Understand Anything

Best for: developers joining an unfamiliar codebase who need a map of it before they can contribute safely.

Understand Anything, an open-source project from Egonex originally created by Lum1104, turns any codebase, knowledge base or set of docs into an interactive knowledge graph you can explore, search and ask questions about. It works with Claude Code, Codex, Cursor, Copilot and Gemini CLI, and is MIT licensed.

What makes it useful: the framing — "graphs that teach, not graphs that impress" — is the right one. Plenty of tools generate visually striking dependency diagrams that answer no actual question. This one targets the concrete problem of joining a team with 200,000 lines of unfamiliar code and not knowing where to start, so the graph is built to be interrogated rather than admired.

Where it falls short: graph quality depends on how well the codebase's structure reflects its actual behaviour — heavy dynamic dispatch, reflection or metaprogramming will produce a less faithful map. It also expects a supported coding agent to be installed and configured, which means API costs.
