We use GitHub Enterprise where I work now. I do sometimes do stacked PRs but GHE does not make it easy. The rebasing and merge conflict resolution can be a headache although git rebase —onto helps a lot.
I previously worked somewhere that used Phabricator. Its “stacked diffs” worked great. I’d use it all the time when working on complex, multipart changes.
Try out the linked tool git-branchless (https://github.com/arxanas/git-branchless, I'm the author). It should help you restore Phabricator-like workflows. In particular, check out the `git sync`, `git restack`, and `git move` commands for handling rebasing and conflict resolution.
