pgvector is a free, open-source PostgreSQL extension that adds vector similarity search to any Postgres database. There is no software cost — pgvector itself is free under the PostgreSQL License. Infrastructure costs depend entirely on how you host Postgres: self-hosting on a $5–$15/month VPS is common for small projects, while cloud-hosted Postgres (Supabase, AWS RDS, Neon) adds its own fees.
