Omnigraph is a lakehouse-native graph database written in Rust that stores versioned graphs on object storage using the Lance format, with Git-style branching, merging, and time travel. It serves as an operational state and coordination layer for agent fleets, combining graph traversal, vector ANN, and full-text retrieval with Reciprocal Rank Fusion in a single query runtime.

Use cases

• build a versioned knowledge graph on S3-compatible object storage
• give AI agents durable, branchable shared memory
• coordinate hundreds of agents writing to one graph without collisions
• combine graph traversal, vector search, and full-text search in one query
• manage graph schema and security policies as code
• review and merge agent data changes like pull requests
• self-host a graph database that never leaves your own storage

When to choose

• you need Git-style branching, diffing, and merging for graph data
• you run multiple agents that must mutate a shared graph safely in parallel
• you want multimodal retrieval (vector + full-text + graph) fused in one runtime
• you require data to stay on your own S3, R2, GCS, or local storage
• you want declarative cluster, schema, and policy configuration with audit trails

When to avoid

• you need a mature, battle-tested graph database like Neo4j for production-critical workloads
• you only need simple key-value or relational storage without graph semantics
• you want a fully managed cloud database with no self-hosting overhead
• you need broad ecosystem tooling and drivers beyond the provided CLI and HTTP API
