AI-powered security auditor that scans GitHub repos to find vulnerabilities and suggest fixes.
u/uwais_ish · Reddit
Three weeks to build an AI security scanner. The scanner was the easy part. Shipped RedFlag this month. Breakdown of where the time actually went, because it was nothing like I estimated. Stack: Next.js 16, Auth.js v5, MongoDB, Stripe, OpenAI. Deployed on Vercel. What I thought would be hard: getting an LLM to find real vulnerabilities. What was actually hard: getting it to stop finding fake ones. First working version flagged 200+ issues on a clean repo. Every one plausible, most of th

I built a coding platform where you can compete with Claude on various coding problems, it evaluates based on speed, correctness and code quality Link: https://www.duelai.dev/ Feel free to give it a try and let me know what you think! submitted by /u/Easy-Visit-3934 to r/SideProject [link] [comments]

AI-powered code review that runs code in microVMs to catch more bugs.
u/dumbfoundded · Reddit
Ito, AI Code Review that Runs Code I've been using AI code review tools but none of them actually run code so I built one: https://www.ito.ai/ The way it works is that it uses microVMs to spin up your environment with all of the services running. Then a bunch of AI agents go and test the application to collect runtime evidence. The result is you get test cases along with evidence about whether or not the test cases pass or fail. The runtime evidence can be videos, request/response curls, db

Not a direct answer but the guys at Exercism (non-profit that publishes really good and free programming language self-study courses) recently launched a separate site to teach junior programmers both vibe coding and software engineering fundamentals.

Solve daily coding challenges with AI assistance and track your developer streak.

I built this because AI was making me a dumb&lazy engineer I noticed something sad about how I use AI. I was shipping faster, but practicing less. I could get answers quickly, but I was losing the habit of working through the fundamentals myself. So I built Unrot: short daily challenges for developers across languages, system design, architecture, data engineering, and other tracks. Game/xp and rewards system, a tiny bit competitive. No signup required to try it: https://unrot.dev

Complete security quizzes across 5 levels to prove your code understanding.

I vibe-coded an anti-vibe-coding app. Yes. I used AI to build a whole academy that trains you to stop blindly shipping AI code. Five levels. Security quizzes. Badges. A streak. The whole “read the error before you panic” curriculum. It’s like building a gym while eating pizza on the treadmill. Play it here → https://videcodingacademy.web.app This post was also vibe-coded.
