Which type of user can do everything to the application, including publish, export, and delete?

An Administrator has full control over an application within Appian, which includes the ability to publish, export, and delete the application. This role is responsible for managing all aspects of the application lifecycle, ensuring that the application is properly maintained, deployed, and updated as necessary. Administrators have the highest level of permissions and can carry out administrative tasks that users in other roles, such as Editors and Viewers, cannot perform.

Editors can make changes to the application and manage its contents, but they do not have the privileges to delete the application or handle publication processes in the same comprehensive manner as an Administrator. Viewers can only access and examine the application without the ability to make modifications or manage settings. Deny is not a valid user type in the context of application permissions within Appian, as it implies a lack of access rather than a defined role. Thus, the Administrator role is essential for performing all necessary functions related to application management.
