I believe I am the first human to have done this in a documented, verifiable way: maintaining a stable production-grade 500,000-line TypeScript codebase as a solo developer, using an AI coding assistant I built myself.

Built this code art project as a commentary on the recent wave of using LOC as a primary measure of engineering productivity It's now up to 350M lines of useless (but hopefully funny) code, constantly growing using GitHub actions and https://github.com/jshchnz/codemaxxing Unfortunately, GitHub has now sent me a notice to remove the repo within the next 14 days, so enjoy it while you can

A little background. For the last 1.5 years I lost what could be considered an embarrassing amount of money hiring other people to work on a project that I thought had potential, I got some important people involved, had some great coders, but couldn't launch. The failure was depressing, rejection by YC didn't help.. I had to take a job, I didn't enjoy and I had a girlfriend who stood by me despite going into debt. But bouncing back over the last 45 days I've taught myself Rails some Jquery, and Javascript and built this www.hangout.io. It's empowering to build something myself because I'm…

4 months ago sucked. Our technical co-founder quit after 6 months and we still had no product. My co-founder and I had been 'working' on our startup for 8 months. I say 'working' because as the "business people" - there wasn't a whole lot we could do except philosophize. We had gotten really awesome intros to some of the top VCs and entrepreneurs, but had nothing to show. And now we felt stranded. Had we wasted 8 months of our lives? Identity crisis? Check. So we did what any rational person would do - we ran to the mountains. Literally. In Boone, NC - we talked about why we started Knowit,…

I built CodinIT because I wanted that "Bolt-like" experience, but on my own terms. 100% Open Source The core idea: You should be able to prompt a full-stack application into existence, but the environment should be local, the models should be swappable (Ollama/LM Studio support was a priority), and the output should be standard code you actually own. A few things I focused on: Context Management: One of the hardest parts was figuring out how to feed the right file context back to the LLM without blowing out the token limit. I’ve implemented a custom indexing approach to keep the "vibe…

In the following case study, the AI coding agent rebuilds a core system invariant in just three days, with minimal human input, running 31 verification passes and correcting 201 errors, before shipping code with zero bugs, zero regressions, and zero technical debt. https://aisovereignlabs.ai/docs/case-study/liveSession/case-... Disclaimers: This case study is NOT: - a project written from scratch - yet another Rust transpilation - a clone of an open-source project found in the LLM's training data - a Super Mario clone in HTML It IS: - a complex application…

Hi HN! Last night, I live streamed myself coding this Llama 2 Agent on a Single GPU (Colab). After 6 hours it actually has some good results. How it works is it takes in your intuition (e.g. "I think x would be cool") and develops a business idea (with a name and branding colors) and a business plan. After the business plan is developed, it criticizes this plan recursively until the "Investor" prompt is satisfied with the plan. After all this it will generate the final MVP idea and pass it to a the React Engineer Agent I live coded 2 days ago…

For the last 6 months, I've been building ORUS Builder, an open-source AI code generator. My goal was to fix the biggest issue I have with tools like v0, Lovable, etc. – they generate broken, non-compiling code that needs hours of debugging. ORUS Builder is different. It uses a "Compiler-Integrity Generation" (CIG) protocol, a set of cognitive validation steps that run before the code is generated. The result is a 99.9% first-time compilation success rate in my tests. The workflow is simple: 1.Describe an app in a single prompt. 2.It generates a full-stack application…

We did a "Show HN post" 6 months back of our startup and we're very excited to show everyone how far we've come as well as the lessons we've learnt so far! It's been a roller-coaster so far and we think there's lot more of the same to come! We did apply for Ycombinator funding but got turned down :( But may re-apply soon :) For those that don't know, our startup is called Scirra and we make Construct 2 which is an HTML5 game engine (http://www.scirra.com). Our engine allows anyone to make HTML5 games without knowing any programming. It's only me and my brother working on this and we're based…

