Engineering OS

Engineering OS is a local-first tool that gives AI code editors like Claude Code, Cursor, and Codex persistent knowledge of your project. Instead of re-explaining architecture each session, the system indexes your codebase, builds a dependency graph, and serves that context to any MCP-compatible AI editor. It runs entirely on your machine with no cloud accounts required.

The tool handles code search with instant results, tracks architectural decisions to avoid re-debating, learns from discovered gotchas, enforces conventions, and scans for security issues. Installation takes two minutes: point it at your project, and your AI immediately has access to cross-repo topology, past decisions, and indexed code patterns.
