Neon vs Supabase: Which Postgres Platform Should You Use?

Neon is serverless Postgres with branching and scale-to-zero; Supabase is Postgres plus auth, storage, realtime and APIs. How they differ, free tier limits, pricing, cold starts and pausing, and which fits an AI-built app.

Neon and Supabase both give you a hosted PostgreSQL database in a couple of clicks, and both are popular with AI app builders. But they're different kinds of product.

  • Neon is a database: serverless Postgres with instant branching and scale-to-zero. Now part of Databricks.
  • Supabase is a backend: Postgres plus authentication, file storage, realtime updates, auto-generated APIs and edge functions. (What is Supabase?)

Pricing as of October 2026 from neon.com/pricing and supabase.com/pricing.

Side by side

Neon Supabase
What you get Postgres Postgres + auth + storage + realtime + APIs
Free plan 100 compute-hours and 1 GB per project; up to 100 projects 500 MB database; 2 active projects
Idle behaviour (free) Scales to zero after 5 minutes; wakes on the next query Paused after 1 week of inactivity; must be restored
Paid entry Usage-based (Launch) Pro, $25/month
Branching Instant copy-on-write branches Branching available, heavier
Auth built in No (use your own) Yes
File storage No Yes
Row-level security Postgres RLS (you write it) Central to how it works

Where Neon shines

  • Branching. Create a full copy of your database — data and all — in a second, for a preview deploy, a test, or letting an AI agent experiment safely. Delete it after. (Preview environments for every branch)
  • Scale to zero. Idle databases cost nothing in compute. Great for side projects and many small databases.
  • Generous free tier for many projects.
  • Just Postgres. Works with any framework, ORM or auth library.

Watch for: cold starts. A database that scaled to zero takes a moment to wake on the first query — usually well under a second, but noticeable on a rarely-visited app. Paid plans can disable scale-to-zero. Serverless environments may also need Neon's connection pooling. (Postgres connection pooling)

Where Supabase shines

  • Everything in one place. Login, file uploads and realtime without wiring up separate services. That's why Lovable and Bolt use it.
  • Instant APIs. Query your tables straight from the frontend, protected by row-level security. (Supabase RLS explained)
  • A friendly dashboard with a table editor and SQL editor.

Watch for:

  • Free projects pause after a week of inactivity — fine for experiments, a problem for a real app with occasional users.
  • RLS is the security model. If policies are missing or wrong, the frontend can read data it shouldn't. (new row violates row-level security)
  • More to move if you ever leave: auth, storage and APIs, not just the database.

Which should you choose?

  • You're using Lovable, Bolt or similar: Supabase — it's what they integrate with. (Supabase vs Firebase)
  • You want login and file storage handled for you: Supabase.
  • You have your own backend and just need Postgres: Neon.
  • You want a throwaway database copy per branch, or per AI agent task: Neon's branching is excellent.
  • Lots of small, mostly-idle projects: Neon's free tier.

Or: Postgres next to your app

Both are managed services billed by usage. A third option is running Postgres on the same server as your app — no cold starts, no pausing, no per-query metering, at the cost of handling backups yourself (or having your platform do it). (VPS vs PaaS, Which database should an AI-built app use?)

EasySpawn runs PostgreSQL on your own server alongside your app — always on, never paused, with daily backups and a flat monthly price. See how it works or join the waitlist.
