Pricing notes

As of 2026-09-14: DuckDB is free MIT/open-source (local/embedded). Vector similarity via VSS + community extensions — not a hosted vector SaaS. MotherDuck is the hosted DuckDB warehouse (Lite $0 with 10 GB + 10 Pulse hrs; Business $250/org/mo + usage). Treat DuckDB as local OLAP + light vector for agent analytics, not a Pinecone replacement.
