sqlite-vec

https://github.com/asg017/sqlite-vec

An extremely small, "fast enough" vector search SQLite extension that runs anywhere! A successor to sqlite-vss

• Store and query float, int8, and binary vectors in vec0 virtual tables
• Written in pure C, no dependencies, runs anywhere SQLite runs (Linux/MacOS/Windows, in the browser with WASM, Raspberry Pis, etc.)
• Pre-filter vectors with rowid IN (...) subqueries
