And all these tools struggle with incremental code reviews for some reason. There are currently two options: 1. Add new commits to an existing branch. Any reviewier always needs the context from the earlier commits. 2. Overwrite the whole branch (force push). Older comments, and generally the delta between different versions of the change request, get lost or are at least very hard to see (e.g., might get mixed with changes from a rebate). Working with the patch/commit as artifact (as, e.g., Gerrit does it) seems so much more usable for code review that I can only speculate why no big tool offers it. Presumably, it requires too much internal knowledge about git to implement the backend correctly.
