What it does

Rea allows founders to inspect and reverse engineer any app down to its binary level, providing clarity on its inner workings.

When to use it
  • •When you need to understand how a competitor's app works internally
  • •When your development team is having trouble debugging a complex issue in your own app
  • •When you're considering acquiring or integrating a third-party app and need to assess its tech
Ready-to-paste prompt
npm run cli -- inspect --app=/path/to/target/app --level=binary
Heads up: Ensure you have Node.js and npm installed on your system, as Rea is built with TypeScript and requires these to run
