# sqlite-vec

> sqlite-vec is a Rust-based SQLite extension library for vector similarity search using diskANN indexes on embeddings, enabling lightweight ANN without separate databases. Features HNSW-like graphs, quantization support, and hybrid full-text+vector queries in embedded SQLite environments. Perfect for prototyping and on-device apps; extremely lightweight compared to Milvus, more persistent than pure hnswlib.
