Supabase vs Neon (2026): Which Postgres Should You Use?

Supabase and Neon both give you managed Postgres with a generous free tier, and both are hugely popular with developers building on Next.js, Remix, SvelteKit, and similar frameworks. They show up side by side in every "best free Postgres" discussion, and at first glance they look like direct competitors.

They're not quite. Supabase is a backend platform that happens to be built on Postgres. Neon started as Postgres reimagined for serverless, and has since added its own backend services around that database. Where each one started still shapes everything else: what you get, how the free tier behaves when your app is quiet, how pricing grows, and how much you build yourself.

We run MyKavo on Supabase, so I'll be clear about that bias, and equally clear about the situations where Neon is the better pick.

The short answer#

• Choose Supabase if you want a mature, all-in-one backend: a database plus authentication, file storage, auto-generated APIs, and realtime, built to work together, so you can build a full app without assembling separate services.
• Choose Neon if Postgres is what matters most to you and you value database branching, scale-to-zero pricing, or many small projects. Neon now offers auth, object storage, and functions too, but they're newer, and you can just as easily bring your own.

Now the details.

What each one actually is#

Supabase gives each project a dedicated Postgres database, surrounded by a set of services: Auth (sign-up, login, social providers, magic links), Storage (file uploads with access rules), an auto-generated REST and GraphQL API over your tables, Realtime (subscribe to database changes, broadcast, presence), Edge Functions, and a dashboard with a table editor and SQL editor. Security is handled through Postgres Row Level Security, tied directly to your auth users.

Neon separates Postgres storage from compute, so compute can scale up under load and down to zero when idle. Its standout feature is branching: you can create a full copy of your database, schema and data, almost instantly, the way you'd branch code in Git. It's Postgres first, accessed with a connection string or Neon's serverless driver, and designed to fit into whatever backend or ORM you already use, like Prisma, Drizzle, or plain SQL. Around the database, Neon now also offers Managed Better Auth for sign-up and login, S3-compatible object storage, Functions for server-side code, and a Data API that serves your tables over REST.

Free tiers compared#

From both pricing pages, checked this month:

Neon now gives each free project twice the database storage (1 GB vs 500 MB), and both bundle auth, file storage, and functions. The bigger differences are in how idleness works, how long each bundle has been around, and realtime, which only Supabase includes.

Pausing vs scale to zero: the difference that matters most#

This is where many people make their decision, so it's worth understanding precisely.

Supabase pauses idle free projects. If a free project doesn't get enough database activity over a week, it's paused. Your data is safe, but the project stops serving requests entirely until someone clicks Resume in the dashboard. Supabase sends warning emails, but if nobody acts, the app is down.

Neon scales compute to zero. On the free plan, compute shuts down after 5 minutes without queries, and it can't be kept on. But it wakes up automatically on the next query. The cost is a short delay on that first query, typically a few hundred milliseconds by Neon's own figures, rather than an outage.

For a demo, portfolio, or low-traffic app that people open occasionally, that's a meaningful difference. A Neon-backed app that nobody visits for a month still works when someone opens it, just a little slower on the first request. A Supabase free project in the same situation may be paused.

For apps with daily users, neither behavior matters much. Supabase projects with regular activity don't pause, and Neon compute stays warm under steady traffic. And on paid plans, Supabase projects never pause.

Compute and pricing as you grow#

Supabase paid plans start at $25 a month for Pro, which includes $10 of compute credits. You choose a compute size for each project, and pay for usage above included amounts, such as extra monthly active users, storage, and egress. The model is predictable: a steady monthly bill that grows in understandable steps.

Neon bills paid usage by compute time and storage. On the Launch plan, compute costs $0.106 per CU-hour and storage $0.35 per GB-month. Because compute scales to zero, you pay nothing for compute while the database is idle. For apps with spiky or low traffic, and for many small databases, that can be very cost-effective. For databases that are busy around the clock, always-on compute costs add up, and you'll want to compare with a fixed-size plan.

Also factor in what you'd pay elsewhere. Both now include auth and file storage alongside the database. If you need realtime on Neon, you'll add a separate service with its own free tier and pricing, while Supabase's plan includes it.

A simple way to think about it: Neon rewards idle time. Supabase rewards steady use, with a predictable monthly plan that covers its whole bundle.

Branching#

Neon's branching is its signature feature and genuinely useful. You can create a branch of your production database, with real schema and data, in seconds, and use it to:

• test a migration safely before running it on production,
• give every pull request its own database for preview deployments,
• reproduce a bug against realistic data without touching production.

Supabase also supports branching, tied to your Git workflow, so preview environments can get their own database with your migrations applied. It's more oriented around applying migrations and seed data to fresh branches than copying production data instantly. Both are useful. Neon's is simpler and more central to its product.

Auth, storage, and APIs#

This is still Supabase's biggest advantage, though the gap is narrower than it used to be.

With Supabase, a new project already has user sign-up and login, social providers, email templates, file storage with access rules, and an API over your tables, all respecting the same Row Level Security policies. These pieces have been part of Supabase for years and are built to work together. For a solo developer or small team, that's weeks of work you don't have to do.

Neon now offers its own versions: Managed Better Auth, which stores users and sessions in your Neon database (free up to 60,000 monthly active users), S3-compatible object storage (5 GB free per project), Functions for server-side code, and a Data API that serves your tables over REST. They're much newer than Supabase's equivalents, so check that they cover what you need. Many teams on Neon still bring their own pieces instead, like Auth.js or Clerk for auth, S3 or Cloudflare R2 for files, and their framework's server routes with an ORM for the API layer. That flexibility is real, but it's more to assemble, secure, and maintain.

