Neon is a serverless Postgres database with unique features like database branching (like git for your database), autoscaling to zero, and instant point-in-time restore. The default Postgres choice for serverless architectures.
Reviewer scorecard
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“Database branching is a killer feature — branch your DB for every PR, test with real data, merge back. Transformed how we handle database migrations.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Scale-to-zero means you actually pay nothing when idle. The cold start is noticeable (~500ms) but acceptable. For serverless apps, Neon is the obvious choice.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
“Neon is making Postgres behave like a serverless primitive. The branching model will become standard — in 3 years, we'll wonder how we ever managed databases without it.”
