You can view the packages and projects that depend on a repository in the Dependents graph.
The Dependents graph contains data on both packages and applications. Packages are repositories that contain a library in a package manager, whereas applications are repositories that depend on the selected repository. The list of applications in the Dependents graph is sorted by the most recent project that depends on the repository.
Note: The Dependents graph only contains data for Ruby gems and doesn't include data for other languages or Git submodules.
Accessing the Dependents graph
On GitHub, navigate to the main page of the repository.
