Benefit from high responsiveness and low latency with our scalable, multi-region architecture and CDN support.

Cloud Functions

Add server-side business logic using Cloud Code Functions

Add business logic to your application using JavaScript functions that seamlessly integrate with Back4app features like database and authentication. Cloud Functions can be triggered by changes in your app's data, user sign-ups, or API calls, offering even more flexibility and control.

What are serverless functions?

Install new NPM modules to extend the capabilities of your Cloud Functions and enable external integrations.

Schedule Cloud Functions to handle recurring tasks such as sending engagement emails, push notifications, or performing data sanitization.

Run your backend code without the hassle of server management. Cloud Functions are single-purpose JavaScript functions executed in a secure, scalable, and managed Node.js environment.

APIs & SDKs

Easily integrate your app with GraphQL, REST APIs, and SDKs

Fetch data from your application using GraphQL, REST, or your preferred SDK. Build your backend in minutes with automatically generated APIs that provide endpoints for all operations, making it easy to interact with backend features using just a few lines of code.
