Pricing Analysis

Overview

pgvector is an open-source PostgreSQL extension - completely free. You pay only for the PostgreSQL hosting (from $5/month on Supabase or RDS). It's an extension, not a standalone database. Performance caps out well below dedicated vector DBs at billions of vectors.

Which Plan Is Right for You?

$undefined/undefined

Free extension, add to any PostgreSQL instance. The obvious first choice for teams already running Postgres. Handles most RAG use cases up to a few million vectors without additional cost.

Our Verdict

Zero added cost if you're already running PostgreSQL. For under 1M vectors, pgvector on a $20/month Postgres instance beats paying for Pinecone. Over 10M vectors with high QPS, dedicated vector databases win on performance.
