CodeGraph: Local Knowledge Graph Stops Claude Code from Re-reading Files
thisguyknowsai · x · 2026-08-25
Colby McHenry built CodeGraph, a local knowledge graph designed to stop AI coding agents like Claude Code from re-reading files. It uses a local SQLite database and a native Rust kernel to parse code, supporting 20+ languages. Instead of looping through repos with grep and glob, the agent queries the graph to get exact sources, call paths, and change blast radii instantly. It auto-syncs on save, is 100% local with no API keys, and works with Claude Code, Cursor, Copilot, and others. Benchmarks from YC across 7 open-source repos demonstrate significant performance gains.
