HydraDB OSS

Graph database built on object storage for agent memory and context

Object-storage-native engine

Graph, WAL, value, and index data all live in S3-compatible storage with a hot/warm/cold tiering strategy, cutting infrastructure cost dramatically versus memory-resident graph databases.

Unified retrieval layer

One query can traverse graph relationships and run vector, BM25, and reranked search together, so agents do not have to orchestrate four separate systems.

Temporal versioning and memory

Every change is tracked, letting agents recall what happened, when, and in what sequence, which supports auditability and long-running agent workflows.

Neo4j-compatible interfaces

OpenCypher over Bolt plus an HTTP API and SDKs make it approachable for teams already familiar with property graphs.
