Re:Zero – Start building from zero
The Wikipedia of how modern software is built.
Turn any public website into 8 evidence-aware Markdown docs — design, architecture, stack & decisions. Browse 430+ analyzed products in the library, or run one CLI command to drop agent-ready context into Claude Code, Cursor & Codex. For learning, not cloning.
👋 Hi Product Hunt! I'm the maker of rezero.md.
Every builder learns by studying products they admire — but "view source" gives you minified noise, and screenshots give you nothing your AI coding agent can actually use. So most people end up cloning a UI without understanding the decisions behind it.
rezero.md turns any public website into structured, evidence-aware documentation. Point it at a URL and it generates 8 Markdown docs: DESIGN · IA · COMPONENTS · STACK_GUESS · ARCHITECTURE · DECISIONS · BUILD_WITH_THIS · SITEMAP.
The thing I care about most: it's honest about what it knows. Every doc separates observation (what's actually on the page) from inference (a labeled, confidence-rated guess) from recommendation (transferable patterns). It never reproduces source code or protected assets — this is for learning, not cloning.
Two ways to use it:
🌐 Browse the library — 430+ products already analyzed (Vercel, Stripe, Linear, Notion, Figma…), free to read at https://www.rezero.md
⌨️ Run it in your terminal — npx rezero-md init https://example.com writes the docs into .rezero/, instantly readable by Claude Code, Cursor, Codex & Gemini CLI. No plugin, no extension, runs locally.
It's free, and the library is available in 7 languages.
I'd love your feedback — which product should I analyze next? Drop a URL below and I'll add it. 🙏
