Milvus is a high-performance, cloud-native vector database built for scalable vector ANN search
OSS
Milvus
Added 1 June 2026
Overview
Milvus is an open-source vector database written in Go that performs approximate nearest neighbor (ANN) search at scale. It handles high-dimensional vector indexing and retrieval for applications like semantic search, recommendation systems, and similarity matching. Designed for cloud-native deployment, it supports distributed architectures and multiple index types.
Best for
Best for
Teams building search or recommendation features who need to manage vector data at scale and prefer open-source control over managed services.
Use cases
- Semantic search over embeddings from LLMs
- Recommendation engines based on vector similarity
- Image or document retrieval by learned representations
