SQLite-Vector is a cross-platform SQLite extension for fast vector search in ordinary tables, storing embeddings as BLOBs with quantization, SIMD acceleration, and a low default memory profile. It targets embedded, mobile, and edge AI apps that need semantic search without a separate vector server.
Developers building local-first or embedded RAG, recommendations, and agent memory on SQLite without external vector databases.
Hosted SQLite Cloud plans on sqlite.ai are separate platform pricing, not monthly fees for the open extension.
SQLite-Vector adds semantic nearest-neighbor search directly inside SQLite for edge and offline AI workloads.
