Firebase is Google's comprehensive backend-as-a-service (BaaS) platform providing real-time databases, authentication, cloud functions, hosting, and analytics for web and mobile apps. It enables developers to build and scale apps without managing servers, using Firestore (NoSQL document database), Firebase Auth, Firebase Storage, and Cloud Functions. Firebase is especially popular for mobile apps and real-time collaborative applications.
