Detailed Review of HelixDB - Other AI Software (2026)

What is HelixDB?

HelixDB is an open-source graph-vector database for AI memory: a property graph with native vector and full-text search in one Rust engine on object storage, for agent memory, RAG, and company brains. HelixDB is the database for all knowledge work. Built for agents, affordable at any scale. Pick an industry to see the records HelixDB links and the question one request answers: traverse to the records that matter, then search only those. How do I use HelixDB for agent memory? Store memories as nodes with indexed properties for tenant and lifecycle fields, such as isLatest or expiresAt, and use edges for provenance, entities, and version history. To recall, traverse to the memories an agent is allowed to see, then run vector and BM25 search inside that
