheaper)

What do you guys think? Any good ideas what'd be a good counter to this?

- Persistent local file system & mounting local folder as removable disk with ZenFS.

- Support playing Flash games and run DOS games (save game persisted). Yes, you can play Doom and copy your savegames to continue.

- Some accurate remakes of Windows 98 apps, some made by me (Solitaire games, Minesweeper, Notepad) some are existing ports (Pinball, JSPaint, Webamp, etc).

- Some other fun stuff

Trying to use ESNs as a random projection for audio data and potentially rendered text data for some AI workflows. Seeing it I can use the echo states running both forward and backward through the data as a holographic representation which would act as a temporally dense token for potential use in LLM or audio encoder inputs.

BrowserBox embedding API plus a bunch of other side projects. BrowserBox is a remote isolated browser with a variety of DLP, NIST 800-53 controls and FIPS 140-3 encryption at rest. It can function as a fully automated embeddable browserview for AI workflows, isolated sandboxes, generic whitelabeled RBI and multiple other use cases. It's a heavy target of abuse by non state actors in sanctioned countries so I had to add ID verification to get a trial key.

For the last couple weeks I have been building dwata and I am going to submit today for Google Gemini Hackathon.

https://github.com/brainless/dwata

dwata is built on the idea of multiple, task-specific agents. Right now it has only one agent that can be run on an email to extract regex patterns for financial data. This enables high performance data extraction from emails or documents (in future) without sending each email to an LLM.

dwata has an email scan which tests simple keywords and regex patterns, groups by sender emails, sorts by number of emails per sender (highest first), and filters out groups where the emails do not seem to be from a template (typical transaction emails are from templates). This is deterministic code in Rust. Then dwata can use the regex builder AI agent to take one email from the group and build a regex pattern to extract extensive financial data - (optional) who sent, how much, (optional) to whom, on which date, with (optional) reference ID.

The generated patterns are saved to local DB and run for the email group (by sender) which was used to generate the regex. That gives a very high performance, AI enabled financial data extractor.

Soon, I will focus on events, places, people, tasks, health and other data. All data storage and processing is local. I am testing exclusively with Google Gemini 3 Flash Preview but dwata should be able to run really well on small LLMs, ones up to 20b parameters.

I am preparing for launch, the builds are not ready yet, but if you want to try, you can compile (Rust and npm tooling needed). Sources to nocodo will also be needed (https://github.com/brainless/nocodo).

It’s local-first, syncs across devices, and everything’s encrypted in transit (we do have your email for subscription tracking and analytics). Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more.

Most recently, we added support for benchmarking (create custom dashboards tracking nav and value chart of subsets of your portfolio) and us stocks, etfs etc.

- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference

- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more

It's getting close. I'll do a show HN on it sometime soon.

I’ve been working on https://og.plus, a service that creates unique Open Graph images per page on a website.

It does this by taking a screenshot of the page, but before it does that, you can modify what’s displayed in the screenshot with CSS, tailwind classes, meta tags, or HTML templates.

If you connect your website to it, the only thing you need to deploy to your web app are a few meta tags. The OG+ servers do the heavy lifting of processing the meta tags to setup the page, take a screenshot of it, and serve it up to the consumer.

The other cool thing it does is generate a different Open Graph images per social network so they all get an image for the exact size they works best in their previews. The CSS or HTML templates are aware of this too so you can display different content to specific social networks.

A free interactive SQL tutorial that will get to the level of being a data analyst. It's Alice in Wonderland themed.

I used to be a coding bootcamp instructor, TA and guest lecturer. I've noticed more and more people need to learn SQL for various different reasons. With Claude Code, I've noticed it is easy to create a prototype so I'm more concerned about lesson scaffolding. I'm hyped about AI but they're not great with lesson scaffolding.

I'm 33% to 50% done. I've already noticed the way I scaffold the lessons is unconventional. For example, for the first 50%, I don't want students to know what tables are. It's too much all at once, everything should be small bites before the big concepts get introduced.

If anyone is interested in testing the beta version, let me know. It will be up within the next 2 weeks probably. My email is in my profile.

I’m building a small LLM-based text rephrase tool, but it turned into something different than I expected.

