Neon

Neon is the serverless PostgreSQL platform: we deliver instant autoscaling, scale-to-zero, and Git-like database branching for modern, cost-efficient development workflows.

You need a database that keeps pace with modern development, and Neon delivers. We've separated storage and compute for PostgreSQL, enabling true serverless functionality: your database scales down to zero when idle, saving you money, and instantly scales up under load (autoscaling). Crucially, Neon introduces Git-like database branching (e.g., for staging or feature development), allowing developers to create a full, isolated copy of production in seconds for testing. This architecture provides high availability, bottomless storage, and a robust feature set, including native integrations with platforms like Azure and support for extensions like PostGIS.
