Supabase vs PocketBase: Which Database for Your First App?

Building your first app comes with plenty of decisions. What should the interface look like? Which features should you launch first? And where will all your app's data actually live?

That last question matters more than you might think. Your backend handles things like user accounts, saved information, permissions, and the logic that makes your app work beyond what people see on the screen.

Two options worth considering are Supabase and PocketBase. Both give you the tools to build a functional backend, but they approach the job differently.

Supabase is generally a better fit for apps that need relational data, managed infrastructure, and room to grow. PocketBase makes sense when you want a lightweight backend that's simple to run and host yourself. Your choice comes down to the app you're building, the work you're willing to manage, and where you expect the product to go.

Let's look at how Supabase vs PocketBase compares in practice.

Supabase vs PocketBase at a Glance

At first, these two platforms might seem interchangeable. They both offer authentication, APIs, database functionality, and other features you need to get an app running. The differences become clearer when you look at how they're built and what you need to manage yourself.

For the full technical details, see the Supabase documentation and PocketBase documentation.

The simplest way to understand the difference is this: Supabase gives you a broader backend platform built around PostgreSQL, while PocketBase bundles essential backend features into a compact application.

What Is Supabase?

Supabase is a backend platform built around PostgreSQL, a relational database used by everything from small web apps to large software systems.

Instead of setting up a database, authentication service, file storage, and API layer separately, you can get these capabilities through one platform.

Here's what that looks like in practice:

• Database: Store information in tables and connect related records.

• Authentication: Let users sign in with email and passwords, social login, and other supported methods.

• APIs: Access database records through generated APIs and client libraries.

• File storage: Handle user uploads, images, and documents with configurable access controls.

• Real-time features: Keep connected interfaces updated when relevant events occur.

• Backend logic: Use Edge Functions or PostgreSQL functions to handle operations that shouldn't run in the browser.

Imagine you're building a project management app. You'll probably need users, teams, projects, tasks, and comments. These records are connected, and you'll want to control who can see or change each one.

PostgreSQL is well suited to this kind of structure. You can define relationships between records, enforce constraints, and write queries to retrieve exactly the information your app needs.

Supabase also offers managed cloud hosting. You can get started without maintaining your own database server, which is useful when you'd rather spend your time building the product.

Where Supabase shines

Supabase is particularly useful when your app has several connected features, or you expect its data model to become more involved.

Its main advantages include:

• PostgreSQL supports relational data and complex queries.

• Managed hosting reduces day-to-day infrastructure work.

• Authentication, storage, and real-time features are available in one platform.

• Row-Level Security (RLS) lets you define which records users can access.

• You have several options for adding backend logic as your requirements change.

There are trade-offs, of course. You'll need to understand database relationships and permissions, even if an AI tool helps you configure them. Incorrect security policies can expose private data, and costs may increase as usage grows.

Self-hosting Supabase also involves considerably more setup than using its managed service.

What Is PocketBase?

PocketBase takes a more compact approach. It's an open-source backend that runs as a single application and includes an embedded SQLite database, authentication, file management, real-time subscriptions, an admin dashboard, and a REST-style API.

The appeal is straightforward: you get several essential backend features without having to assemble a large stack of separate services.

Say you're building a booking app for a local business. You need customer accounts, appointment records, available time slots, and perhaps a way for customers to upload reference images. PocketBase can handle the core backend needs of a project like this without requiring a separate managed database service.

Its admin dashboard is another useful feature. You can inspect collections and records while developing, which makes it easier to understand what's happening behind the scenes.

Where PocketBase shines

PocketBase works well for projects where simplicity and control over your own deployment matter more than having a large managed platform.

Its advantages include:

• A compact setup with a relatively small operational footprint.

• Built-in authentication, APIs, file management, and real-time subscriptions.

• SQLite, which is capable of handling many small-app workloads.

• Control over your own hosting environment.

