The App Catalog is a specialized site collection within SharePoint Online and SharePoint Server that enables organizations to store and manage custom applications (apps) that can be deployed across their SharePoint environment. The App Catalog provides a centralized location for app deployment, management, and distribution.

Key Features

• Storage for Apps: The App Catalog serves as a repository for both SharePoint-hosted and provider-hosted apps, as well as SharePoint Framework (SPFx) solutions.

• Deployment Across Sites: Once an app is uploaded to the App Catalog, it can be made available for use across multiple site collections within the tenant.

• Version Management: Administrators can manage different versions of apps, allowing for updates and rollbacks as needed.

• Approval Workflow: Organizations can set approval workflows to control which apps can be added to the App Catalog.

• Customization Control: The App Catalog enables control over which apps are accessible to users, ensuring that only approved and vetted applications are used within the environment.

Best Practices
