CodeGraph Cuts Claude Code Costs by 35% With Pre-Indexed Knowledge Graphs

CodeGraph is an open-source tool that builds a pre-indexed knowledge graph of your codebase, letting AI coding agents like Claude Code, Cursor, Codex CLI, and Hermes Agent query symbol relationships and call graphs instantly — instead of scanning files with grep and glob on every request.

Benchmarks across 7 real-world codebases in 7 languages show average savings of 35% on cost, 59% fewer tokens, 70% fewer tool calls, and 49% faster responses. The tool runs 100% locally via an MCP server, requires no Node.js to install, and auto-configures supported agents with a single interactive command.

We’re always testing new tools that push the limits of AI-assisted development — and a project sitting at nearly 15K GitHub stars isn’t something you walk past. CodeGraph can index routes, map call graphs, trace callers and callees, and assess edit impact before a single file is touched.