• No recurring software subscription for PocketBase itself.

The catch is that you're responsible for the infrastructure. You'll need to handle hosting, backups, monitoring, updates, and recovery.

SQLite also has different concurrency characteristics from PostgreSQL, which matters if your app has heavy simultaneous writes or increasingly complex data requirements.

There's one more consideration: PocketBase's official documentation warns that full backward compatibility isn't guaranteed before version 1.0 and advises caution with production-critical applications. That doesn't make PocketBase unsuitable for every production project, but you should understand its upgrade and migration requirements before relying on it for critical business operations.

You can review the current guidance in the official PocketBase documentation.

Supabase vs PocketBase: 7 Key Differences

1. Database: PostgreSQL vs SQLite

This is the biggest difference between the two.

Supabase uses PostgreSQL, a relational database that lets you connect tables, enforce data constraints, run complex queries, and manage transactions.

PocketBase uses SQLite, an embedded database stored alongside the application. Its developer experience is organized around collections and records rather than working directly with a PostgreSQL database.

Neither option is automatically the right choice for every app.

If you're building a simple tool with a straightforward data model, PocketBase may provide everything you need. SQLite is a capable database, not just a temporary option for prototypes.

But if your app depends on relationships between users, organizations, subscriptions, projects, and transactions, PostgreSQL gives you a flexible foundation for managing that complexity.

Think about how your data connects today and how those relationships might change as you add features. That will tell you more than choosing a database based on popularity alone.

2. Setup and ease of use

PocketBase is relatively straightforward to run. Its compact deployment and built-in dashboard make it appealing if you're comfortable hosting your own backend.

Supabase offers a different kind of convenience. With its hosted service, you can create a project and start working with a database, authentication, and storage without first setting up a server.

For someone building an app without much coding experience, the difference isn't always obvious.

A backend might be easy to install but difficult to maintain. Another might require a little more configuration initially but take less effort to operate over time.

If you're using an AI app builder, consider how easily you can connect your chosen backend, configure the database, test authentication, and fix problems when something doesn't work as expected.

The goal isn't simply to get the backend running. It's to have an application you can keep developing without getting stuck every time you add a feature.

3. Authentication and security

Both platforms include authentication, so you don't have to build every part of a sign-in system yourself.

But signing in is only half the job. You also need to control what each user can access.

Imagine two customers using the same project management app. Each has an account, but neither should be able to open the other's private projects just by changing an ID in a URL.

Supabase uses PostgreSQL Row Level Security (RLS) to define which records a user can read or modify. This is particularly useful for SaaS applications with separate teams, workspaces, and customer data.

PocketBase offers collection-level API rules that control access to records and operations.

Both approaches can work well when configured correctly. Neither automatically guarantees that your application is secure.

Test your permissions with different accounts. Try accessing records that belong to other users, and check that sensitive operations can't be performed by someone who shouldn't have access.

Also, never put privileged server credentials in browser-side code. Authentication, authorization, and secure handling of secrets need to work together.

4. APIs and custom backend logic

Your app will probably need to do more than save information to a database.

Consider an ordering app. When a customer places an order, you might need to validate stock, calculate the final price, process payment, and send a confirmation email.

Some of these operations involve sensitive information and shouldn't run in the browser.

Supabase generates APIs around your database and supports additional backend logic through Edge Functions and PostgreSQL functions.

PocketBase provides a built-in REST-style API, with JavaScript hooks and Go extensions for customization.

Both can support real applications, but the implementation differs. Supabase offers a broader set of managed services, while PocketBase keeps the core setup more compact.

Before choosing, write down the actions your app needs to perform. Where will payments be processed? How will notifications be sent? Which operations need server-side validation?

Those answers will help you decide whether either backend fits without unnecessary workarounds.

5. Real-time features and file storage

Both platforms support real-time functionality and file uploads, but the details depend on what you're building.

