pgvector is an open-source PostgreSQL extension that adds vector data types and similarity-search indexes directly to a Postgres database, rather than being a standalone service. It targets developers who want vector search inside the Postgres they already run, supporting hybrid search by combining vector queries with SQL and full-text features. It is open-source under the PostgreSQL License and free, with the only cost being the Postgres host it runs on. Because it is an extension, it is self-hostable and runs anywhere Postgres runs (managed services or self-managed), and is not itself a managed service. The record lists no formal compliance certifications.
