Neon
Overview
Serverless Postgres with instant branching, autoscaling, and a built-in AI Gateway — the backend infrastructure layer built for AI-native apps and agents.
Full Description
Neon is a serverless PostgreSQL platform designed from the ground up for modern AI-driven applications and autonomous agents. It separates compute from storage, enabling instant database branching — meaning you can spin up a full copy of your production database in seconds for development, testing, or AI agent sandboxing. Neon autoscales to zero when idle and scales instantly under load, making it cost-effective for both development and high-traffic production workloads. Beyond core Postgres, Neon bundles Auth, serverless Functions, Object Storage, and an AI Gateway that provides a unified interface to multiple LLM providers with built-in caching, rate limiting, and observability. The platform is popular in the AI developer community for its seamless integration with frameworks like LangChain, LlamaIndex, and Drizzle ORM, and its native support for pgvector enables vector similarity search directly inside Postgres without a separate vector database. Neon's branching model is particularly powerful for AI agent workflows that need isolated, stateful database environments per session or task.
