Backend as a Service OAuth 2.0

Firebase REST API

Google's mobile and web app development platform

Firebase is Google's comprehensive app development platform that provides backend services including real-time databases, authentication, cloud storage, hosting, and serverless functions. Developers use Firebase to build scalable web and mobile applications without managing infrastructure, leveraging its real-time synchronization, automatic scaling, and integrated analytics to rapidly develop and deploy production-ready applications.
