> As far as I know, Phabricator does not let you view or comment on individual commits in a code review (which I use at work). Let me know if you know differently and I might switch to doing that.

Isn't there a "commits" tab when viewing a revision? Also Phabricator is no longer maintained for the last year.

> Can you advise me on running CI on each commit in the PR in GitHub? As far as I can see, it's technically possible in that you can run arbitrary code as part of your CI, but there's no convenient way to do it. (In particular, I would want to be able to view the CI runs for each individual commit, i.e. render the little checkmark/x next to each commit in GitHub, which seems like it would require a lot of integration via the API.)

You'd use the https://docs.github.com/en/rest/commits/statuses API to publish the little checkmark. More info: https://docs.github.com/en/pull-requests/collaborating-with-....

However, before you do that, consider: this one I think is a slight impedance mismatch between how users conceptually think about using GH and how GH actions are designed to be triggered. The most simple thing to do if you want every commit checked and tested is just make a GH action that runs your checks on push, which gets run on every commit and updates the status. If you already have a push action, just remove the "main" branch restriction. The PR action is designed to do PR-scoped things. You can, if you really only want to check commits once they are opened for PR, iterate over the commit list and manually trigger workflows to test and check each one (you can even just manually trigger your existing push action if you add the manual trigger option and specify the commit sha yourself and it will run, I think). But, is the list of commits that get pushed to the repo and the list of commits you want to eventually test for inclusion into main really that different, at the end of the day?
