4.5 / 5.0

Neon is a serverless Postgres database built for AI applications, with branching features that enable each pull request or AI agent to have its own isolated database branch. Its pgvector support makes it a popular choice for RAG applications, while its serverless architecture scales to zero and instant provisioning enable AI agent use cases where databases are created and destroyed flexibleally.
