See how any app works without its source code: set up REA (Reverse Engineer Anything) with your AI agent in one command, then paste a prompt

The companion to the REA reel. REA is a free, MIT-licensed tool that plugs into Claude Code, Codex, Cursor, Gemini CLI and other agents so they can inspect an app, trace a feature with evidence and build your own version. PAGE 1 — the 3-step flow: set up, ask, read the evidence. PAGE 2 — setup in about 5 minutes: the Node.js versions you need, npx rea-agents setup, the agents it configures, when you need Hopper or Ghidra, and how to update. PAGE 3 — five copy-paste prompts, eight things REA can look at (apps, websites, binaries, .NET, Android and more) and three real case studies, including a DX-Ball rebuild that passes 3,205 original tests. PAGE 4 — the responsible-use rules from the project itself: only on apps you own or are allowed to analyze, build your own version, never copy. Every fact read from the official morluto/rea repo on October 31, 2026 (version 6.8.0). Independent guide from Hyperautomation Labs — not affiliated with REA or its authors.
