The open-source vector database engineered for billion-scale embedding search and RAG.
Milvus is the battle-tested open-source vector DB behind some of the largest embedding deployments on earth. It supports multiple index types, hybrid search, and ten-billion-scale collections, with a managed Zilliz Cloud for teams that don't want to run it themselves.
Who it's for: Enterprises and platforms building RAG and similarity search at very large scale.
Billions of vectors, distributed.
Dense, sparse, and metadata filters.
Pick the right trade-off per use case.
Fully managed option.
When your vector needs outgrow a starter store, Milvus is the open-source standard. Self-host for control or use Zilliz for convenience.
