Omnigraph
Verdict: Open-source graph database for AI agent memory and company knowledge. Each agent writes on its own branch, every write is checked against a typed schema, and changes reach the shared graph only after a reviewed merge. Data lives as open files in your own S3-compatible storage, with vector, keyword and graph search in one query. Developer tool, not a ready-made app.

Levels show who gets value from it — many tools work for both beginners and experts.
🚀 Getting started: Install the omnigraph CLI with Homebrew or the install script, clone a cookbook such as Company brain, and query it, or connect it to Claude or Cursor through its built-in MCP server.
✅ Good fit if you run several AI agents that need shared, reviewable memory.
⛔ Not for you if you want a no-code note app or a simple vector store.
