Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.
What it is
Neon is an open-source serverless Postgres database platform. It separates storage and compute and substitutes the PostgreSQL storage layer by redistributing data across a cluster of nodes. Try the Neon Free Tier to create a serverless Postgres instance. Then connect to it with your preferred Postgres client (psql, dbeaver, etc) or use the online SQL Editor. See Connect from any application for connection instructions.
When to use it
Reach for neon when your app needs to store, query, cache or sync data — it's written in Rust and fits stacks tagged database, postgres, serverless.
