Applications
============

An application in |software_prod_name| is defined by a single Helm\* chart with predefined runtime configurations or profiles.

The Helm chart and Applications requirements that must be fulfilled for deployment and management using |software_prod_name|, see :doc:`/user_guide/package_software/app_requirements`.

View Applications
~~~~~~~~~~~~~~~~~

To view the **Applications** page, click the **Deployments** tab and then click **Applications** on the left menu.
On the **Applications** page, you can view the list of applications and the available registries.
You can search for applications and registries using the search bar at the top of the page. The other actions you can perform from this page are editing, viewing details, and deleting an application.

Applications are partitioned into two tabs:

*   **Applications** - Displays the list of user provided applications that are available for deployment.
    (The list is empty until a user adds an application)
*   **Extensions** - Displays the list of system provided extensions that are available for deployment.
    (The list is populated with many preconfigured applications. You cannot add or delete applications from this list).
