SQLite VSS

SQLite fork with native DiskANN vector search, enabling hybrid SQL+vector on production-ready embedded relational infra with ACID. Leverages existing SQLite apps vs dedicated VDBs.

ClickHouse extension for vector similarity search using HNSW indexes, combining analytical SQL queries with ANN in a columnar relational database. Features ACID-like consistency for hybrid workloads on existing ClickHouse infrastructure. More efficient than dedicated VDBs for analytics+vector use cases.

Managed PostgreSQL service with pgvector integration for hybrid SQL+vector search on existing Postgres infrastructure. Provides ACID transactions and enterprise features, offering cost-effective alternative to dedicated vector databases.

DuckDB extension adding HNSW vector similarity search to analytical SQL engine, enabling hybrid queries with ACID-like features on embedded SQL infra. Efficient for local analytics+vector vs dedicated VDBs.

Postgres extension adding HNSW vector search (5-30x faster than pgvector IVFFlat), for hybrid SQL+vector with ACID on existing Postgres. Superior performance vs dedicated VDBs for Postgres users.

Postgres extension for automated embedding gen/sync in hybrid SQL+vector RAG apps with ACID txns on existing infra.
