9 Best Supabase Alternatives in 2026 (and When to Switch)

We use Supabase for MyKavo, and I'd recommend it to most people building a web app today. So it might seem odd for us to write a post about alternatives. But the honest truth is that no backend is the right fit for every project, and people look for Supabase alternatives for good reasons: they need offline-first mobile sync, they want to self-host with less complexity, they only need a database and not a whole platform, or they're running into the free tier's pausing and want something that behaves differently.

This guide covers nine real alternatives, grouped by what you'd actually replace Supabase with. For each one, I'll say what it's good at, what the catch is, and the specific reason you'd choose it over Supabase. If none of those reasons apply to you, staying on Supabase is usually the right call.

First: why are you looking?#

The right alternative depends almost entirely on why you want to leave. The most common reasons:

• Pausing on the free tier. Free projects pause after a week of inactivity. If that's your only problem, the cheapest fix may be Supabase Pro or a different free database, not a different platform.
• You only need a database. If you're not using Supabase Auth, Storage, or Realtime, a pure Postgres host may be simpler.
• Mobile, offline-first apps. Supabase doesn't have built-in offline sync like Firebase's Firestore.
• Self-hosting. Supabase can be self-hosted, but it's a collection of services. Some alternatives are much simpler to run yourself.
• Different data model. You want documents instead of tables, or SQLite instead of Postgres.
• Cost at scale. Your usage pattern fits a different pricing model better.

Keep your reason in mind as you read.

Full backend platforms (replace everything)#

These replace Supabase's whole bundle: database, auth, storage, and functions.

1. Firebase#

Google's app platform, built around Cloud Firestore, a NoSQL document database, plus Authentication, Hosting, Cloud Functions, Cloud Messaging for push notifications, Crashlytics, and Analytics.

Choose it over Supabase if: you're building a mobile-first app that needs offline support and automatic sync, you want push notifications and crash reporting in the same platform, or your data is simple and document-shaped.

The catch: Firestore's default Standard edition has no joins (the newer Enterprise edition adds join-style queries), so relational data gets duplicated and harder to query. Pricing on the Blaze plan is per document operation, which is cheap at small scale but can grow unpredictably. Cloud Functions and Cloud Storage aren't available on the free Spark plan. And it's proprietary, so leaving is harder than leaving Supabase. We compare them in depth in our Supabase vs Firebase guide.

2. Appwrite#

An open-source backend platform with a database, authentication, storage, functions, and messaging. It offers a hosted cloud version and is designed to be straightforward to self-host with Docker.

Choose it over Supabase if: you want an open-source, self-hostable backend with tables, rows, and relationships behind a unified API, and you prefer not to work in SQL.

The catch: its default database isn't Postgres and is used through Appwrite's API rather than SQL. A managed PostgreSQL option exists, but only on paid plans. The ecosystem and community are smaller than Supabase's.

3. PocketBase#

An open-source backend in a single executable file: a SQLite database, authentication, file storage, realtime subscriptions, and an admin dashboard, all in one program you can run on almost any small server.

Choose it over Supabase if: you want the simplest possible self-hosted backend for a small app, internal tool, or prototype, and you're comfortable managing one small server.

The catch: it runs as a single instance with SQLite, which suits small and medium apps but isn't designed for large-scale, high-write workloads. You're responsible for hosting, updates, and backups.

4. Nhost#

An open-source backend built on Postgres with a GraphQL API (via Hasura), plus authentication, storage, and functions.

Choose it over Supabase if: your team prefers GraphQL as the main API and you want a Postgres foundation similar to Supabase's.

The catch: a smaller ecosystem than Supabase, and it's most compelling if you specifically want GraphQL.

5. Convex#

A backend platform built around a reactive database, where queries and server functions are written in TypeScript and the UI updates automatically when data changes.

Choose it over Supabase if: you're building a highly interactive, realtime TypeScript app and want queries, mutations, and server logic in one typed codebase without writing SQL.

The catch: it's a different model from a traditional SQL database, and you're committing to its way of working.

Database-first alternatives (replace mainly the database)#

If you mainly use Supabase as a Postgres host, these may fit better.

6. Neon#

Serverless Postgres with instant database branching and compute that scales to zero. The free plan includes 1 GB of storage per project, 100 compute-hours per project each month, and up to 100 projects.

Choose it over Supabase if: Postgres is what you mainly need, you want many small projects, or you'll use branching for preview environments and testing migrations.

The catch: Neon now offers auth, object storage, functions, and a REST Data API, but they're much newer than Supabase's equivalents, and there's no realtime service. Compute scales to zero after 5 minutes idle on the free plan, so the first query after a quiet period is a little slower. See our Supabase vs Neon comparison for details.

7. Turso#

Hosted SQLite (via libSQL), designed for many small databases close to your users. The free plan includes up to 100 databases, 5 GB of storage, 500 million rows read, and 10 million rows written per month. Paid plans start at $5.99 a month, or $4.99 a month billed yearly.

Choose it over Supabase if: you're building a multi-tenant app with a database per customer, or you prefer SQLite's simplicity.

The catch: SQLite has fewer advanced features than Postgres, and you'll handle auth and storage elsewhere.

8. Cloudflare D1#

Serverless SQLite built for Cloudflare Workers. The free plan includes 5 GB of storage, 5 million rows read, and 100,000 rows written per day.

Choose it over Supabase if: your app already runs on Cloudflare Workers and you want your database on the same platform.

The catch: it's most natural inside the Cloudflare ecosystem, and daily write limits on the free plan need watching.

