Firebase is a Backend-as-a-Service (BaaS) platform developed by Google that provides tools for building, managing, and scaling web and mobile applications.
Firebase offers real-time databases, user authentication, cloud functions, push notifications, analytics, and more — all integrated into a single developer-friendly platform. It’s especially popular for startups and MVPs looking to move fast without building a backend from scratch.
Its Firestore database enables real-time syncing, and Firebase Auth simplifies user login with providers like Google, Facebook, and Apple. With built-in hosting, testing tools, and CI/CD support, Firebase is often used for rapid prototyping and scalable apps.
