Vector databases compared — pick the retrieval layer for your RAG

Pinecone, Weaviate, Qdrant, Chroma, Milvus, LanceDB, Turbopuffer. Neutral blurbs and official links to compare throughput, filtering, and hosting shape.

Shortlist for queries like “best vector database 2026”, “Pinecone vs Qdrant”, or “self-hosted RAG”. Differences land on throughput, recall with filters, metadata model, multi-tenancy, and whether you run serverless or self-hosted. This is a neutral launch pad—always confirm pricing, backups, and region hosting on each vendor’s docs before committing.