Inspired by a TED talk I saw [0] where the researcher from Microsoft displayed a program with AI assisting with thinking while someone was reading and annotating a document. They claimed it was a way to sharpen critical thinking instead of killing it. They didn't release the product, but I figured it was cool and useful, so I've spent the weekend creating it. It's been a great way for me to practice using agents, and I've learned a lot from this process.

I am using KVM from Cloudcone (their virtualization software was hacked about a week ago) and I am using RPI4.

It comes with a rigid (fast but wholly inaccurate) simulation, as well as DEM (which will make you cry and want to build a new computer). Having lots of fast cache helps with the DEM sim

Since we recently moved out of the city and into the mountains of Switzerland, I had a niche problem... agreeing with my buddies which is the best ski field to meet at when we all live in different towns. So I made a little web app to help:

https://skicompromise.ch

This was a fun little project I did over the Christmas holidays but only finished off recently. Basically I precalculated the public transport time between the most populated towns in Switzerland to every ski field (about 350 of them!) and then built a little web app around it using Django.

You can choose to prioritise shortest (lowest time overall) versus fairest (smallest variance in group members).

Totally free to use. Next steps are to integrate it with live snow conditions/open lifts...

Claude did help a lot with the FE part. The biggest part was actually finding the best public transport stop for each ski field - that was a very manual process trawling through skimap.org images and Anreise info on ski resort websites.

https://reposit.bot/

Having done a lot of back and forth with LLMs and at the end throwing away learnings from a conversation felt so wasteful - reposit allows you to /share a summary of the valuable learning from your LLM chat for others to discover.

At the beginning of researching a problem, your agent can search reposit just like Context7 for docs. This way, even if you opt out of sharing your data with your LLM provider (as it's all or nothing), you can choose to publicise a solution to your problem with very little effort.

I'm working on extracting valuable learnings from open-source community projects as a starting point now (with attribution), as it probably needs a larger database to be valuable for users to install and use.

You can also self-host it and share privately within the company.

I'm making a suite of simple Windows tray apps that do just one thing. They often have existing equivalents but I think my version is better and/or simpler ;-) All work starting with Win7.

The first three are:

- miniWake: keeps the computer awake

Alternatives: Powertools; USB mouse jigglers

Features: installs without admin rights; triggers invisible mouse events; turns off at LOCK, turns back on at LOCKOFF (saves battery); manual turn off or on via double-click on the icon

- miniRec: records system audio + microphone to mp3/wav

Alternatives: various utilities like Voicemeter, AudioRouter, or some DAWs

Features: does not require any special driver; installs without admin rights; light on resources; "invisible" to third parties (video meetings); auto turn off after 5 minutes of silence (configurable)

- miniCron: system scheduler as a service

Alternatives: NSSM - the Non-Sucking Service Manager; Splinterware

Features: launches any program at any given time (cron like but without cron syntax); kills the current task when the service is stopped; reads and logs stdin/stderr; very light on ressources and very simple

Two others are in the works.

Still working on Gaming Couch, a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. Back in December Gaming Couch hit the front page of Hacker News, you can check it out here: https://news.ycombinator.com/item?id=46344573

At the moment working on the 3rd party development tools so in the future anyone can make their game dev dreams a reality and make a simple and fun multiplayer party game for the Gaming Couch platform, ideally in only one weekend!

If you're an interested game dev that would like to beta test the dev tools, hit me up either here, via Discord (link available from https://gamingcouch.com) or by emailing me at gc[dot]community[at]gamingcouch[dot]com!

The TL;DR of Gaming Couch:

- Currently in free Early Access with 18 competitive mini-games.

- Players use their mobile phones as controllers (you can use game pads as well!)

- Everything is completely web-based, no downloads or installs are necessary to play

- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!

👤 joenewbry
I'm working on Memex: https://github.com/joenewbry/memex

It's inspired by a moment a few years ago when I realized I had no history of what I had worked on in the past.

It let's you quickly get answers to questions like:

- What did I work on last week? - What was that one hacker new post about compiler optimization that I forgot to bookmark last week?

And it has MCP support so it plays well with Claude.

I've used it recently to target specific job applications by adjusting my resume based on what the job application is looking for and what I've worked on in the past... Claude one shots this (because it has context from Memex). And it feels amazing!

