AI scans competitors and market data to validate if a startup idea is worth building in 90 seconds.

Most founders skip validation and pray. I automated the "worth building?" check. AI scans competitors, Reddit, and market data → Cook or Kill in 90 seconds. Killed? It surfaces the pivot the data actually backs.

Practice system design by submitting architectures and experiencing AI-triggered production incidents.
u/No-Preference-846 · Reddit
I built an AI-augmented system design practice tool that triggers a live production incident when you submit your design - not just a critique Every system design prep resource I used was static — read a diagram, read the tradeoffs, move to the next one. Nothing ever pushed back on what I actually built. So I built ChaosBench . You design a system on a canvas — drag components, wire them up — and when you submit it, an LLM (Gemini) finds the actual weak point in your specific design and

Play a free online tile-pattern game with friends or solo against the computer.

A couple weeks ago we were on vacation with friends, and after the kids were asleep we played games -- mostly Qwirkle, which I had never played and am terrible at. I don't care about being terrible at games, so I made a web version to keep playing after vacation: build lines of tiles that share a color or a shape, 2-4 players (or add bots). I wanted it to be low friction, so there are no accounts. Your identity is an anonymous id in localStorage, and you can move it to another device by scanning a QR code or hitting a unique url. Start a game and text someone the link (game slugs are semi-memorable three word phrases), or "Play the computer" and you can play immediately against bots. Games are async-friendly with web push for turn notifications. The stack is one Node process on a small VM, Next.js + Socket.IO, no database. The server and the client use the same engine so moves validate optimistically, and the bots go through the same functions, so bot moves are always legal. State is

Interactive platform for learning data structures and algorithms with 300+ problems and visualizations.

I spent a year building a DSA learning platform with 111 interactive visualizers. Would love feedback. A few years ago, I failed interviews at Google, Amazon, and Microsoft. The reason was simple: I could code, but I never properly understood Data Structures and Algorithms. I spent almost a year learning DSA after that. During that time, I realized I don't learn by memorizing. I learn by building. And I couldn't find a tool that taught DSA the way I wanted to learn it. So I
