How Apps Become Available to Your Customers

The list of apps available to a customer depends on various factors,
such as the service plan settings, the Application Vault configuration,
and so on. Moreover, service providers are able to forbid accessing apps
for all Plesk users. If you do not adjust the app availability, your
customers will see all apps from Application Catalog and all apps you
uploaded to the Vault.

To view the list of apps available to a certain customer, go to the
Applications section > All Available Applications. Before an app
becomes available in the app list of a certain customer, it passes
through a series of filters. The app is filtered on the following
levels:

1. Application Vault.
   Plesk lets you toggle the availability of APS packages you have
   uploaded to the Vault. Note that this works only for your own
   packages: There is no way to control the availability of apps
   downloaded from the Catalog. Learn more about apps management in the
   Managing Apps with the Application Vault section.
2. Service plan.
   Plesk allows you to specify what apps to include in a certain service
   plan. The filter affects all customers with this service plan.
3. Subscription.
   If you want to select the apps available to a particular customer,
   update the apps list in the respective subscription.

The resulting app list is available to your customers.