9. MongoDB Atlas#

Managed MongoDB, the most widely used document database. The free M0 cluster includes 512 MB of storage on shared infrastructure.

Choose it over Supabase if: your data is document-shaped and your team already knows MongoDB.

The catch: the free tier is small and has no backups, and document databases make relational queries harder.

Also worth knowing: PlanetScale, once a popular free option, no longer has a free plan. Its cheapest option is single-node Postgres from $5 a month.

One more option: self-hosting Supabase itself#

Before you switch platforms, it's worth knowing that Supabase is open source and can run on your own infrastructure. If your reason for leaving is the hosted platform, such as data residency requirements, wanting everything on your own servers, or avoiding usage-based pricing, self-hosting Supabase keeps your code, schema, and client libraries exactly as they are.

The trade-off is operational. Self-hosted Supabase is made up of several services working together (Postgres, the auth server, the REST API layer, realtime, storage, and the dashboard), usually run with Docker. You become responsible for updates, backups, security patches, scaling, and uptime. For a team with infrastructure experience, that's manageable. For a solo founder, it often costs more in time than the hosted plan costs in money.

A simpler middle ground for many teams: stay on hosted Supabase, upgrade the projects that matter to Pro, and keep regular off-site backups with the CLI so you're never fully dependent on any single provider.

What to look for in any alternative#

Whichever option you're considering, check these five things before committing:

1. The free tier's catch. Every free tier has one: pausing, scale-to-zero, daily limits, expiry, or missing backups. Find it before you build on it.

2. How pricing grows. Plan-based, usage-based, and per-operation pricing behave very differently at scale. Estimate your costs at ten times your current usage, not just today's.

3. Auth migration. If you have real users, moving them without forcing password resets is often the hardest part of any backend switch. Check whether the new platform can import password hashes from Supabase Auth.

4. How hard it is to leave again. Standard Postgres and SQLite are portable. Proprietary data models and rules languages lock you in more tightly. You may not plan to move twice, but it's worth knowing the cost.

5. The ecosystem. Documentation quality, community size, client libraries for your framework, and how quickly issues get answered matter more than a feature list when something breaks at midnight.

Quick comparison#

Should you actually switch?#

Before migrating, check whether a smaller change solves your real problem:

• If pausing is the issue, Supabase Pro ($25 a month) removes it, and adds backups. That's almost always cheaper than the engineering time of a migration.
• If egress or database size is the issue, better queries (select only needed columns, paginate, cache images) often solve it.
• If you only need Postgres, you can keep Supabase and ignore the other features, or move just the database to Neon.
• If you need offline mobile sync, that's a genuine reason to consider Firebase.

It also helps to be honest about the cost. Even a small app's migration usually means rewriting data access code, moving auth users, re-creating storage buckets and permissions, updating environment variables across environments, and retesting every flow. For a solo developer, that's easily a few weeks of work that isn't going into the product.

Migrations are expensive and risky. The best reason to switch is a fundamental mismatch, not a limit you can pay or optimize your way past.

How to migrate without breaking your live app#

If you do decide to switch, the biggest risk isn't the data transfer itself. It's the live app behaving differently afterward in ways nobody catches for days.

1. Take a full backup first. Use the Supabase CLI's db dump for your schema and data, and export Storage files and auth users separately.

2. Record how your live app looks and behaves now. Before you touch anything, capture your key pages: homepage, pricing, sign-up, login, dashboard entry points, and your most visited content. Note what each shows, including titles, meta tags, key content, and whether forms and buttons are present.

3. Migrate in stages. Run the new backend alongside the old one if you can, and move one feature at a time rather than everything at once.

4. Test auth thoroughly. Password hashes, social logins, email templates, and redirect URLs are where migrations most often go wrong. Test sign-up, login, password reset, and email confirmation with real accounts.

5. Compare the live app after each stage. Check every key page against your "before" record. Look for missing content, empty lists, broken forms, and changed titles or meta tags, which can also hurt search rankings.

6. Keep the old backend available briefly. Don't delete it until you're confident everything works.

7. Watch search and traffic for a few weeks. If your app has public, indexed pages, compare Search Console clicks and impressions for the weeks after the migration with the weeks before. A drop on specific pages usually points to content or tags that changed during the move.

Where MyKavo fits in#

MyKavo is our product. It's useful here for steps 2 and 5: it records your key pages as an approved baseline, including screenshots, titles, meta tags, content, scripts, and the forms and buttons you mark as important, and then flags the meaningful differences on later scans with the before and after side by side, ranked by severity. During a migration, that turns "does everything still work?" from a manual checklist into a list of exact changes. Deploy checks on Pro and Agency plans can run a comparison automatically after every deploy.

If you stay on Supabase, a Supabase Database Webhook or pg_net trigger can call your site's MyKavo deploy hook and start a check whenever your data changes (deploy checks are on the Pro and Agency plans). It never touches your database, only the webhook call.

What it won't do: MyKavo doesn't move data, test your API directly, or check logins behind authentication. It watches what your public pages show.

The bottom line#

Supabase is the right choice for most web apps, and it's what we use. But Firebase is better for offline-first mobile apps, PocketBase and Appwrite are simpler to self-host, and Neon, Turso, or D1 can be better when you only need a database. Pick based on the specific reason you're looking, and if that reason is pausing or backups, try Supabase Pro before planning a migration.

Whatever you run, and especially if you're migrating, make sure you know what changed on your live app. MyKavo records your key pages and shows you, with evidence, exactly what's different on every scan. Start free.
