Youtrack

Gerrit, it's way better for code review

Also Youtrack, but other software exists that's specific for this, I have seen Confluence used a lot and while I don't recommend: that's usually the case.

As far away from code as possible, right now it's Zulip

Youtrack, though usually in companies they use Jira for this.

In proper tools that are designed to solve a specific need, not try to do everything: badly.

Now, a sane person will respond to me with the fact that I haven't removed any single points of failure, I've actually just added more of them. They'd be right! The differences is that it makes the stack a bit more flexible and composable. Migration of, say, the Wiki, doesn't make major issues because it's already somewhat decoupled.
