Supabase vs Neon
Both give you Postgres. One wraps it in a platform; the other is the database first, with platform pieces arriving as beta add-ons.
The verdict
Choose Supabase when you want auth, storage, realtime and row-level security built around Postgres; choose Neon when you want the database first, with branching, and plan to write your own backend on top of it.
Both run standard Postgres, so the data layer itself is not the decision. The decision is how much you want built for you above it.
Neon does one thing extremely well: a Postgres instance that branches like a git repository and scales storage and compute separately. Supabase does more, because it is not only a database.
Side by side
Neon's rows are shorter because it started as the database alone; its auth, storage and Data API are newer and still in beta. That is the whole comparison in one table.
| Dimension | Supabase | Neon |
|---|---|---|
| What it is | A backend platform built on Postgres | Serverless Postgres first; auth, object storage and a Data API added as beta products |
| Auth | Built in, with row-level security in the database | Neon Auth (managed Better Auth), in beta; or bring your own |
| Storage for files | Built in, with access policies | Neon Object Storage (S3-compatible), in beta; partner integrations documented |
| Realtime subscriptions | Built in, on top of Postgres replication | Not included |
| Database branching | Available on paid plans | The core feature. Instant, copy-on-write branches |
| Compute model | Provisioned Postgres, sized to a plan | Scales to zero and back up per branch |
| Client SDK | Yes, generated from your schema | Any Postgres driver by default; a PostgREST-style Data API with JWT auth and RLS is documented |
| Self-hosting | Supported, open source | Not offered |
| Where it fits | Front end talks to the database directly, with RLS as the guard | Usually behind a backend you already have or are writing; the Data API allows the direct-from-front-end shape too |
Supabase
Where it wins
- Auth, storage and realtime ship on day one, so a small team skips building three services.
- Row-level security enforces access in the database, not in application code that can drift.
- A generated client SDK means a front end can query Postgres directly under RLS.
- Self-hosting is real, so a pricing change is not a forced migration.
Where it hurts
- Branching arrived later than Neon's and is not the product's core strength.
- You inherit platform defaults (connection pooling, auth flows) even when you only wanted the database.
- Running your own backend anyway means paying for platform features you route around.
Neon
Where it wins
- Branching is instant and cheap, so a preview environment per pull request is normal, not a luxury.
- Scale-to-zero compute means a low-traffic branch costs almost nothing while idle.
- Few platform opinions. Auth and storage are optional add-ons, and you choose your own backend framework.
- Standard Postgres underneath, so any ORM or migration tool works unmodified.
Where it hurts
- Auth and object storage are newer, beta products; realtime you build yourself or bring in a separate service.
- Row-level security is available because it is Postgres; the Data API that exposes it to a front end is newer than Supabase's and its client library is still being published.
- No self-hosting option, so leaving means a database dump and a new home for it.
Pick by what you want to write yourself
These two are not really the same category, which is why the comparison confuses people. Neon competes with a managed Postgres box. Supabase competes with a backend.
- 01Choose Supabase if you want auth, file storage and row-level security ready before you write a feature.
- 02Choose Neon if you already have a backend, or are writing one, and want branching without a platform on top.
- 03Choose Neon if preview databases per pull request matter more than anything else on this page.
- 04Choose neither yet if you have not decided whether the front end talks to the database directly or through your own API. That answer decides more than this table does.
What we would pick, and why
New product, small team, no backend yet
Your situation
You need auth, storage and a database working together fast.
What we would build on
Supabase. Building those three separately costs weeks you do not have.
Existing backend, adding Postgres
Your situation
A Node, Python or Go service already owns your API layer.
What we would build on
Neon. You do not need a platform's auth system fighting the one you have.
Heavy CI, many preview environments
Your situation
Every pull request should get its own database state.
What we would build on
Neon. Instant branching is built for exactly this.
Regulated client, self-hosting matters
Your situation
A security review will ask where the whole stack runs, not just the database.
What we would build on
Supabase, self-hosted. Neon has no self-hosted option to point at.
Where we run each one
We run Supabase in four production systems, plus the company's own CRM. Shift Link handles workforce compliance for healthcare and logistics. Lexpair matches legal leads. Trading Copilot sends real-time forex alerts, and Extraaje runs employee engagement.
Every one of those needed auth and row-level security from day one, which is Supabase's strongest case. When a client already runs its own backend and only needs the database, we reach for Neon's branching model instead.
Common questions
01Can you put Neon behind Supabase, or vice versa?+
Not directly. They are two different products wrapping the same underlying technology, not layers you stack. Some teams use Neon for CI branch databases while running Supabase in production, but that is two separate databases, not one combined stack.
02Is Neon's Postgres the same as Supabase's?+
Both run standard, unmodified Postgres, so extensions, migrations and query behaviour are the same. The difference is entirely in what sits around the database, not in the database engine itself.
03Which is easier to migrate away from?+
Both give you a Postgres dump, which any Postgres host can restore. Supabase adds more to unwind first: row-level security policies, auth users and storage objects that a plain dump does not carry. Neon's export is closer to just the data.
04Do we need Supabase's extra features if we already have a backend?+
Usually not, and that is the case for Neon. Paying for auth and storage you route around is waste. If your backend already owns those concerns, a database that lets you use only the database is the better fit.
