Pick Neon when you want plain Postgres that scales to zero, cheap preview branches for every pull request, and many small databases (one per client, tenant, or agent). Pick Supabase when you want a full backend in one dashboard: auth, storage, realtime, and an auto-generated API, with a predictable flat monthly bill. If you use Drizzle or Prisma from Next.js server code and bring your own auth, both work well, and the deciding factor is mostly how your traffic and billing look.
That was a simple split a year ago. In 2026 the two products moved toward each other, so the old comparison posts need an update.
What changed in 2026
Neon is now a backend platform too. After the Databricks acquisition, Neon's pricing page lists Lakebase Postgres plus Managed Better Auth, a Data API over HTTP, Functions, Object Storage, an AI Gateway, and Realtime in beta. Prices also dropped: compute is $0.106 per CU-hour on Launch and $0.222 on Scale, storage is $0.35 per GB-month, and paid plans have no monthly minimum. The Free plan now gives up to 100 projects, each with 100 CU-hours and 1 GB of storage per month.
Supabase tightened its defaults. New tables in the public schema are no longer exposed to the Data API automatically. That became the default for new projects on May 30, 2026 and reached all existing projects on October 30, 2026. Supabase also announced usage-based pricing for logs on September 25, with a grace period for existing organizations through early 2027, and new free projects on the default email sender can no longer edit auth email templates.
If you read a Neon vs Supabase post from 2025, its pricing numbers and feature lists are now wrong.
The short comparison
Here is how the two compare on the points that usually decide it:
- Billing: Neon is usage-based and scales to zero. Supabase charges a plan fee plus compute per project.
- Free plan: Neon gives 100 projects with 100 CU-hours and 1 GB each. Supabase gives 2 active projects with a 500 MB database, paused after a week without activity.
- Paid entry: Neon has no minimum and bills about $0.106 per CU-hour on Launch. Supabase Pro starts at $25 per month with a $10 compute credit.
- Auth: Neon offers Managed Better Auth. Supabase Auth includes 50,000 monthly active users on the free plan.
- Best fit: Neon suits spiky traffic, many small databases, and preview environments. Supabase suits a full backend for one product, especially with realtime.
Where Neon wins
Idle databases cost nothing for compute. Most client projects I work on sit idle at night and on weekends. On Neon, compute scales down to zero after about five minutes of inactivity, and you pay storage only. For a portfolio of small sites or a staging environment, that difference adds up.
Branches make preview deployments honest. A Neon branch is a copy-on-write clone of your database, created almost instantly. Pair it with Vercel preview deployments and every pull request gets its own data, so a migration that breaks production breaks a throwaway branch first.
Database-per-tenant is affordable. Neon has no per-project fee, so one database per customer only costs what each customer actually runs. On Supabase, every extra project adds its own compute instance to the bill.
The catch is cold starts. A database that scaled to zero needs a moment to wake up, so the first request after a quiet period is slower. On Launch you can turn scale to zero off for the production branch and keep it for everything else.
Where Supabase wins
One dashboard for the whole backend. Auth, file storage with a CDN, realtime subscriptions, edge functions, and a generated REST API come with every project. For a startup that wants to ship an MVP without assembling five services, that is still the fastest path.
Predictable bills. A Pro organization with one project on Micro compute costs $25 per month before overages. Finance teams like a number they can put in a spreadsheet, and Supabase paid projects never pause for inactivity.
Mature realtime and auth. Supabase Auth and Realtime have years of production use. Neon's Realtime is still in beta, and Managed Better Auth is new. If live updates are a core feature, Supabase is the safer bet today.
Connecting from Next.js 16 without surprises
Serverless functions open many short connections, so use the pooled connection string on both platforms.
On Neon, the pooled host has -pooler in its name. From Server Components and Route Handlers, the @neondatabase/serverless driver works over HTTP, which suits short-lived functions:
1import { neon } from '@neondatabase/serverless'2import { drizzle } from 'drizzle-orm/neon-http'34const sql = neon(process.env.DATABASE_URL!)5export const db = drizzle(sql)
On Supabase, use the Supavisor pooler in transaction mode (port 6543) for serverless code. Transaction mode does not support prepared statements, so turn them off in your driver:
1import postgres from 'postgres'2import { drizzle } from 'drizzle-orm/postgres-js'34const client = postgres(process.env.DATABASE_URL!, { prepare: false })5export const db = drizzle(client)
Keep a separate direct connection string for migrations, because schema changes should not run through a transaction pooler. If you are still choosing an ORM, I compared the two main options in Drizzle vs Prisma for Next.js App Router with Postgres.
The Supabase grants change, if you use supabase-js
If your app talks to Supabase only through an ORM on the server, the October 30 change does not affect you. If you call tables from the browser with supabase-js, any new table now needs an explicit grant before the API can see it:
1grant select on public.projects to anon;2grant select, insert, update, delete on public.projects to authenticated;
Row Level Security still decides which rows each role sees. The grant only decides whether the role can reach the table at all. Put both in your migrations so a code review shows exactly what is public. The details are in the Supabase changelog.
How I choose for a client project
I ask three questions before I create anything:
- Does the app need realtime or file uploads on day one? If yes, Supabase saves a week of wiring.
- Is traffic spiky or mostly idle? If yes, Neon's scale to zero usually costs less.
- Will there be many databases? Per-tenant or per-preview databases point to Neon.
When the answers are mixed, I pick based on the auth plan. A team already using Better Auth fits Neon well; I covered that choice in Better Auth vs Auth.js for Next.js 16. A team that wants hosted auth with row-level policies fits Supabase.
Either way, keep your schema in migrations and your queries in an ORM or plain SQL, not in dashboard clicks. Then moving from one host to the other is a pg_dump and a connection string change, not a rewrite. Slow pages usually come from query shape, not the host, which I wrote about in Postgres performance in Next.js.
Prices and limits here are from the Neon pricing page and the Supabase pricing page as of November 2026. Check both before you commit, because both companies changed them more than once this year.
