Reading a complex codebase blind is officially a thing of the past.
Someone just open-sourced a tool called "Understand Anything" that scans your entire repository, maps out a visual knowledge graph of every single file/function, and serves it up on an interactive dashboard.
How it actually works:
- Just run /understand to let 5 specialized AI agents rip through your code
- Turns files, functions, and classes into visual, clickable nodes
- Ask questions in plain English like "which parts handle auth" to find code instantly
- Diff impact analysis shows exactly what your changes will break before you commit
It's open-source, supports Claude Code, Cursor, and Gemini CLI, and is already trending at #1 on GitHub. Bookmark this for your next legacy project.
