Atlassian Forge

Forge is Atlassian’s serverless app development platform, designed to make it possible to build an app in a few hours, with hosting, multiple development environments, and API authentication built-in. Forge can be used to build custom apps and integrations or apps distributed through the Atlassian Marketplace.

Forge apps are fully hosted by Atlassian. Atlassian automatically creates the development, staging, and production environments for these apps. The user can write a single function and it will run, reducing the amount of code needed to write and operate an app.
