tangled.sh is a git collaboration platform built on top of /doro/atproto.
It's quite new, as of today (2025-05-25) it doesn't even support private repositories. But general idea seems pretty promising.
It also supports stacked PR with jj-vcs in mind. This is required to tell people that there is an active feature branch that someone is already working on. If someone edits one of these in collaboration platform, we usually expect some kind of edit history. But I'm not sure if atproto allows it.Contribution
