Firebase vs PocketBase: Key Differences and When to Use Each

Firebase is a cloud-based backend platform by Google offering extensive services like real-time database, authentication, and hosting. PocketBase is a lightweight, open-source backend you can self-host, focusing on simplicity and local control with real-time sync and built-in auth.

Quick Comparison

Here is a quick side-by-side look at Firebase and PocketBase across key factors.

Feature	Firebase	PocketBase
Type	Cloud service by Google	Open-source self-hosted backend
Database	Cloud Firestore & Realtime Database	SQLite-based with real-time sync
Authentication	Built-in with many providers	Built-in with email/password and OAuth
Hosting	Managed hosting for web apps	No hosting, self-hosted backend
Real-time Sync	Yes, with Firestore and Realtime DB	Yes, with live queries
Pricing	Free tier + pay-as-you-go	Free, open-source, hosting costs apply

Key Differences

Firebase is a fully managed cloud platform that handles scaling, security, and global availability for you. It offers multiple database options like Firestore and Realtime Database, plus integrated services such as analytics, messaging, and hosting. This makes it ideal if you want a ready-to-use backend without managing servers.

PocketBase, on the other hand, is a lightweight backend you run yourself. It uses a simple SQLite database with real-time sync and built-in authentication. You get full control over your data and hosting environment, which is great for small projects, prototypes, or when you want to avoid vendor lock-in.

Firebase supports many authentication providers out of the box and integrates deeply with Google Cloud services. PocketBase supports basic auth and OAuth but requires more manual setup for advanced features. Firebase's pricing is usage-based, which can grow with your app, while PocketBase is free but you pay for your own hosting.

Code Comparison

Here is how you add a new user record with email and password in Firebase using JavaScript.

javascript

import { initializeApp } from 'firebase/app';
import { getAuth, createUserWithEmailAndPassword } from 'firebase/auth';

const firebaseConfig = {
  apiKey: 'YOUR_API_KEY',
  authDomain: 'YOUR_AUTH_DOMAIN',
  projectId: 'YOUR_PROJECT_ID'
};

const app = initializeApp(firebaseConfig);
const auth = getAuth(app);

async function registerUser(email, password) {
  try {
    const userCredential = await createUserWithEmailAndPassword(auth, email, password);
    console.log('User registered:', userCredential.user.uid);
  } catch (error) {
    console.error('Error registering user:', error.message);
  }
}

registerUser('[e-mail]', 'password123');

Output

User registered: <user-uid-string>

PocketBase Equivalent

Here is how you add a new user with email and password in PocketBase using JavaScript.

javascript

import PocketBase from 'pocketbase';

const pb = new PocketBase('http://127.0.0.1:8090');

async function registerUser(email, password) {
  try {
    const user = await pb.collection('users').create({
      email: email,
      password: password,
      passwordConfirm: password
    });
    console.log('User registered:', user.id);
  } catch (error) {
    console.error('Error registering user:', error.message);
  }
}

registerUser('[e-mail]', 'password123');

Output

User registered: <user-id-string>
