Serverless Postgres with branching, autoscaling, and a native pgvector layer used as a default RAG database for AI apps.
Neon is a serverless Postgres platform that has become a popular database choice for AI-first apps and agent backends. The architecture separates storage from compute, so databases can scale to zero when idle and instantly resume on the next query, which dramatically lowers the cost of running many small databases. Database branching forks a full production database in seconds for preview deployments, integration tests, or per-agent scratch space. For AI use cases, Neon ships pgvector with HNSW for fast ANN, plus integrations with LangChain, LlamaIndex, and OpenAI so RAG pipelines can use Postgres as both relational and vector store. Free, Launch ($19/mo), Scale ($69/mo), and custom Business/Enterprise plans are available. Databricks acquired Neon in 2025.
