Zvec: Alibaba's In-Process Vector Database Goes Open Source

TL;DR

Alibaba releases Zvec, a lightweight open-source vector database built on Proxima that searches billions of vectors in milliseconds without server overhead.

Key Points

  • Searches billions of vectors in milliseconds with production-grade latency
  • In-process library runs directly in applications—no separate servers or infrastructure required
  • Supports both dense and sparse vectors with native multi-vector query support
  • Built on Proxima, Alibaba's battle-tested vector search engine

Why It Matters

Developers building RAG systems, semantic search, or AI applications can now embed high-performance vector search directly into their code without managing separate infrastructure. The in-process design eliminates network latency and operational complexity, making it practical for notebooks, edge devices, and resource-constrained environments where traditional vector databases are overkill.
