Firebase is Google's application development platform, providing a suite of backend services for building web and mobile apps. It includes Cloud Firestore and Realtime Database for data storage, Firebase Authentication for user sign-in, Cloud Storage for files, Cloud Functions for serverless backend code, and Firebase Hosting for static and dynamic web content. Firebase AI Logic adds direct access to Gemini models for building AI-powered features.

Firebase serves individual developers, startups, and enterprises building web and mobile applications. It uses a two-tier pricing model: the no-cost Spark plan and the pay-as-you-go Blaze plan, which retains all Spark quotas and adds usage-based billing plus access to more services. Firebase integrates tightly with Google Cloud Platform and Android and iOS tooling, and is one of the most widely used backend-as-a-service platforms.