Supabase offers real-time features for database changes, broadcasts, and presence, along with integrated storage and access policies.

PocketBase provides real-time subscriptions and built-in file management.

For a collaborative dashboard, users might need to see changes as teammates update records. For a booking app, you might want availability to refresh when an appointment is taken. Both platforms can support real-time use cases, though the implementation and workload will differ.

File storage deserves a little thought, too. Profile photos are one thing; large documents, videos, or thousands of product images are another.

Check storage limits, bandwidth, file access rules, and expected usage before choosing. Built-in storage doesn't mean unlimited uploads or zero operating costs.

6. Scalability and production readiness

A common mistake when choosing a backend is focusing entirely on how many users it can support.

The real question is what those users will be doing. A thousand people occasionally viewing records create a different workload from a thousand people constantly writing data or running complex queries.

Supabase gives you managed PostgreSQL infrastructure, with options to adjust compute resources and support more demanding workloads. PostgreSQL also offers flexibility as your data model and business logic become more sophisticated.

PocketBase is primarily designed around a single-server deployment model. You can increase the resources available to that server, but handling heavier write workloads and distributing work across multiple instances requires more planning.

Its current development status also matters. The official documentation cautions against relying on PocketBase for production-critical applications without being prepared to handle compatibility changes and manual migrations.

This isn't a reason to dismiss it. It is a reason to understand the risks and have a sensible backup and recovery plan.

For an MVP, either platform may be sufficient. For an app that will become central to a business, consider the infrastructure, reliability, and maintenance requirements you'll need over time.

7. Pricing and ongoing costs

PocketBase is free and open source. Supabase offers a free cloud plan and paid plans with higher allowances.

At first glance, PocketBase might look like the cheaper choice. But the software price is only one part of the cost.

With PocketBase, you'll need to account for hosting, backups, monitoring, and the time spent maintaining your server. Depending on your app, you may also need separate services for email delivery or other features.

Supabase's managed cloud service reduces some of that operational work, but usage can incur additional charges as your app grows.

According to the official Supabase pricing page, the Free plan includes 500 MB of database storage per project and 1 GB of file storage. The Pro plan starts at $25 per month. Check the live pricing page before publishing, since prices and allowances can change.

Here's what to consider when comparing the total cost:

• Database, compute, and hosting costs.

• File storage and data transfer.

• Backups and recovery.

• Email delivery and other external services.

• Time spent maintaining and troubleshooting the backend.

If you want to avoid server management, paying for a managed service may be worthwhile. If you prefer controlling your infrastructure and don't mind maintaining it, PocketBase can keep software costs low.

The cheaper option depends on your workload and how you value your own time.

Which Backend Should You Choose for Your First App?

By now, the main differences should be clear. The question is which ones matter for your project.

Choose Supabase if you're building a growing SaaS product

Supabase is a strong choice when your app needs relational data, managed infrastructure, and room for more complex features.

It makes particular sense if you're building:

• A SaaS dashboard with users, teams, and subscriptions.

• A marketplace with connected customer, product, and order records.

• An application with detailed permissions and private user data.

• A product that needs database queries, authentication, and storage in one platform.

For example, a multi-tenant SaaS app with team workspaces and role-based permissions is a natural fit for PostgreSQL and Supabase's managed services.

Choose PocketBase if you want a lightweight, self-hosted backend

PocketBase may be the better fit when your data model is straightforward, and you prefer to keep your backend compact.

Consider it for:

• A small internal business tool.

• A prototype with a simple data model.

• A lightweight booking or content app.

• A project where self-hosting and infrastructure control are priorities.

Just make sure you're comfortable maintaining the server and working within PocketBase's current limitations.

Choosing a Database for an AI-Built App

An AI builder can help you create an app faster, but you still need to decide where your data lives and how your app accesses it.

That choice depends on what you're building. Supabase is worth considering when you need a PostgreSQL database, relational data, and managed backend services. PocketBase may be a better fit for a smaller application where a lightweight, self-hosted backend makes sense.

