Web service that allows you to have remote import paths for
import "project.example.com/package"
The key benefit is that your packages are independent of the version control system provider, whether it is GitHub, GitLab, Bitbucket or private repository. You can change provider or even version control system whenever you like, and also keep the same import paths. Also, custom domains means better branding of your packages.
