GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
It would be nice, if there was user-agent shown on main torcheck page.
For example: https://torcheck.xenobite.eu/
It would be quite useful, I think.
