Chroma is Open-source embedding database designed for simplicity — the default vector store for many RAG prototypes.. sqlite-vec is A single-file SQLite extension for vector search — exact brute-force KNN that lives inside the database you already ship..
Chroma has more — ★ 29k vs ★ 8.0k (live counts).
Often yes — many teams combine vector databases. Check each tool's docs for interop; they solve overlapping but not identical problems.
Chroma is primarily Rust; sqlite-vec is primarily C.
