# Applications

Applications let you group related projects together so you can view aggregated quality metrics across multiple repositories. For example, you might create a "Web App" application containing your frontend, backend, and shared library projects, or a "Mobile App" application grouping your iOS and Android repositories.

<Note>
  Applications are disabled by default. To enable this feature, go to **Settings > Features** and
  toggle **Applications** on.
</Note>

The **Applications** tab is visible in your workspace's top navigation alongside Projects.

## Creating an Application

Create applications from **Settings > Applications** or from the **Applications** tab. Each application has a name (required) and an optional description.

## Assigning Projects to an Application

Assign a project to an application from the project's **Settings > General** page using the **Application** dropdown.

Each project can belong to at most one application. Select **None** to unassign.

## Viewing Application Metrics

The **Applications** tab in your workspace displays a table of all applications with aggregated metrics across their assigned projects:

| Column              | Description                                                           |
| ------------------- | --------------------------------------------------------------------- |
| **Application**     | The application name (click to view its projects)                     |
| **Projects**        | Number of projects assigned to the application                        |
| **Size**            | Aggregated codebase size                                              |
| **Maintainability** | Maintainability grade (A through F) with estimated remediation effort |
| **Duplication**     | Percentage of duplicated code across the application                  |
| **Security**        | Security rating with count of security issues                         |
| **Coverage**        | Code coverage percentage with a letter grade                          |

Clicking an application name takes you to the **Projects** view filtered to show only that application's projects.

You can search applications by name using the search bar, and sort by any column.

## Managing Applications

Applications are disabled by default. Workspace administrators can enable the feature from **Settings > Features** by toggling **Applications** on.

Edit or delete applications from **Settings > Applications** by clicking the application name.

<Warning>
  An application cannot be deleted while it still has projects assigned to it. Unassign all
  projects first.
