For a low-tech version of this, I have long had an alias (which I call "nerdwars") to "git shortlog -ns --no-merges" which just gives the number of commits by contributor from most to least. It's a good way to get a sense for who the major contributors in a project are.

Number of commits is not a very good metric to measure contributions. It would only work when there is an agreed style of commits and everyone sticks to that. Number of blame lines per contributor would be overall much more accurate, and immune to different styles of committing (e.g. squashed mega-commits vs rebased self-contained commits).
