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 Parry — a 2-minute daily puzzle about catching AI's mistakes: spot the planted flaw, catch the answer that's lying to you I have been recently fascinated with puzzles as a way to help improve my BS-radar when using AI. I designed Parry to help with this - One puzzle a day - find the one flaw hidden in a confident paragraph, pick which of two AI answers actually helps you (one is subtly useless), call a claim true/false. Free, no account, nothing you input leaves your devi
