How do I find my project URL in GitLab?

Once you set up a project in GitLab, it is given a default URL automatically. The default format of the website is namespace.example.io. The namespace is your username under the GitLab account or the group name in which you created this project. In contrast, example.io is your instance's page domain. Use the prescribed information to extract the project URL. Moreover, GitLab supports custom domains but only under HTTP and HTTPS serving. So, if you're using a custom domain, that will also alter your project domain URL.
