Closed Source Is No Longer a Moat (REA Explained)

Checkout TestSprite - https://switchdim.s.gy/testsprite REA (Reverse Engineer Anything) is the fastest-rising repo on GitHub: an open-source MCP server that lets coding agents like Claude Code, Cursor and Codex look inside apps they have no source code for. In this video I show what it actually does (and what it doesn't), build a Mac app with a hidden unlock code, strip out every name, and watch my agent recover the rules from the compiled binary (then check it against the real source), and explain why closed source is no longer much of a moat. Plus the legal and security catches you need to know first. This video is sponsored by TestSprite — an AI testing agent that writes end-to-end tests, runs them on your live app, and hands failures back to your coding agent to fix.
