Weaviate

Weaviate is an open-core vector database with hybrid search, vectorizer modules, and graph-like object connections. Supports sophisticated knowledge retrieval patterns. Operators evaluating Weaviate should check embedding/index APIs, persistence and filter semantics, and how retrieval latency shows up under the load that matters for their corridor—not only demo latency. Prefer primary docs and the evidence rows on this page over secondary summaries when deciding adoption order.