Also, the name Memex comes from Vannevar Bush's 1945 article "As We May Think". He originally thought of as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility". The individual was supposed to use the memex as an automatic personal filing system, making the memex "an enlarged intimate supplement to his memory".

And he created a word - memex - which is a portmanteau of "memory" and "index".

The wikipeida entry here has more information: https://en.wikipedia.org/wiki/Memex

It's been a slow start for me. But now, between the cli interface and the MCP connection with Claude I find that I'm starting to use it instead of:

- Bookmarks - Lists / Bug Tracking

And even more exciting it's unlocking capabilities that I didn't have before:

- Can ask Claude to review the last week of work and remind me of things that I might still need to do - Can prevent randomization when someone asks me how to configure a server that I set up a month ago. Now I just ask claude and it checks in Memex. And I can send over a nice .md file

Building a tool for finding scientific papers behind real-world OSS projects: https://papergrep.dev/

This is a follow up to an idea I had years ago https://news.ycombinator.com/item?id=13022649, which is now semi-automated (with lots of manual curation as the last step).

The biggest challenges:

- how to organize all this info in a nice way

- where to find more time to read all the gems I've found so far :)

UPD: formatting

I'm still building https://techposts.eu - the Hacker News for Europe!

Some stats so far:

- 200 users

- 378 startup jobs

- 500+ posts

- 2800+ funding rounds

- 1700+ startup companies

- 5000+ investors

The next part of the project is Tech Posts Intel: a lead gen tool using statistical methods to predict which companies should have a funding round coming soon. I'm hoping to soft launch it this week.

I'd love to hear anyone's feedback on the website. Advice on how to get inbound links in 2026 would also be greatly appreciated!

I've spent my weekend building asterbot: https://github.com/asterai-io/asterbot

Asterbot is a modular AI agent where every capability (such as tools, memory, LLM provider etc.) is a swappable WASM component.

Components are written in any language (Rust, Go, Python, JS), sandboxed via WASI, and pulled from the open asterai registry. Think microkernel architecture for AI agents.

I'm building Dropnote, a small tool for physical businesses.

Someone who is physically at a place can scan a QR code and leave a short message in their browser. No app, no account. Messages are asynchronous; staff reply when available. This is not live chat. It's meant for in-the-moment feedback or questions that don't justify interrupting staff or becoming public reviews.

Constraints: async only, anonymous by default, no customer tracking, messages tied to specific physical spots

Free early access until Sept 30, 2026 (+ one extra free month). No credit cards (no payments yet). I'd love to hear your Feedback. Thank you.

I'm building CatchIntent (https://CatchIntent.com). The goal is to help turning social conversations into qualified warm leads.

Started with it because I was struggling with finding relevant conversations about my first app where people are exactly asking for what I'm selling, only that I was missing those conversations and people. Build a POC, tested for myself and started getting good leads, so I converted it into my second app.


👤 geetuu
We ran into the annoying Envoy 503 bug in our prod and needed some quick tools to help figure out what was going on with TCP connections and HTTP requests.

[TCPFinMonitor](https://github.com/vishnugt/TCPFinMonitor) [Live Version](https://keepalive.gt.ms/)

This tool tracks TCP FIN packet timing to see how upstream connections are closing and how keep-alives behave. It helped me spot when connections were closing too early or timing out, which was causing those 503 errors.

[hyperbin](https://github.com/vishnugt/hyperbin) A fast, minimal httpbin clone written in Rust. It’s way faster(20x throughput) than the usual httpbin and useful for testing HTTP clients and debugging requests without extra noise.

These aren’t polished, just some stuff I needed to iron out the issue.

https://github.com/Leleat/git-forge

From the README: "[git-forge is a] simple CLI tool for basic interactions with issues and pull requests across GitHub, GitLab, Gitea, and Forgejo".

Right now, I am looking into better testing. Currently, I do testing by mocking the forge APIs and then running git-forge against them with TypeScript. But not everything is testable that way. The TUI is pretty much untested. So I now want to port at least the tests to Rust (I am probably gonna leave the mock API in TS) and need to look into how to tests TUIs, which is a bit of a challenge since not only is Rust my first "systems programming language", I am also not knowledgable in Terminal/TUIs...

Working on https://allscreenshots.com - a screenshot API for developers.

