pgvector adds vector similarity search to PostgreSQL for semantic search, recommendations, and retrieval-augmented generation. Developers can use familiar SQL and PostgreSQL operations while keeping embeddings close to application data, reducing the need to run a separate vector database for every use case.
A well-built tool that delivers consistent value. The interface is clean, performance is snappy, and our operational workflows run smoothly.
SingleStore provides a straightforward, dependable solution that integrated smoothly into our operational stack. Uptime is consistent and user adoption across the team was immediate.
We have been using SingleStore across our departments and appreciate the simplicity and stability of the system. It handles core workflows without unnecessary bloat.
