Weaviate
Open-source with built-in hybrid search and a module ecosystem.
87
sovereigntyWeaviate is an open-source (BSD-3-Clause), cloud-native vector database that stores objects and vectors together, pairing similarity search with structured filtering and strong built-in hybrid (keyword + vector) search. Its module system can handle embedding generation for you, and Weaviate Cloud offers the managed path. A polished middle ground between Qdrant's lean engine and Milvus's heavy distribution.
