Welcome to Firebase!

Firebase is Google's platform for building apps fast. Think of it as a complete managed backend: auth, databases, file storage, and more.

Why Choose Firebase?

Firebase wins on speed: ready-made backend services, Google-run infrastructure that auto-scales, real-time sync, and one SDK across web, iOS, and Android.

Firebase Authentication

Firebase Authentication handles sign-up and sign-in for you — email, phone, and social providers like Google or Facebook — with no backend auth code.

Realtime Database

The Realtime Database is a cloud NoSQL store that holds your data as one JSON tree and syncs every change to all connected clients instantly.

Cloud Firestore

Cloud Firestore is Firebase's newer NoSQL database. Versus Realtime Database it adds richer queries, better scaling, and a collections-and-documents model.

Cloud Storage

Need to store photos or videos? Cloud Storage for Firebase is scalable object storage you can read and write straight from client code, securely.

Firebase Hosting

Building for the web? Firebase Hosting serves your content over a global CDN with free SSL and custom domains, so you deploy worldwide in minutes.

How Services Work Together

Firebase's real power is integration: Auth guards your database, Storage URLs live in Firestore docs, and Hosting pairs with Cloud Functions.

Your First Code Snippet

You will write Firebase code soon, but first the basics of how a program runs. Here is a minimal Java entry point — Firebase SDKs plug into structures like this.

public class Main {
  public static void main(String[] args) {
    System.out.println("Hello, CoddyKit!");
  }
}

Core Services Check

Firebase offers a wide array of services to accelerate app development. Which of the following is NOT typically considered a core backend service provided by Firebase?

Your Firebase Journey Begins

Nice work! You explored the Firebase ecosystem — Auth, Realtime Database, Firestore, Storage, and Hosting. Next: set up your first project.
