Rea Faang

Rea Faang is a product catalog and CLI tool that provides research and markdown skills for coding agents to build replica products.

Rea Faang catalogs products from major technology companies to help you build them with a coding agent. It brings together public product information, research dossiers, and open-source project candidates so your agent has useful starting points. You choose a product from the catalog, give its markdown skill to your coding agent, and plan, build, and test a scoped implementation. The published npm package bundles the catalog, research, and CLI without requiring a repository clone. It is MIT-licensed and designed for clean-room implementations using public documentation and independently developed code.
