When looking at a Github repository of a certain user you can look at the number of commits, when each commit was made and what files were added or changed.

Is there a tool that can aggregate this data of multiple Github repositories of a certain user and present this data in an overview?

The overview could look something like this:

It doesn't have to be in a spreadsheet format, this is just to give an example of the kind of data I would like to represent.

Is there a tool that does this or would I be better off creating my own tool that does this with the Github API?

The repositories I want to analyze are all set to public.
