Google had a code hosting service (free for open source projects) with repo, issue tracker, and wiki. But it was shut down in 2016.

Coincidentally, Google is shutting down Google Source repositories in GCP today. https://cloud.google.com/source-repositories/docs

A new google tombstone would be super exciting indeed

Remember Google Code?

That's just taking it out back and shooting it with extra steps.

Yeah, uh, no. They'll just kill it like everything else. https://killedbygoogle.com/
