Supabase vs Firebase comparison

Introduction

Supabase and Firebase help you build apps faster by managing your data and backend services without writing too much code.

You want a ready-to-use backend for your mobile or web app.

You need real-time data updates in your app.

You want to store and manage user accounts easily.

You prefer open-source tools or want a managed service.

You want to choose between SQL and NoSQL databases.

Syntax

Supabase

Supabase and Firebase are platforms, not code syntax. You use their services via APIs and dashboards.

Supabase uses PostgreSQL (a SQL database) and open-source tools.

Firebase uses a NoSQL database and proprietary Google services.

Examples

Supabase uses SQL commands to query data, while Firebase uses JSON documents.

Supabase

Supabase: SQL queries to manage data
Firebase: JSON-like NoSQL data structure

Supabase lets you host your backend or use their cloud, Firebase is only cloud-hosted.

Supabase

Supabase: Open-source, self-host or managed
Firebase: Fully managed by Google

Sample Program

Both examples get all user records but use different methods and data structures.

Supabase

1. Supabase example: Fetch all users
const { data, error } = await supabase.from('users').select('*')

2. Firebase example: Fetch all users
const snapshot = await firebase.firestore().collection('users').get()
snapshot.forEach(doc => console.log(doc.data()))

Important Notes

Supabase is great if you like SQL and want open-source flexibility.

Firebase is good if you want a simple NoSQL database and tight Google integration.

Both offer authentication, real-time updates, and storage but differ in technology and pricing.

Summary

Supabase uses SQL and is open-source; Firebase uses NoSQL and is Google-managed.

Choose Supabase for SQL familiarity and flexibility.

Choose Firebase for easy setup and Google ecosystem integration.
