The right app backend depends on who will maintain it, whether you want hosted or self-hosted, and what the app needs to remember. Check the database type, bundled features, data export and free limits. This page lists ten options in no particular order, then covers how to choose and move.
If you're building an app, or asking an AI app builder to make one for you, Supabase is a name you'll probably meet. It gives your app a place to keep its data, handle sign-ins and store files, so you don't have to build all that from scratch. It's popular, but it isn't the only option, and some founders want something simpler, more open, or closer to a tool they already know.
Here are ten Supabase alternatives in no particular order, sorted alphabetically. They're backends and hosted databases, which is the hidden machinery behind an app. I've mixed smaller and open-source tools with a couple of big names, and every description comes from each tool's own website and directory listings. You don't need to be a developer to follow this. My piece on why your business should care about its database explains why the choice matters.
App backend options at a glance
In the free plan column, Yes means the tool's own site says there's a free plan or that the software is free to run yourself. Trial only means there's a free trial but no ongoing free plan. Free plans often have limits on projects, storage or activity, so read the current terms before you build on one.
| Tool | Type | Good for | Free plan |
|---|---|---|---|
| Appwrite | Open-source app backend | Logins, data, files and functions in one | Yes |
| Back4App | Hosted app backend | Launching a backend without managing servers | Yes |
| Convex | Reactive backend platform | Apps where data updates live on screen | Yes |
| Directus | Backend and content platform | Putting an admin panel over existing data | Yes |
| Firebase | Google app platform | Mobile and web apps with many built-in services | Yes |
| Neon | Hosted Postgres | A Postgres database that scales down when idle | Yes |
| Nhost | Hosted backend | A Postgres backend with a GraphQL interface | Yes |
| PocketBase | Single-file open-source backend | Small apps and prototypes you host yourself | Yes |
| Turso | SQLite-based database | Lightweight databases, one for each customer | Yes |
| Xata | Hosted Postgres | Testing changes safely on a copy of your data | Trial only |
Ten app backend and hosted database tools to consider
Appwrite
Best for: Founders who want one open-source backend covering sign-ins, data, file storage and background functions for an app.
Back4App
Best for: Teams who want a ready-made hosted backend with a database, sign-ins and APIs and no servers to look after.
Convex
Best for: Builders making apps where changes should appear instantly for every user, such as shared boards or chat.
Directus
Best for: Businesses with an existing database who want a friendly admin screen and ready-made APIs over the top.
Firebase
Best for: Founders building mobile or web apps who want sign-in, data, hosting and notifications from one big provider.
Neon
Best for: Teams who just want a modern Postgres database in the cloud, with extras like sign-in and storage available.
Nhost
Best for: Builders who like Postgres and GraphQL and want sign-in, storage and functions bundled in a managed service.
PocketBase
Best for: Solo builders making small apps who like the idea of a whole backend packed into one simple file.
Turso
Best for: Developers who prefer SQLite's simplicity and want a hosted version, including one small database per customer.
Xata
Best for: Teams who want to try database changes on safe copies of their data before touching the live version.

What an app backend does, in plain English
Think of an app as a shop. The screens people see are the shopfront. The backend is the stockroom and the till: it remembers who's logged in, stores the information, keeps uploaded files and runs jobs behind the scenes.
- A database stores everything your app needs to remember, such as customers, bookings or posts.
- Authentication handles sign-ups, logins and password resets.
- File storage keeps images, documents and other uploads.
- Functions run small bits of code on the server, such as sending a confirmation email.
- Realtime features push changes to every user's screen without a refresh.
How to choose an app backend or database
- Match your skills. A tool that suits an experienced developer can overwhelm a first-time founder. Be honest about who'll maintain it.
- Hosted or self-hosted. Hosted tools are run for you. Self-hosting gives more control but means you own updates and security.
- Database type. Some tools use Postgres, a widely used database, others use SQLite or their own style. Popular, standard databases are easier to move away from later.
- What's bundled. Decide whether you need sign-ins, storage and functions from the same provider or just a database.
- Fit with your builder. If an AI app builder or code editor is doing the work, check which backends it supports. My comparison of AI coding editors shows how many tools now do this.
- Free limits. Look at what pauses, sleeps or stops when you reach a limit on a free plan.
Questions to ask before you commit your app's data
- Who owns the account that holds our data, and is it in our business name?
- Can we export everything, in a standard format, if we want to leave?
- Where is the data stored, and does that matter for our customers' privacy rules?
- What happens to a free project that goes quiet for a while?
- Who'll apply updates and fix problems if something breaks at night?
Data protection rules differ by country and by the kind of information you hold, so check the official guidance for your situation or speak to a professional adviser before storing customer details.
Moving an app backend: what to know
- Your data is the heavy part. Ask your developer to take a complete export before anything changes.
- Sign-in details can be the trickiest piece, because people's accounts need to carry across smoothly.
- Test the new setup with a copy of your app before real customers touch it.
- Plan the move for a quiet time, and keep the old backend running until you're sure.
- If it's a bigger job, my notes on database migration help explain what that kind of support involves.
App backend mistakes to avoid
- Building on a free project and forgetting it may pause when it's quiet.
- Letting a freelancer hold the only login to your app's data.
- Choosing a tool because it's trending, not because it fits what your app needs.
- Skipping backups and assuming the provider takes care of everything.
- Collecting more customer information than the app needs.
Why a smaller backend tool can be worth a look
Smaller and open-source backends are often simpler, more focused and easier to understand than the biggest platforms. Some can even run on a modest server you control. That can suit a prototype, an internal tool or a side project very well.
Before relying on one, check how actively it's updated, how your data can be exported, how big its community is, and what the company behind it says on its own website. If your developer likes it, that counts for a lot.
Do you make a backend, database or app-building tool? Tool makers can ask to be considered for a featured place on this list.
Choosing a backend for your app
Write down what your app has to remember, who has to log in and what has to update live. Shortlist two tools that cover that list, try each with a small test project, and choose the one you or your developer find easiest to live with. Keep the account in your business's name and keep an export somewhere safe.
Frequently asked questions
What is a backend as a service?
It's a ready-made set of behind-the-scenes features for an app, usually a database, sign-in, file storage and functions, run by a provider so you don't have to build them from scratch.
Do I need a developer to use these tools?
Most of them are designed with developers in mind, though some are friendlier than others. If you're using an AI app builder, it may set the backend up for you, but you should still know who owns the account.
Are open-source backends safe for a business app?
They can be, but safety depends on how well they're maintained and set up. Check how actively the project is updated, and make sure someone is responsible for security if you host it yourself.
Can I move my app's data to a different backend later?
Usually, yes, especially if the tool uses a standard database. Always check what export options exist before you build, and test a move with a copy.
Is a free plan enough to launch an app?
Sometimes for a prototype or a small launch. Limits vary, so check what pauses or stops at the free level and be ready to move up if you grow.
