Weaviate
An open-source vector database, Weaviate stores objects and vectors and supports vector search.

About Weaviate
Weaviate is described in its repository as an open-source, cloud-native vector database that stores both objects and vectors. It combines vector similarity search with structured filtering, keyword filtering, retrieval-augmented generation (RAG) and reranking in a single query interface. Data can be vectorized automatically at import through integrated models such as OpenAI, Cohere and HuggingFace, or supplied as pre-computed embeddings. Deployment options include Docker, Kubernetes and Weaviate Cloud, with installation docs also covering AWS and GCP; production features mentioned include multi-tenancy, replication and RBAC authorization.
