Using Supabase as a Firebase Alternative: A Modern Developer Guide

Looking for a Firebase alternative? Discover why Supabase is becoming the go-to open-source backend for modern app development. Real-time database, auth, and more.

🔥 Introduction

If you’re a developer building modern web or mobile apps, chances are you’ve heard of Firebase. It’s been a dominant player for real-time databases, auth, and backend-as-a-service (BaaS). But now, there’s a rising star: Supabase.

In this article, we’ll compare Supabase with Firebase and help you decide whether it’s the right backend solution for your next project.

🧱 What is Supabase?

Supabase is an open-source Firebase alternative that uses PostgreSQL under the hood. It provides features like:

Real-time database
Authentication
Storage
Edge functions (like Firebase Cloud Functions)
RESTful and GraphQL APIs

Think of it as the open-source version of Firebase — but SQL-first and developer-friendly.

🆚 Supabase vs Firebase: Feature Comparison

Feature	Firebase	Supabase
Database	Firestore (NoSQL)	PostgreSQL (SQL-based)
Open-source	❌ Closed-source	✅ Fully open-source
Real-time Support	✅ Yes	✅ Yes
Auth System	✅ Firebase Auth	✅ Supabase Auth (Email, OAuth)
Pricing	Free tier + pay-as-you-go	Generous free tier + affordable
Hosting	Firebase Hosting (integrated)	No built-in hosting (use Vercel/Netlify)
Ecosystem	Mature, large community	Growing rapidly

🚀 Why Developers Are Switching to Supabase

✅ 1. SQL Over NoSQL

Supabase uses PostgreSQL, which means:

You can use SQL queries (yay!)
Better data modeling
Joins, views, triggers — full relational power

✅ 2. Real-Time Out of the Box

Supabase enables real-time updates using Postgres’ replication system. Just subscribe and watch data change live.

supabase
  .from('todos')
  .on('INSERT', payload => console.log('New todo:', payload))
  .subscribe();

✅ 3. Open Source + Self Hosting

Use their hosted version
Or deploy Supabase on your own VPS for complete control

✅ 4. Auth Made Easy

Email/password, magic link, and OAuth (Google, GitHub, Apple) support is built-in.

💰 Monetization Tip: Use Supabase in Your SaaS

If you’re planning to build a SaaS product, fitness tracker, todo app, or freelancing platform, Supabase gives you:

Backend scalability
Auth and role-based access control
Real-time interactions (chat, updates)
Secure API access

👉 Example: At AB Web Tech, we use Supabase to build lightweight MVPs for clients fast and affordably.

📦 Integrating Supabase in Your App

🔧 With React

Install:

npm install @supabase/supabase-js

Initialize:

import { createClient } from '@supabase/supabase-js';
const supabase = createClient(SUPABASE_URL, SUPABASE_ANON_KEY);

Use:

const { data, error } = await supabase.from('users').select('*');

🔒 Is Supabase Secure?

Yes. It offers:

Row-Level Security (RLS)
JWT-based auth
Fine-grained access policies

You can write SQL rules like:

CREATE POLICY "Only allow owner"
  ON todos
  FOR SELECT
  USING (auth.uid() = user_id);
