How to Choose a Vector Databases Tool
Key criteria to evaluate when comparing Vector Databases solutions:
About Chroma
Chroma is an open-source embedding database designed for simplicity and developer experience. It provides a lightweight, easy-to-use API for storing, querying, and filtering embeddings locally or in the cloud. Chroma is the default vector store in many LLM frameworks like LangChain and LlamaIndex, making it extremely popular for prototyping and building RAG applications quickly.
About Milvus
Milvus is an open-source vector database built for scalable similarity search, capable of handling billions of vectors. Backed by the Zilliz company, Milvus supports multiple index types (IVF, HNSW, DiskANN), GPU-accelerated search, and multi-tenancy. Zilliz Cloud offers a fully managed version with automatic scaling. Milvus is widely used in enterprise deployments requiring high-throughput vector search at scale.
