I have to say I’m not all that into GH[1]. However, if the above is what you want from a review tool I think it meets most, if not all, of those requirements.

[1]I mainly am not a fan of the PR model, GH’s performance if often terrible, availability like a yo-yo, and the UI is not as good as it could be. I’m also not a fan of centralising a distributed tool with a load of vendor lock-in to boot. There are some odd things you can’t turn off (such as PRs) and the issue management is weak, so you have to use something over the top of it for project management such as ZenHub.

SourceHut is more up my street.

Yeah, I didn't mention self-hostability is a must.

SourceHut is terryfying to junior members
