zvec

Zvec is an open-source, in-process vector database developed by Alibaba. Lightweight and lightning-fast, it embeds directly into applications without requiring external servers. Battle-tested at scale, Zvec supports dense and sparse vectors, native full-text search (FTS), and structured scalar filters, enabling seamless hybrid retrieval in a single query. Featuring a DiskANN index to drastically cut memory usage for large datasets and Write-Ahead Logging (WAL) for durability, Zvec runs efficiently across edge devices, servers, and desktops with official SDKs for Python, Node.js, Go, Rust, and Flutter.
