The Forge platform
Forge is Atlassian’s cloud app development platform, allowing developers to host apps on infrastructure that is provisioned, managed, monitored, and scaled automatically by Atlassian. Forge provides a complete toolkit for extending Atlassian products.
Forge apps are built in JavaScript; however, the environment differs a little from a traditional Node.js environment. Learn more
Below is a diagram demonstrating the Forge platform architecture.
Forge runtime
At the heart of Forge is a serverless FaaS hosting platform, powered by AWS Lambda. Apps created with Forge run inside a security layer that enforces tenancy isolation and data egress restriction by design.

Forge resolver
The Forge resolver is a function that provides a backend for apps that use UI Kit or Custom UI to implement the user experience of an app. Use of the resolver is optional, but it's useful if you need to run some app logic server-side instead of client-side.

Events
A Forge app can subscribe to events or set up an HTTP endpoint to invoke a function within the app without any user interaction.
Forge storage
Forge's hosted storage lets you store data partitioned by Atlassian product and site. Hosted storage also provides data residency features that allow admins to control where app data is hosted.

Product frontend
Modules are used by Forge apps to extend and interact with Atlassian products.
Forge offers two options for building the user interface of your apps: Custom UI and the UI Kit. Both custom UI and UI Kit apps inherit modern security features to ensure high trust between Atlassian, developers, and users.
Custom UI
Custom UI provides a means of building the user interface of an app from scratch. Custom UI runs within an iframe, providing an isolated environment for the app's interface to be displayed. Learn more about Custom UI
UI Kit
The UI Kit is a flexible declarative language that allows you to build user interfaces across Atlassians products with just a few lines of code. Learn more about the latest UI Kit
Forge bridge
The Product bridge API is a JavaScript API that enables UI Kit and custom UI apps to securely integrate with Atlassian products.

Product APIs
Forge apps can use the Atlassian product REST APIs using the fetch API, a partial implementation of node-fetch.
