Scope
A backend platform: Postgres + Auth + Storage + Realtime + Edge Functions + auto APIs.
A database: serverless Postgres with developer-grade tooling.
Both give you managed Postgres. Supabase wraps it in a full backend platform (auth, storage, realtime, auto-generated APIs, edge functions) so you can build an app without a separate backend. Neon focuses on the database itself, with serverless separation of storage and compute, instant branching, and scale-to-zero that makes per-PR database previews trivial. Pick Supabase for an all-in-one app backend; Neon when you want a best-in-class serverless Postgres under your own stack.
Supabase is a platform that happens to run on Postgres; Neon is Postgres, re-architected for serverless. If you want batteries-included (auth/storage/realtime) reach for Supabase. If you already have your stack and want elastic, branchable Postgres, reach for Neon.
A backend platform: Postgres + Auth + Storage + Realtime + Edge Functions + auto APIs.
A database: serverless Postgres with developer-grade tooling.
Branching exists but is newer/coarser.
Instant copy-on-write branches are the headline feature.
Always-on compute tiers.
Separated storage/compute with scale-to-zero.
PostgREST REST + GraphQL + client SDKs generated from schema.
None; you build your own API layer.
Built-in auth, RLS integration, object storage.
Not included; use a separate auth/storage provider.
Self-hostable stack; some platform coupling.
Standard Postgres wire protocol; easy to move.
A solo dev or small team shipping an app fast
Auth, storage, realtime, and APIs out of the box save weeks.
CI that needs a fresh database per pull request
Branch the DB instantly, throw it away after the run.
A bursty workload that idles overnight
Scale-to-zero means you stop paying for idle compute.
You already have a backend and just need Postgres
Neon stays out of your way and speaks plain Postgres.
