Best Vector Databases for AI Apps

Vector databases for retrieval-augmented generation (RAG), semantic search and recommendation systems. Pinecone is the simplest fully managed option for production, Weaviate combines vector and hybrid keyword search with built-in modules, and Qdrant is a fast open-source engine with strong filtering. Milvus scales to very large datasets in self-hosted and managed form, and Chroma is the quickest way to prototype embeddings locally in Python.
