Add-ons, also known as plugins, add extra functionality to your Atlassian Cloud apps. From managing versioned documentation to creating mockups and wireframes, there's a whole range of possibilities. Add-ons are added to each Atlassian Cloud app, individually. Check out the documentation for your app(s), below. 1. JIRA Applications – Managing Add-ons 2.

Visit the marketplace to see what's available; you can filter by the Atlassian app you're using, or just go ahead and search for something. You can also reach the marketplace via the "Find New Add-ons" screen in the Administration section of Jira applications or Confluence.
