I built a bitbucket cloud add-on that would compare your PR’s against others in the same repository, repositories or globally to see if they were smaller or larger than average. Would also display the number of files, lines changed and what languages.

Annoyingly there is no pay via atlassian for bitbucket cloud yet, and I was not prepared to do my own pay,ent which sort of negates the marketplace value.

It’s something I plan to launch when that is released eventually though.