I got frustrated with existing screenshot services choking on cookie banners, rendering half-loaded pages, and serving bloated images. So my co-founder and I built one that auto-dismisses cookie consent dialogs using Playwright heuristics, serves AVIF-first from Cloudflare R2, and supports geo-distributed rendering so you can capture pages as they'd appear from different regions.

Spring Boot + React + PostgreSQL. Bootstrapped after selling a previous ecommerce SaaS.

Currently documenting the whole build in a 30-day series on the blog if anyone's into that sort of thing.

https://www.criticaster.com/

A metacritic like website but for any product.

It analyzes thousands of professional critic reviews to find the best of the best.

I started building this because I adore how metacritic analyzes professional movie/game/tv show reviews and calculates a meta score for each title. In my experience it’s the best way to discover new things to watch or play, and I’ve often wished something like this would exist for when I want to buy a product.

This year, I decided to start building it myself and Criticaster is the result.

For a given product category we collect all professional reviews of a given product, analyze each to assign them a score and then calculate an average critic score.

The goal is to become the most trustworthy source to make product decisions.

Very curious what y’all think!

Out of curiosity, i am building a WebAssembly VM where every control flow instruction (branches, calls, loops, returns) advances a rolling AES chain state.

Branch targets are encrypted — decryption only works if the chain state is correct, which requires every prior control flow decision to have been correct, all the way back to the run key.

I'm using single round AES instructions which require AES-NI Wrong key, modified binary, or even a debugger breakpoint causes execution to instantly collapse into garbage. Its written in Rust and currently passes 261/276 Wasm spec tests (remaining 15 are cross-module imports).

Currently supports SIMD, atomics, exception handling, memory64, tail calls, and WASI with sandboxed file I/O and TCP sockets.

Im tinkering around with porting it to a sel4 backend in adition to the posix backend.


👤 vulkoingim
Built my own Spotify recommendation egnine after getting tired of Spotify’s repetitive recommendations.

You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.

It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created - if you don't follow much or any artists, then you should enable that in order for the service to be useful.

I started working on https://ottex.ai three months ago just for fun to test Gemini 3 Flash as a voice-to-text model (by the way, it’s amazing, but a bit slow). However, it quickly transformed into my main project.

It's a free macOS app written in Swift that allows you to type with your voice. It supports local models and BYOK (Bring Your Own Key) with a bunch of providers.

You can assign different models and post-processing steps to polish the text. For example, I have a setup for Obsidian that transforms my voice into clean, formatted Markdown. Or, when I use it inside VS Code, it switches to the Parakeet V3 instant local model.

I also am building Phaestus, a 0 to product system, that builds entire products from scratch.

https://www.mikeayles.com/#phaestus-wip

It is capable of creating a PCB (and outputs gerbers, bom, pick and place files), an enclosure (written in SCAD, outputs an STL for printing), and firmware, which it's able to compile using a pio runner on railway and provides a binary, but also has a webserial flasher for ESP32's.

There is a blog here, but i've been focussing on getting things finished, as I built it for a hackathon ending today.

https://phaestus.app/blog

I need to update the blog & writeup, because I have the first product it created, a bluetooth remote control. It wasn't without issues, but I have a working PCB, in an enclosure that was printed from it's design, running firmware it generated.

I've been on and off attempting to reverse engineer old Sierra games in Godot. I've brought in AI to build tooling to speed up asset extraction from the old game files which has been a huge help. I just got building placement working last night which was a huge win.

This is part of a small hobby where I try to recreate aspects of old games myself to see how I would implement them. I eventually hope to have the skills to create the kind of game I miss playing when I was a kid 30 years ago.


👤 AJRF
A project builder.

I often have ideas, then spin cycles on starting the project, getting auth in place, making a marketing page, doing SEO, building and configuring pipelines for mobile app release, etc, etc.

My project builder just takes a name, a few configuration options (do you need payments? Analytics?) and spits out a templated build with Terraform that I can 1 (okay maybe 3) click deploy to GCP + App Stores.

The nice thing (I got help with Claude Code) is that now all my projects are in one place, I have a dashboard where I click in to and edit the code (with hot reloading - it deploys code-server and the applications in a small Kubernetes cluster, each project has its own pod) and when I am done editing I just click Deploy and it updates the "production" service in Cloud Run.

