Managing System and Marketplace Apps
An app is a separately installed component that extends the basic Confluence functionality.
Not to be confused with the Confluence mobile app that users install on their own device, these apps are installed by a Confluence admin, and act like an extension to Confluence. They are also known 'plugins' or 'add-ons'.
There are two main types of apps:
- System apps - these are bundled with Confluence and provide core functionality
- User installed apps - these are usually downloaded from The Marketplace and may have been created by Atlassian or by a third party developer.
For information about developing your own apps for Confluence, see the Confluence Server and Data Center Developer documentation.
About the Universal Plugin Manager
System and Marketplace apps are managed via the Universal Plugin Manager (known as the UPM). The UPM can be found in most Atlassian applications, and provides a consistent experience for administering apps. To visit the UPM, go to 
> Manage apps in the Confluence header.
The UPM allows you to:
- Discover and install new apps from the Atlassian Marketplace.
- Install or remove apps.
- Configure app settings.
- Enable or disable apps and their component modules.
- Confirm app compatibility before upgrading Confluence.
You'll need Confluence Administrator permissions to access the UPM.
See Request Marketplace Apps for information on how users can find and request add-ons.
See the Universal Plugin Manager documentation for more information on using the UPM.
Disable and uninstall apps
You can disable or unsubscribe from user installed apps that are no longer being used on your site. See Disabling and enabling apps to find out how to do this.
Once the app is disabled, its features are immediately unavailable. If the app included macros, pages that contained those macros will show an 'unknown macro' error. To avoid this, you can check which macros are being used on your site before disabling an app by checking the macro usage statistics.
Go to 
> General Configuration > Macro Usage.
