About this API

Neon is a serverless Postgres database company founded 2021; team mostly former Postgres core developers. Differentiating tech: completely separate storage from compute — storage on S3 (proprietary filesystem), compute is stateless PG instances. Architecture enables two magics: (1) Scale-to-zero — idle compute auto-stops, $0 cost, 1-3s to restart on next connection; (2) DB branching — each branch is storage copy-on-write, creates "copy" of multi-GB data in seconds. These features make Neon perfect for Vercel / Netlify / Cloudflare Workers serverless + preview deployments — each PR gets staging DB, auto-destroyed after merge. Vercel Postgres backend is Neon. Generous free tier (10 projects), top Postgres choice for personal / hobby projects.

Strengths & limitations

Strengths

  • Scale-to-zero (5 min idle auto-stops compute, $0)
  • DB branching (each git branch own DB copy created in seconds)
  • 100% Postgres compatibility (any PG tool works)
  • Generous free tier (10 projects + 3GB storage)

Limitations

  • Scale-to-zero cold start (new connection 1-3s)
  • Some Postgres extensions unsupported
  • Relatively young (founded 2021)

FAQ

Neon vs. Supabase?+

Just Postgres + serverless architecture: Neon (lighter). Want BaaS full-stack (auth + storage): Supabase.

Does cold start affect production?+

Only after 5 min idle. Production apps with frequent access keep connection warm.
