GitNexus
Code knowledge graph for AI coding agents: it parses a codebase with Tree-sitter, resolves imports and call chains, clusters the architecture and traces the blast radius of a change, and serves the result to Claude Code, Cursor, Codex and other agents over seven MCP tools; free noncommercial open-source engine, $29 a seat managed SaaS, and a custom self-hosted or air-gapped tier. Benchmark figures on the pages are the company's own.
