pgvector

pgvector/pgvector · ★ 23.5K

pgvector is an open-source extension that adds vector similarity search to Postgres, so embeddings are stored and queried right next to your relational data. It supports exact and approximate nearest neighbor search.

lancedb

lancedb/lancedb · ★ 11.8K

LanceDB is an open-source vector database for multimodal AI: a central platform where you store, index and search petabytes of vectors and multimodal data, built for fast, production-ready retrieval.

weaviate

weaviate/weaviate · ★ 16.9K

Weaviate is an open-source, cloud-native vector database: it stores objects and vectors together and lets you combine vector search with structured filtering for semantic search at scale.

pg_vectorsearch

timescale/pg_vectorsearch · ★ 409

pgvectorsearch is a PostgreSQL extension that adds the PRISM index, a high-performance approximate nearest neighbor (ANN) search method for vector data, built to outrun pgvector's IVFFlat and HNSW indexes at large scale.