The same decision matters when building with AI. You should consider your data model, authentication requirements, hosting setup, and plans for future growth before choosing a backend.

Fregio takes a browser-based approach to building websites, web apps, and SaaS products. You can choose a Next.js instance and connect supported tools, including Supabase or PocketBase, as part of your build. Muse helps wire the pieces together, while your database choice still depends on your application's requirements.

Can You Switch from PocketBase to Supabase Later?

Yes, but moving from one to the other takes more than copying your database.

PocketBase and Supabase use different database systems and APIs, so you'll need to account for those differences during migration.

Here's what the process typically involves:

1. Restructure your data. Map PocketBase collections and fields to PostgreSQL tables, columns, and relationships.

2. Export and import records. Transform fields and data types where necessary, then verify the imported data.

3. Handle authentication separately. User records, passwords, tokens, and active sessions may require special migration steps. Don't assume they can be copied directly.

4. Recreate access rules. Replace PocketBase API rules with appropriate Supabase permissions and RLS policies.

5. Update the application. Change API calls, SDK usage, queries, and file-storage references as needed.

6. Test before switching over. Check sign-in, permissions, uploads, and essential workflows before moving users to the new backend.

For a small app, migration can be manageable. For a mature product with multiple integrations and complex business logic, it can take considerably more work.

If you already know your app needs PostgreSQL, starting with Supabase may save you a migration later. But if PocketBase meets your current needs, you don't have to overengineer an early project just because it might grow.

Frequently Asked Questions

Is Supabase better than PocketBase for beginners?

Supabase can be easier if you want managed hosting and several backend services in one place. PocketBase may feel simpler if you're comfortable running a lightweight application yourself. The better choice depends on whether you prefer avoiding server maintenance or keeping control of your own infrastructure.

Is PocketBase cheaper than Supabase?

PocketBase is free and open source, but you still need to pay for hosting and account for maintenance. Supabase offers a free cloud plan, with its Pro plan starting at $25 per month according to its current pricing page. Compare the full cost of hosting, storage, backups, and maintenance before deciding.

Can PocketBase handle a production app?

PocketBase can work for applications whose requirements fit its architecture, but its official documentation warns that backward compatibility isn't guaranteed before version 1.0. It advises against production-critical use unless you're comfortable managing manual migration steps. Review its current guidance and plan for backups and recovery before deploying an important application.

Which scales better: Supabase or PocketBase?

Supabase offers managed PostgreSQL infrastructure and more options for scaling a growing application. PocketBase is primarily designed around a single-server deployment and vertical scaling. Actual performance depends on your queries, workload, infrastructure, and concurrency, so test your own application rather than relying on a fixed user-count threshold.

Can I use Supabase or PocketBase with an AI-generated app?

Yes, if your chosen AI app builder supports the required integration or lets you configure the necessary application code. You'll still need to verify the database connection, authentication, permissions, and backend logic. An interface that looks finished doesn't necessarily mean the application is securely connected to a working backend.

Should I start with Supabase or PocketBase for an MVP?

Choose Supabase if your MVP needs relational data, managed hosting, and a foundation for more complex features. Consider PocketBase if your project is lightweight and you're comfortable managing its infrastructure. The right choice is the simplest backend that meets your actual requirements without creating avoidable security or maintenance problems.

Final Verdict: Supabase vs PocketBase

Supabase and PocketBase can both help you get an app off the ground. They simply suit different needs.

If you're building a SaaS product with connected data, detailed permissions, and growth plans, Supabase is a strong starting point. If you want a compact backend for a smaller project and prefer managing your own hosting, PocketBase is worth considering.

You don't need to predict every feature your app will ever have. But you should understand where its data will live, how you'll protect it, and what maintaining the backend will involve.

Choose the backend that fits the product you're building now, without making the next stage of development harder than it needs to be.
