Manage apps from your app dashboard
When you first log into share.streamlit.io you will land on your app dashboard, which gives you a list of all your deployed apps. This list does include apps deployed by other developers in your workspace, since you're all managers of those apps. Such apps are indicated with an icon like this one:
App workspaces
Streamlit Cloud is organized into workspaces, which automatically group your apps according to the corresponding GitHub repository's owner. If you are part of multiple repositories, then you will have multiple workspaces.
If an app's GitHub repository is owned by you, the app will appear in your personal workspace, named "<YourGitHubHandle>".
If an app's GitHub repository is owned by an organization (such as your company), the app will appear in a separate workspace, named "<GitHubOrganizationHandle>".
