Milvus
Open-source vector database for large-scale similarity search and RAG systems.
Milvus fits engineering teams building larger retrieval, embedding search, recommendation, or RAG systems that need an open-source vector database, high-scale indexing options, and a path to managed Zilliz Cloud if operations outgrow self-hosting.
Qidao take
Milvus is strongest for large RAG stores. It is a weaker fit for tiny prototypes needing the simplest setup.
Qidao fit index: 83/100
This is a Qidao method score for workflow fit, decision clarity, alternatives, risk, and practical use. It is not a user rating, paid placement, or benchmark claim.
