About
Cloud Functions for Firebase is a serverless backend platform that lets developers run application logic without provisioning or managing servers. It supports event-driven execution from Firebase products, HTTPS requests, the Admin SDK, and Cloud Scheduler jobs.
The service is designed to help teams build secure, scalable backend workflows for mobile and web apps. Functions can respond to database changes, authentication events, analytics conversions, and other triggers while remaining isolated from client-side code.
- Event-driven functions for Firebase and Google Cloud triggers
- Managed serverless execution environment
- Automatic scaling based on demand
- Support for JavaScript and Python functions
- Private server-side logic that is not exposed to clients
