Understand-Anything

Understand-Anything turns an undocumented, tangled codebase into an interactive knowledge graph you can actually explore. It maps your entire codebase into a visual graph of components, relationships, and data flows, then lets you search and ask questions about it.

It works as a set of Claude Code skills, so you install it and run it from your terminal. Point it at any repo and it generates a navigable map of the architecture. The graph is interactive: click a node, see what it connects to, ask 'how does data flow from X to Y.'. MIT licensed, completely free. No hosting needed. It runs locally and generates a web dashboard you open in your browser.

The catch: the quality of the knowledge graph depends heavily on how well-structured the codebase is. Messy repos with circular dependencies produce messy graphs. And it's Claude Code-specific. If you're in Cursor or Codex, this won't help you.
