About codegraph
CodeGraph is a pre indexed code knowledge graph that runs locally and wires into AI coding agents — Claude Code, Cursor, Codex, Gemini, OpenCode, AntiGravity, Kiro, GitHub Copilot, and Hermes Agent — so those agents query a semantic map of the codebase instead of reading files one at a time.
