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
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Database branching is a killer feature — branch your DB for every PR, test with real data, merge back. Transformed how we handle database migrations.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“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.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
“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.”
