What is the best vector database for RAG applications in 2026?
Answer:
Pinecone, Weaviate, and pgvector are the leading vector databases for RAG (Retrieval-Augmented Generation) applications in 2026. Pinecone provides the most straightforward managed setup for production workloads. Weaviate is suitable for teams requiring hybrid keyword and vector search. pgvector, available via Supabase or standalone PostgreSQL, is the best choice for teams that want vector search integrated into an existing relational database without additional infrastructure.
