sqlite-vec
A tiny vector search extension for SQLite, written in C with no dependencies, so it runs anywhere SQLite does, from a server to a phone. A neat fit when you want vector search inside an existing SQLite database with no extra service.
Strengths
- Runs everywhere SQLite does, with no separate database to operate
- No dependencies, and trivial to embed in an application
- Permissively licensed and genuinely lightweight
Weaknesses
- Aimed at small to medium collections, not massive scale
- Fewer features than a dedicated vector database
- Vector search in SQLite is newer and still maturing
