What is Supabase?
Supabase is an open-source backend-as-a-service (BaaS) platform that bundles a PostgreSQL database, authentication, file storage, real-time subscriptions, and serverless edge functions into one cohesive package. Often described as the open-source Firebase alternative, Supabase has quickly become the backend of choice for developers building modern web and mobile applications.
According to Hackceleration's 2026 review, Supabase's documentation is exceptional — among the best available. Every feature has multi-framework examples covering React, Vue, Next.js, Flutter, and React Native, along with interactive code playgrounds and video tutorials.
PostgreSQL Database
Full-featured relational database with foreign keys, joins, indexes, and the power of SQL.
Authentication
Email, OAuth, magic links, and SSO with Row Level Security for fine-grained access control.
File Storage
S3-compatible storage with CDN, image transformations, and resumable uploads.
Real-time
WebSocket subscriptions that push database changes to clients instantly.
Edge Functions
Serverless TypeScript functions that run close to users for low latency.
AI & Vectors
Built-in pgvector for embeddings, enabling semantic search and AI-powered features.
Why Supabase for Mobile Apps?
When searching for the best mobile app builder software, backend capabilities are often overlooked. Yet 85% of app failures begin in the backend, according to Jellyfish Technologies. Supabase addresses this by providing a complete, production-ready backend that scales with your app.
Predictable, Lower Costs
Supabase charges by storage and bandwidth, not by read/write operations like Firebase. According to ClickIT's comparison, this makes costs 4-5x more predictable for most mobile apps. The average Pro plan user spends $35-75/month for production workloads.
Open Source = No Vendor Lock-in
Supabase uses standard PostgreSQL, meaning you can export your data anytime or self-host if needed. This is crucial for businesses that need control over their infrastructure. As Zapier notes, using Firebase comes with proprietary vendor lock-in that makes migration difficult.
SQL Power for Complex Data
Mobile apps often have complex data relationships — users, orders, products, reviews. PostgreSQL handles this naturally with foreign keys and joins. Firebase's NoSQL approach requires denormalization and multiple queries, adding complexity to your app code.
Native Mobile SDKs
Supabase provides official SDKs for React Native, Flutter, Swift, and Kotlin. The supabase-js library works seamlessly in Expo projects, making it the natural choice for the best AI app builder for mobile apps that use these frameworks.
Supabase vs Firebase for Mobile Apps

|---|---|---|
| Database | PostgreSQL (relational) | Firestore (NoSQL) |
| Open Source | ✓ Yes | ✗ No |
| Self-Hosting | ✓ Available | ✗ Not possible |
| Pricing Model | Storage + bandwidth | Read/write operations |
| Free Tier MAUs | 50,000 | Varies by service |
| Vector/AI Support | ✓ Native pgvector | Via extensions |
Essential Backend Features for Mobile Apps
Before selecting a backend, it helps to understand what features your mobile app actually needs. According to CMARIX research, 53% of users abandon apps that take too long to load, making backend performance critical. Here are the essential components every mobile app backend should provide.
Database
Store and organize your app data with relationships, queries, and indexes.
PostgreSQL with auto-generated REST & GraphQL APIs
Common Use Cases
All 5 features included in every Supabase project — no additional configuration needed.
How Natively Handles Backend Complexity
With Natively, you connect to a Supabase project and the AI handles the rest. Simply provide your project URL and API key, describe what you want to build, and Natively generates production-ready React Native code that integrates with your database, authentication, cloud storage, and edge functions. No backend coding required.
How AI App Builders Integrate with Supabase
The rise of AI-powered development tools has transformed how mobile apps connect to backends. According to Itransition's 2026 statistics, by 2026 low-code development tools are projected to account for 75% of new application development, up from 40% in 2021. AI builders take this further by generating production-ready code automatically.
Traditional Integration
- ✗Write custom API integration code
- ✗Configure authentication flows manually
- ✗Handle error states and edge cases
- ✗Set up file upload handling
- ✗Implement real-time subscriptions
AI Builder Integration
- ✓Connect with URL + API key
- ✓Auth flows generated automatically
- ✓Error handling built-in
- ✓File uploads work out of the box
- ✓Real-time features included
Platforms like Natively exemplify this new approach. When you connect your Supabase project, the AI understands your database schema and generates appropriate queries, mutations, and subscriptions. You describe features in plain English — "add a profile page with user photo upload" — and the AI creates the necessary code to interact with Supabase storage and database.

Frequently Asked Questions
What is Supabase and why use it for mobile apps?
Supabase is an open-source backend-as-a-service platform built on PostgreSQL that provides database, authentication, real-time subscriptions, storage, and edge functions. It is ideal for mobile apps because it offers a generous free tier, predictable pricing, automatic API generation, and native SDKs for React Native and Flutter. Over 4.5 million developers now use Supabase, with major companies like Mozilla and 1Password relying on it.
How do AI app builders integrate with Supabase?
Modern AI app builders like Natively integrate with Supabase by automatically generating code that connects to your Supabase project. You simply provide your Supabase URL and API key, and the AI handles database queries, authentication flows, file uploads, and real-time subscriptions. This means you can describe your app in plain English and get a fully functional mobile app with a production-ready backend.
What backend features do mobile apps need?
Mobile apps typically need: a database for storing user data and app content, authentication for user sign-up and login, file storage for images and media, real-time updates for live features, and serverless functions for custom backend logic. Supabase provides all of these in one integrated platform, eliminating the need to cobble together multiple services.
Is Supabase better than Firebase for mobile apps?
Supabase offers several advantages over Firebase for mobile apps: it uses PostgreSQL which provides more powerful querying and data relationships, it is open-source so you can self-host and avoid vendor lock-in, and pricing is more predictable since it charges by storage rather than read/write operations. Firebase may be better for apps that need real-time sync out of the box or are deeply integrated with Google services.
How much does Supabase cost for a mobile app?
Supabase offers a free tier with 500MB database storage, 1GB file storage, 50,000 monthly active users, and unlimited API requests. The Pro plan starts at $25 per month and includes 8GB database, 100GB storage, 100,000 MAUs, and email support. Most small to medium production apps cost between $35-75 per month once usage fees are included.