Not really interested in selling it as a service or anything (it's a bit too opinionated for that), but it's a very fun project to work on. I need to make Git + Versioning of the code work right now you only have a single copy of the code which isn't great!

Today I'm writing a Postgres native function to derive UUIDs from an integer primary key using AES intrinsics. This lets me expose public UUID keys while still using an efficient 64-bit sequential primary key.

👤 shevy-java
I am currently not really working on anything major, due to time constraints.

However had, on my semi-immediate todo list in the future are:

- improvements to the scripts I use to compile software from source; I want to be able to build a complete LFS/BLFS without any interaction (I know there is AFLS but I don't like the format or restrictions; I literally want to be able to do everything here via actionable scripts at every moment in time, including using git sources rather than old releases)

- continue on the unified widgets project (e. g. use oldschool GUIs but also for the web "GUIs"). Describe once, run anywhere, in any programming language. This is obviously way too much for a single person, so I mostly want to get the foundation right, prototype primarily in ruby, then add python and java to it. The "end format" should be for normal people, e. g. they should be able to describe everything in one format, and then have that be the basis for every GUI.

- continue working with regard to bioinformatics, also with a focus on normal people (non-tech savvy people). Most bioinformatics software was written by math-heavy tech-centric people, which makes sense. It's not trivial to work with that (we have AI to work around this to some extent, but I feel that many people who use AI don't understand the underlying components; I kind of want something like a Linux from Scratch for all bioinformatics-centric software. Like not just use it but full and useful explanations that are not too technical, but also not too overly long.)

Hopefully gem.coop becomes a viable alternative to rubygems.org - I hate the corporate identity rubygems.org adopted (and you can see the fall-out in other areas, e. g. Heroku dying right now, which kind of means ruby will die too, if all use cases are eroded despite the pro-corporate focus RubyCentral embraced). Unfortunately things seem to become worse in general - I was hoping LadyBird would be a real competitor. The moment you make any statement that they perceive as "criticism" is the moment their code of conduct kicks in and locks you out. And that's not even after a first release; imagine how they will operate once people come in with complaints about LadyBird having problems.

The world wide web used to be a LOT more open in the past.

I'm going to do the hyper-literal take of what are you working on literally today, since I'm always working on the same old project Marginalia Search and I have been for going on five years now.

* Integrating website liveness data into the crawler to make more informed decisions about whether to keep or wipe data from a website if it can't be reached while crawling

* Working out why the liveness data gathering process isn't stopping as scheduled.

* Deploying a voluntary max-charge request header for the commercial API

* Making website URL elements searchable. They should be already, but are not for some reason.

* Maybe looking into an intermittent stacktrace I get on one of the index partitions.

No blockers.

I always wanted a minimalistic CSS framework for my projects, so I started to create my own: THINK

THINK is a modern CSS-first UI framework built on semantic HTML, custom elements, and data attributes. Uses :has(), container queries, and density scaling. No classes, no build step.

It‘s work in progress but I‘m pretty happy with the outcome so far, especially the data table component and automated Insights. I know it‘s not AI driven - but it works pretty okay for quick insights on the loaded data.

👤 arkforge
I'm working on ArkWatch (https://watch.arkforge.fr) - a monitoring API that you can use with just curl, no signup required.

The insight: most solo founders need basic "alert me when this changes" monitoring, but existing tools force you through signup flows, credit cards, dashboards you'll never use. So I made it dead simple:

    curl "https://watch.arkforge.fr/api/check?url=https://your-site.com&email=you@email.com"
That's it. It watches the URL and emails you when content changes. Free tier = 10 checks/day, which is enough for most side projects.

I built this because I kept forgetting to monitor my own stuff. Now it's live and I'm trying to get my first 5 beta testers. The challenge is marketing - I'm a developer, not a growth hacker. Learning as I go!

What's been your biggest challenge with your current project?

https://catchditto.site

I'm building Ditto — it clones websites with 100% visual accuracy and outputs a proper React app with named components and preserved structure.

The problem: you find a design you love, want to use it as a starting point, and your options are either manually recreating it or using a tool that spits out a tangled mess of divs and inline styles. CatchDitto gives you an actual codebase — clean component hierarchy, sensible naming, structure you can extend without wanting to rewrite everything first.