597 days ago, I posted about the project our team was developing - https://news.ycombinator.com/item?id=3183322 - here on HN, and today we're finally taking the wraps off what we've been working on since then. At it's core, what we've been building is an end-to-end solution for creating, storing, and working with structured content in a way that's accessible to anyone. You can check out an introduction - http://team.marquee.by/introducing-marquee/ and dig into the technical/philosophical details of our approach -…

I'm documenting everything about my process. From learning to code, to building the app, and all the way to my outreach efforts. I'm learning as I go and sharing it with everyone who's not a programer, and is daunted to build a software on their own. Trust me. If I can do it, anyone can! You can find my updates on: https://Claritask.com ...as well as video updates on https://www.youtube.com/channel/UCdmqmifW4kIcPclXigay1dQ Would love to hear your feedback on my progress and if you have any suggestions on what I can do better. There's so many task managers out…

Hey devs :) With 15+ years of UI kit building & design systems, my team is launching a platform that allows developers to build consistent & fully functional UI kits / web projects in days, instead of months. Giving you best practices with the most advanced system design/system design for reusing UI components, combined with access to 500+ open-source components that you can build anything with. Yes it’s open source tech with no vendor lock. Which means you can export any part of your UI kit / project at anytime. Our goal isn’t to enhance your tech stack, not to lock you in.…

I've never used .NET, know nothing about .NET or vb, or anything outside vc++ & MFC. Recently I gave GPT a try, guiding it step by step, and asking it to help me rebuild a tool I originally wrote in MFC. To my surprise, it worked: a full Excel-to-PDF automation app, done in 30 minutes; including a small algorithm I thought would be too tricky for AI to handle. I didn't understand even a single line of the code, I just kept asking, copying, and running. It felt amazing… but also terrifying.If AI can do this now, what happens 5 years from now? Here's a 5-min video I made showing the full…

Read an article yesterday about the H.264 codec increasing their licensing fee by an astronomical amount. And as always, my first shot was how hard could it be to try and build a codec which could be that efficient. I've personally been on a drive to improve my ability to one-shot complex features, products, or make even surgical changes. It's been a few months since I've been doing that, and honestly, results have been great for both work and work/life balance. This was a fun experiment. It burned through tokens, but it helped me identify some more improvements I could make to my…

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…

Firstly, I’m not a developer — but I am a very technical, over-50, product person and entrepreneur. This project started shortly after Claude Code launched. I had already worked on a few other AI coding projects, and decided to see how far I could realistically take something end-to-end. While I had some help from a developer, I increasingly felt capable of taking on more work myself. So about 9 months in the making, working full time on it past 2 months. Stack: Postgres, Next.js on Render. Monorepo with both frontend and backend services. Some takeaways from using Claude Code on this…

Hey HN! For that last 8 months I've been trying to make agents that can hack web applications to find vulnerabilities in them - An AI Security Tester. The system has 29 agents in total, a custom LLM Orchestration framework which works on the task-subtask architecture (old-school but works amazingly for my use case, and is pretty reliable) with custom agent calling mechanism. No Auo-Gen, Langchain and Crew AI - Everything custom built for pentesting. Each test runs in an isolated Kali linux environment (on AWS Fargate), where the agents have full access to the environment to undertake any…

The main goal of this was to be able to not just run multiple Claude Code sessions at once, but actually manage them and keep track of what I was doing. Sometimes this is multiple attempts on the same task, sometimes I work several tasks at once. Really I was just sick of twiddling my thumbs waiting for the coding agent to finish, and I wanted it to be easy to work on/review/test another change while I waited.

Hola HN! Long time lurker, sometimes commentor, first time poster here. I’ve been working alongside my two co-founders and a few colleagues on a project I’m excited (and a little nervous) to share with you all! Like many of us, I’ve lived a tortured existence with AI coding (is it vibes?) over the past few months - I think November was a big moment with this. But, one thing I’ve noticed after building orchestration layer after orchestration layer is that the thing I always came back to was “what the hell is Claude Code actually doing?” Perhaps it’s because of the time Claude Code got…

After fine-tuning GPT for a personal project, I realized how tedious it is to write plain text in a massive JSON file. That's why I built this app for my own use, and I want to see if others could benefit from a tool like this as well ;)
