Open-source developer tool

Graphy

Turn a folder of code into a queryable knowledge graph. Fast, plugin-driven, ships as a single binary.

What it does One command, three outputs Run graphy . in any repo. It scans the code and writes a bundle to graphy-out/ you can read, share, or feed to an agent.

graph.json full nodes + edges, machine-readable

GRAPH_REPORT.md god nodes, community count, ambiguous edges

graph.html interactive viewer — pan, zoom, click to highlight neighbours

Built for speed

37 Languages

3ms Warm cache

1 Rust binary

Best-of-five on a 54-file mixed-language repo. Single files land in 2–4 ms cold; cache hits flatten to 3 ms regardless of language.

Claude Code / MCP Your agent queries the graph, not grep Graphy runs as an MCP server, so a coding agent looks code up in the graph instead of reading files blindly. It exposes five tools:

search_labelneighborsquery_nodeshortest_pathstats

/plugin marketplace add DeveloperBeau/graphy
/plugin install graphy@graphy
