memista explores whether you need a dedicated vector database or whether SQLite-backed approximate nearest neighbour search in pure Rust can serve the same purpose. It studies the performance characteristics and accuracy trade-offs of lightweight embedded vector search.
Embedded ANN vector search backed by SQLite in pure Rust — no separate service to deploy.
memista is one option in a category that includes Pinecone, Qdrant, Weaviate, Milvus, Chroma , and SQLite-vss. Our Compare page has the full side-by-side.
