When you build a full stack application, you need both a frontend and a backend. You also need a database, an authentication system, and tools to store files or run server functions. Firebase, made by Google, has been a popular choice for these tasks. But now, more developers are turning to Supabase, an open-source alternative that is easy to use, flexible, and perfect for full stack development.
In this blog, we’ll explain what Supabase is, how it compares to Firebase, and why it’s a great choice for full stack developers. If you’re new to full stack development or want to build apps faster, this guide is for you.
Supabase is also becoming more popular among students who join a full stack developer course. Learning modern tools like Supabase can help you build real-world apps with fewer headaches.
What is Supabase?
Supabase is an open-source platform that helps you build and run backend services for web and mobile apps. It includes everything a full stack developer needs:
- A PostgreSQL database
- Authentication (sign up, login, social login)
- Realtime updates
- File storage
- Edge functions (serverless code)
Supabase is often called “the open-source Firebase” because it offers similar features but uses open standards. You can host it yourself or use their hosted version.
Why Developers Like Supabase
There are many reasons why developers prefer Supabase, especially those building full stack apps:
- Open Source
Unlike Firebase, Supabase is open-source. This means you can see the code, customize it, and even host your own version. You are not locked into a closed system.
- Uses PostgreSQL
Supabase uses PostgreSQL, a powerful and trusted relational database. If you already know SQL, it’s easy to work with. You can also use tools like pgAdmin or TablePlus to manage your data.
- Easy Authentication
You can add user login, signup, and even social logins (like Google or GitHub) with just a few lines of code. Supabase also includes email verification and password recovery.
- Realtime Data
With Supabase, your app can get live updates when data changes in the database. This is great for chat apps, dashboards, or any app that needs live data.
- File Storage
Supabase includes a simple file storage system. You can upload images, videos, or documents, and control who can access them.
- Serverless Functions
You can run backend logic using Supabase Edge Functions. These are small bits of code that run on the server when needed, without setting up your own server.
Supabase vs Firebase
Let’s look at some simple differences between Supabase and Firebase:
| Feature | Supabase | Firebase |
| Database | PostgreSQL | Firestore (NoSQL) |
| Open Source | Yes | No |
| Self-hosting | Yes | No |
| SQL Support | Full SQL | No SQL (uses own syntax) |
| Realtime Support | Yes | Yes |
| File Storage | Yes | Yes |
| Serverless Functions | Edge Functions | Cloud Functions |
| Authentication | Yes | Yes |
Firebase is good for fast development, especially for mobile apps, but Supabase is better for full stack web apps where SQL and open standards matter.
Getting Started with Supabase
Let’s walk through the steps to build a simple full stack app using Supabase. This app will allow users to sign up and add notes to a shared database.
Step 1: Create a Supabase Project
Go to the Supabase website and create an account. After that:
- Click “New Project”
- Choose a name and password
- Supabase will set up your database and project
Once it’s ready, you’ll see your API keys and database URL.
Step 2: Create a Table
Go to the “Table Editor” tab in the dashboard:
- Create a table called notes
- Add the following columns:
- id (type: uuid, primary key, default: uuid_generate_v4())
- user_id (type: uuid)
- content (type: text)
- created_at (type: timestamp, default: now())
Now your backend is ready.
Step 3: Set Up a Frontend
You can employ any frontend framework such as React, Vue, or Next.js. Let’s say you’re using React. First, install Supabase:
npm install @supabase/supabase-js
Then, create a file to set up the Supabase client:
// supabaseClient.js
import { createClient } from ‘@supabase/supabase-js’
const supabaseUrl = ‘YOUR_SUPABASE_URL’
const supabaseKey = ‘YOUR_ANON_KEY’
export const supabase = createClient(supabaseUrl, supabaseKey)
Step 4: Add Authentication
Add a simple form to let users sign in or sign up.
import { supabase } from ‘./supabaseClient’
async function signUp(email, password) {
const { user, error } = await supabase.auth.signUp({
email,
password,
})
if (error) console.log(error.message)
}
You can now build forms to collect emails and passwords, and use this function to sign users up.
Step 5: Add and Fetch Notes
Once a user is signed in, let them add notes:
async function addNote(content) {
const user = supabase.auth.user()
const { error } = await supabase.from(‘notes’).insert([
{ user_id: user.id, content },
])
if (error) console.log(error.message)
}
To fetch notes:
async function getNotes() {
const { data, error } = await supabase.from(‘notes’).select(‘*’)
if (error) console.log(error.message)
return data
}
And just like that, you have a working backend without writing any server code.
Learning tools like Supabase is one of the reasons many developers choose a full stack developer course. These courses often include projects and live demos to help you build real apps with Supabase, Firebase, or other modern tools.
Who Should Use Supabase?
Supabase is great for:
- Beginners learning full stack development
- Developers who want a fast backend
- Teams that prefer SQL over NoSQL
- Projects where open-source and data control are important
- Apps that need authentication and real-time data
If you are building something simple or starting a new project, Supabase will save you time and effort.
Real-Life Use Cases
Here are a few app ideas that work well with Supabase:
- Note-taking apps
- Chat apps
- E-commerce admin panels
- Task trackers
- Portfolios with login sections
- Blog platforms with user accounts
You can build all of these using just Supabase and a frontend framework like React or Next.js.
