Tech Stack & Architecture
What is the best database for an AI-powered product in 2026?
Answer:
PostgreSQL with the pgvector extension remains the top choice for most AI-powered products in 2026, combining relational data handling with vector similarity search within a single system. For products with high embedding and retrieval needs, Pinecone or Weaviate offer specialised vector database features. Supabase (built on PostgreSQL + pgvector) provides the quickest route to production for AI-driven MVPs.
