PostgreSQL License — permissive. Scale ceiling lands in the low millions of rows.
About.
pgvector adds embeddings and ANN indexes to the Postgres you already run, so similarity search joins your SQL instead of living in a second system. The PostgreSQL License is permissive like MIT. One database, one backup, one bill.
Postgres extension · HNSW and IVFFlat indexes · SQL queries · any Postgres data type
