About Omnigraph

Omnigraph is an open-source graph database for building connected knowledge stores and durable AI agent memory. It combines graph traversal, vector search, and full-text retrieval, letting applications find relevant information and follow the relationships around it in one query. Typed schemas define the entities, links, and constraints that every write must satisfy.

Teams can give each agent or task a separate branch, inspect proposed changes, and merge approved work into a shared graph. Version history supports reviewing earlier states, while the Studio desktop app provides a visual workspace for exploring records and reviewing changes. Developers can run Omnigraph locally or on their own infrastructure, with data stored in open Lance files. The engine is free under the MIT license; the hosted Cloud service remains in private preview.
