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. If you know someone who has done the same, one person, 500k lines, documented proof, please write their name in the comments.

WOZCODE▲194For the last year we've been building an AI mobile app builder. Last week we decided to generalize our agent harness and benchmark it against vanilla Claude Code. Turns out the tools we built for app building were significantly more efficient than the native Claude Code tools. When we ran benchmarks we beat Claude code on speed (~40% faster) , cost (25-55% cheaper) and performance (+17% on Terminal Bench 2.0). Today we're making our agent harness publicly available as a Claude Code plugin. Use code WOZCODE1 to try it for $1 at wozcode.com

FoundersWall▲35I used to be just a blogger. Now I build internet products, still without code, using AI, design, and taste. I was building in public on X for last 2 months. And honestly, I got tired of how it became performative and started to feel fake. I shipped 2 products. Both failed to get any real traction. I kept sneaking into popular builders’ profiles, hoping to learn how they do it. One thing I kept seeing everywhere, product launch directories. I thought here is the scope. So I started building one. Same UI like the rest. Nothing special. Suddenly one day when it was half built, I realized…

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

I am a non-hacker "idea guy" with zero discernible talent. Like most, the story starts with me doing things the hard way. I dreamt of a tool that would save me countless hours. Like most of my ideas, it was supposed to die in a couple of hours, but this one had some legs.... "If I needed this, surely others did too" kept looping in my head. Could I get this built? Could I build it myself? Nah...too lazy to learn how, but before I did anything, I had to promise myself one thing: No more ideas! If ideas were sit-ups, I would have a six pack instead of this tire. It was a constant mental…

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…

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…

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.

A little over a week ago, I was wondering if anyone would care about the thing I’d just built. Let me rewind a bit. I’m a solo indie maker, just like a lot of you. I’ve built so many projects, put in the work, and then… nothing. A few months ago, I launched something I was genuinely proud of on one of the big platforms. I was excited, hopeful. But within hours, it got buried under a pile of other launches. No one saw it. No one cared. That sucked. Not because I expected it to blow up overnight, but because it felt like I never even had a shot. And I kept thinking about how many other indie…

After getting impatient with a "SwiftUI for Designers" course I decided to fuck around and find out. Just hours after asking my 1st question: "Are you familiar with SwiftUI?" the core functionality of this app (an exercise utility) was up and working. I've spent the past week tweaking the UI with small animations and features. It's a humble tool (local storage only) but I am nonetheless floored with how GPT has allowed me to completely skip the "learning syntax" part of development and ship something that I actually use. Not only did it lower the syntax bar virtually to 0... I've learned…

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 : -…

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…
