Eyrie

Eyrie turns your repo into a live architecture map: UI, API, services, data and every outside service, found from the code. Save a file and only what moved updates. Ask questions in plain English and every answer must cite the graph. Coding agents (Claude Code, Codex, Cursor, Copilot, Muse Code) get the same map over MCP to check what an edit could break. 16 languages. Runs on your machine: no account, no telemetry. Free and open source.
