Supabase vs Firebase: Which Backend for Your App?
Supabase is an open-source backend built on PostgreSQL (SQL), with predictable plans: Free, then Pro from $25/month. Firebase is Google’s backend built on NoSQL databases, free on Spark and pay-per-use on Blaze. Choose Supabase for relational data, SQL and less lock-in; Firebase for mobile-first apps deep in Google’s ecosystem. Compared by Kode Studio, Hyderabad.
| Supabase database | PostgreSQL — relational, SQL, joins |
|---|---|
| Firebase database | Cloud Firestore / Realtime Database — NoSQL documents |
| Supabase pricing | Free; Pro from $25/month; Team from $599 |
| Firebase pricing | Spark (free, limits); Blaze pay-as-you-go per read/write/storage |
| Open source | Supabase yes (self-hostable); Firebase no |
| AI builders | Lovable and Bolt commonly use Supabase |
What they are
Both are “backend as a service” platforms: they give your app a database, user logins, file storage, serverless functions and realtime updates without you managing servers. Supabase wraps a full PostgreSQL database with auto-generated APIs. Firebase, owned by Google, offers document databases (Firestore and the Realtime Database), plus authentication, hosting, cloud functions, analytics, crash reporting and push notifications.
Feature comparison
| Supabase | Firebase | |
|---|---|---|
| Database model | Relational (tables, SQL, joins) | NoSQL (documents and collections) |
| Queries | Full SQL, views, functions | Limited query patterns, denormalised data |
| Auth | Email, phone, OAuth, magic links | Email, phone, OAuth, anonymous |
| Security | Postgres row-level security | Security rules |
| Realtime | Yes | Yes, very mature |
| Mobile extras | SDKs for Flutter, Swift, Kotlin | Push notifications, Crashlytics, Analytics built in |
| Self-hosting | Yes | No |
Pricing models compared
Supabase uses plans. Free gives 500 MB database and 50,000 monthly active users but pauses inactive projects; Pro starts at $25/month with 8 GB database, 100,000 MAUs and a spend cap. Full detail: Supabase pricing.
Firebase has the free Spark plan with daily limits, and the Blaze pay-as-you-go plan billed per document read, write and delete, storage and network. Small apps often cost little or nothing; badly designed queries that read thousands of documents per screen can produce surprising bills. Set budget alerts in Google Cloud.
Which fits your data?
Relational data → Supabase
Orders with line items, invoices with GST, products with variants, users with roles, bookings tied to staff and branches. SQL joins and reports are natural.
Document data → Firebase
Chat messages, activity feeds, user profiles and settings, and apps where each screen loads one document. Realtime sync is effortless.
Most business apps in India — billing, CRM, ecommerce, school or clinic management — are relational, which is why we usually recommend SQL.
Lock-in and portability
Supabase is open source and built on standard PostgreSQL, so you can export your database and run it anywhere, or self-host Supabase itself. Firebase is proprietary; moving off Firestore means rewriting data access and transforming documents into tables. If long-term control matters, Supabase has the edge.
For mobile apps
Firebase remains very strong for Android and iOS: Cloud Messaging for push notifications, Crashlytics, Analytics and Remote Config are widely used — even in apps whose main database is elsewhere. A common combination is Supabase or a custom API for data, plus Firebase for push and crash reporting. See Flutter vs React Native.
Supabase and AI app builders
Lovable, Bolt and similar tools commonly generate apps on Supabase. Before launching such an app, check row-level security policies, move the project into a company-owned account on Pro, and set up backups. See what is Lovable.
How to decide
Answer these before writing code.
You'll need: A list of your app’s main screens and data
Sketch your data
If it looks like spreadsheets with relationships, lean Supabase.
List mobile needs
Push, crash reporting and analytics favour adding Firebase services.
Estimate usage
Count reads per screen and daily users to estimate Firebase costs.
Consider reporting
Business reports and GST summaries are far easier in SQL.
Check team skills
Pick what your developers can secure and maintain.
A third option: your own API and database
For many Indian business apps, a conventional backend — PHP or Node.js with MySQL or PostgreSQL on a VPS — is simplest and cheapest over time, with no per-user or per-read pricing. It requires developers to build login, APIs and security, which BaaS platforms give you ready-made. We choose between all three based on the project.
Get the backend right from day one
Kode Studio in Gachibowli, Hyderabad builds web and mobile apps on Supabase, Firebase and custom backends, and rescues AI-built apps with security problems. Custom web apps start from ₹34,499.
Performance for users in India
Both platforms let you choose a region. Pick one close to your users — Mumbai or Singapore regions are common choices for Indian apps — because every database call travels that distance. For Supabase, the region is chosen when you create the project and cannot easily change later. For Firebase, Firestore’s location is also fixed at creation. Getting this right at the start avoids slow screens on mobile data.
Verdict: Supabase or Firebase?
Business apps with relational data, reports and predictable bills → Supabase.
Mobile-first, realtime-heavy apps using Google services → Firebase (or Firebase for push and analytics alongside another database).
Long-term control and lowest running cost → consider your own API on a VPS.
Frequently asked questions
Is Supabase better than Firebase?
For relational business data and SQL, often yes. Firebase is stronger for mobile tooling and simple realtime documents.
Is Supabase free?
Yes, with limits; projects pause after a week of inactivity. Pro starts at $25 a month.
Is Firebase free?
The Spark plan is free with limits; the Blaze plan charges per use.
Can I migrate from Firebase to Supabase?
Yes, but documents must be reshaped into tables and app code updated.
Which is better for Flutter apps?
Both have Flutter SDKs. Choose based on your data model; Firebase adds strong push and crash tools.
Does Lovable use Supabase?
Lovable commonly uses Supabase or Lovable Cloud for logins and data.