Developer experience#

Both have good dashboards, CLIs, and documentation.

Supabase shines if you want to click around: a table editor, SQL editor, auth user management, storage browser, logs, and security and performance advisors that flag common mistakes, all in one dashboard. It also generates TypeScript types from your schema and has a local development setup that runs the whole stack on your machine.

Neon shines if you live in code: a clean connection-string workflow, a serverless driver designed for edge and serverless functions, fast branch creation from the CLI or API, and close integration with Vercel and other deployment platforms for preview databases.

Connection handling in serverless apps#

If you deploy to serverless functions, database connections matter. Each function instance can open its own connection, and traditional Postgres has a limited number available.

Both handle this. Neon offers built-in connection pooling and a serverless driver that works over HTTP and WebSockets, designed for edge runtimes. Supabase provides a connection pooler for serverless workloads, and its auto-generated API means many apps talk to the database over HTTP without managing connections at all.

Migrations and schema changes#

How you change your database over time matters as much as where it lives.

On Supabase, the CLI manages migrations as SQL files in your repository. You can create tables in the dashboard and pull the changes into migration files, or write migrations by hand and push them. Local development runs the full Supabase stack, so you can test migrations against auth and storage behavior too, not just the database.

On Neon, you'll typically manage migrations with your ORM or migration tool of choice, such as Prisma Migrate, Drizzle Kit, or plain SQL files. Branching makes testing easy: create a branch from production, run the migration on it, check that your app still works against the branch, then apply it to production.

Either way, the risky moment is the same: a migration that runs cleanly can still change what your app shows. A renamed column, a dropped default, or a changed data type can leave pages quietly empty or broken even though no error appears anywhere.

Three real-world scenarios#

A solo founder building a SaaS MVP. Needs sign-up, login, a dashboard, file uploads, and billing within a few weeks. Supabase is usually the faster path, because its auth, storage, and APIs are mature and already work together.

An agency building many small client sites with a database each. Wants dozens of small, mostly idle databases without paying for idle compute. Neon's generous project limit and scale-to-zero fit well.

A team with an existing Next.js app, Prisma, and Clerk for auth. Only needs a Postgres host that works well with serverless deploys and preview branches. Neon slots in naturally, though Supabase's database works fine here too.

Mistakes to avoid when choosing#

Choosing on free storage. Neon offers 1 GB per project and Supabase 500 MB. Either way, it's rarely the deciding factor.

Ignoring idle behavior. If your app will be quiet for days at a time on a free plan, Neon's automatic wake-up and Supabase's manual resume lead to very different user experiences.

Underestimating auth. "We'll add auth later" is one of the most common ways small projects stall. If you don't already have an auth plan, pick a platform whose built-in auth you trust. Supabase's is the more established of the two.

Forgetting backups. Neither free tier should be your only copy of important data. Set up your own backups either way.

Which one should you choose?#

Choose Supabase when:

• You want a mature, all-in-one backend with auth, storage, and APIs included.
• You're a solo developer or small team shipping a full app fast.
• You want Row Level Security tied directly to your users.
• You want realtime features.
• You prefer a predictable monthly plan.

Choose Neon when:

• Postgres is your priority and you already have (or want to choose) your own auth and storage, or you're happy with Neon's newer built-in options.
• You want many small databases, like one per client or per experiment.
• Branching for previews and safe migrations is central to your workflow.
• Your traffic is spiky or low, and you want to pay nothing for idle compute.
• You want a free-tier app that wakes itself up rather than pausing.

Can you use both? Some teams do: Supabase for a main app, Neon for side projects or per-customer databases. For most small teams, one is enough.

What neither one tells you#

Both platforms show you database health: connections, queries, storage, compute. Neither tells you what your live app looks like to users after a change.

That gap matters more than people expect. A migration that renames a column can leave a page quietly showing empty lists. A data update can blank out your pricing table. A paused free project or an exhausted compute budget can break sign-up. Your database dashboard shows healthy metrics throughout, because from the database's point of view, nothing is wrong.

Where MyKavo fits in#

MyKavo is our product, so here's exactly what it does. MyKavo watches the public pages of your app, like your homepage, pricing, sign-up and login pages, and key content pages, and alerts you when something important breaks or changes: error statuses, missing content, changed titles or meta tags, removed scripts, or missing forms and buttons. Every alert shows the before and after, ranked by severity.

It works with either database, because it only looks at what visitors see. For triggering checks at the right moment:

• With Supabase, a Database Webhook or pg_net trigger can start a MyKavo check whenever your data changes, for example when a post is published.
• With Neon (or Supabase), deploy checks can run after every deploy from GitHub Actions, Netlify, Vercel, or any CI with one curl command, including right after a migration ships.

Triggered checks are part of the Pro and Agency plans. The free plan monitors one site and five pages on a weekly scan. MyKavo never connects to your database, and it doesn't monitor query performance or storage. Use Supabase's or Neon's own dashboards for that.

The bottom line#

If you want a mature, whole backend in one place, choose Supabase. If you want excellent serverless Postgres with branching and scale-to-zero, and you're happy to use Neon's newer backend services or pick your own, choose Neon. Both are standard Postgres, so neither choice traps you.

Whichever you choose, the database dashboard only tells half the story. MyKavo watches your live app's pages and tells you, with evidence, when a data change, migration, or deploy breaks something your users can see. Start free.
