4—Iinfiniflow / infinityThe AI-native database built for LLM applications, providing incredibly fast hybrid search of dense vector, sparse vector, tensor (multi-vector), and full-text.C++Apache-2.0 · PermissiveInsufficient rank history4,755458——2026-11-02
5—Ooceanbase / seekdbAuthor description: The AI-Native Search Database. Best for agent storage, it unifies vector, text, structured, and semi-structured data into a single engine. This all-in-one database makes agents smarter, easier to run, and more stable.C++Apache-2.0 · PermissiveInsufficient rank history3,2221,205——2026-11-02
6—Oorneryd / NornicDBNornicdb is a distributed low-latency, Graph+Vector, Temporal MVCC with all sub-ms HNSW search, graph traversal, and writes. Using Neo4j Bolt/Cypher and qdrant's gRPC means you can switch with no changes while adding intelligent features like schemas, managed embeddings, reranking+llm, GPU accel, Auto-TLP, Policy-based Memory Decay, and MCP server.GoMIT · PermissiveInsufficient rank history92356——2026-11-02
