repo-scan
Every ecosystem has its own dependency manager, but no tool looks across C++, Android, iOS, and Web to tell you: how much code is actually yours, what's third-party, and what's dead weight.
When to Use
- Taking over a large legacy codebase and need a structural overview
- Before major refactoring — identify what's core, what's duplicate, what's dead
- Auditing third-party dependencies embedded directly in source (not declared in package managers)
- Preparing architecture decision records for monorepo reorganization