I'm still iterating, would love to hear what others think.

I launched https://rebrain.gg/ a few days ago.

It's a bit like Reddit but focused on learning. (Doom learning instead of doom scrolling)

You 1) upload a source 2) direct the kind of questions you want to be asked 3) start answering (and if you get the answers wrong, you can discuss the problem with "AI").

You can read other people's sources, questions, answers and their discussions with AI too.

And if you're learning the same thing as other people, you can join communities to share sources/questions.

It's still very early on, so I'm very interested in any feedback.

Jumbo HN https://threeemojis.com/en-US/play/globs/en-US/demo?size=jum...

There is still some bugs I am tracking down (open the page in a private browser if you hit stale data) but the game has really come together lately and been a lot of fun, I hope you all like it!

Can't really share any useful link at the moment, but I’ve been working on a solution based on the C1001 mmWave sensor. It collects telemetry throughout the night, including respiratory rate, heart rate (BPM), number of turnovers, apnea detection, and overall sleep quality - you just need to hang it around the bed. The data is sent to a server, which generates a nightly report and passes it to an LLM for analysis.

I've decided to do it simply because of my grandmother: she dislikes bracelets and smartwatches because they’re uncomfortable and she often forgets to wear them. A contactless device could be much more practical for her and for many people like her.

Working on pg-fs, a postgres backed file system abstraction for ai agents. So I agents can be given their familiar file primitives, without

A version of it powers my local rubber duck thoughts and voice note store. Like an explicit chatgpt memory store, helps with information fomo cause I know finding the needle in haystack would be easy.

A south african wireguard-based consumer VPN service - surprisingly complex under the hood, about 6 months in the making so far!

Apple app store review is the biggest hurdle currently

I have been working on "scratch milling"[0] PCB's at home using my vinyl cutter/plotter and a engraving bit.

Inspired by Robin Debreuil his process and videos (see video the article and several forum posts). He is using a CNC but I figured regulating pressure is more important then depth, therefore my experiments with the plotter.

Currently dialing in the pressure/speed and amount of passes on a single layer copper board.

I just released Configmesh this week. It's a macOS app (with CLI companion) for e2e encrypted syncing and backing up of dotfiles and application configurations. You can sync for example stuff from ~/.config/, Application Support, *.plists, and so on, and add config sync to apps that don't support it natively

Fresh off the press

Working on https://eonia.art/, simple coloring page generator and picture animations.

I am using gemini-flash-image and veo-fast and it's impressive what you can do with them.

I released an open source library to remove metadata from images: https://github.com/fasouto/picscrub

Was more complex than I thought. Still missing support for some RAW formats and had to fix some bugs

I also created a website to showcase how it works -> https://picscrub.com/

if you need an idea: copy+paste online json visualizer (there are dozens of these) But with the one that click an element and it will show different programming language path selectors for that! i haven't found even one of this and it's difficult to see the path of element from sample data to put into an app when there are multiple levels and complex object

The State of Utopia[1] is currently fine-tuning an older 1 GB model called Bitnet, so that we have something beginning to have the shape of a sovereign model that can run on the edge. We think having model sovereignty is important for our citizens, and we are working on tools for them to easily further fine-tune the model straight from their browser. We are currently running a 30-hour training run on some simple hardware and through webGPU, so that no trust or installation is required.

We made it possible to run the model in webGPU and it is pretty fast even in that environment. You can see the porting process in my last few submissions, because we livestreamed Claude Code porting the base model from the original C++ and Python.

In a separate initiative, we produced a new hash function with AI - however, although it is novel, it might not be novel enough for publication and it's unclear whether we can publish it. It has several innovations compared to other hash formats.

We are running some other developments and experiments, but don't want to promise more than we can deliver in a working state, so for more information you just have to keep checking stateofutopia.com (or stofut.com for short).

Our biggest challenge at the moment is managing Claude's use of context and versions, while working on live production installs.

Everything takes time and attention and Claude Code is far from being fully autonomous building new productive services on a server - it's not even close to being able to do that autonomously. We feel that we have to be in the loop for everything.

Something I call a relational compiler. It makes Spark batch jobs run 10x faster by turning Postgres into a compute runtime.
