GitLab API: Repository projects/branches basic reporting tool

Dear community,

I would like to use API to have a quick overview for all of my projects, a sort of report which would list them and highlight active branches and the last commit date, for example.
Before developing my own tool, as I don’t like to reinvent the wheel, I was wondering if you are aware of a nice Browser plugin, or stand-alone application, or anything else which calls the GitLab APIs and returns a basic report.
