Pinecone is the most widely used managed vector database, purpose-built for similarity search and retrieval-augmented generation (RAG). It offers serverless and pod-based architectures, supporting billions of vectors with single-digit millisecond query latency. Pinecone provides metadata filtering, namespaces, and hybrid search combining dense and sparse vectors. Its managed service eliminates infrastructure complexity, making it the go-to choice for teams building semantic search, recommendation engines, and RAG-powered AI applications.
Vespa is an open-source search and recommendation engine combining vector search, full-text search, and structured queries.
