What is Firebase?

Firebase is a platform by Google that provides the backend infrastructure most apps need — authentication, databases, file storage, hosting, push notifications, analytics, and serverless functions — without requiring you to build or manage any of it yourself.

Key Firebase Services

Firebase Authentication handles user sign-up and login with email/password, phone number, Google, Apple, Facebook, and other providers. It manages sessions, tokens, and security automatically.

Cloud Firestore is a NoSQL document database that syncs data in real time across all connected clients. When one user updates data, every other user sees the change instantly. This makes it ideal for chat apps, collaborative tools, and live dashboards.

Cloud Functions lets you run backend code in response to events (a user signs up, a document changes, an HTTP request arrives) without managing servers. Functions scale automatically and you pay only for execution time.

Cloud Storage stores and serves user-generated content like images, videos, and documents with built-in security rules.

Firebase Hosting provides fast, secure hosting for web applications with a global CDN, automatic SSL, and one-command deploys.

When to Use Firebase

Firebase works best for apps that need rapid development, real-time features, and moderate scale. It is ideal for MVPs, startup apps, chat applications, social platforms, and internal business tools. For complex enterprise applications with advanced querying needs or strict relational data requirements, a custom backend with PostgreSQL or a similar database may be more appropriate.
