Auditing GitHub?

Any scripts, tools, methods people are using that they can recommend?

New job expects me to manually audit a very large github org without an enterprise license, or existing scripts.

Under my user I have ~20 Organizations, with 5-600 repo's in each and hundreds of users and teams that I need to audit. I.E Remove teams with no users, remove empty teams, remove teams with no repos attached and the list goes on and on.

I'm by no means a developer but I've looked at the Github API. I dont want to develop a new project or dive down that rabbit hole if I don't have too.

I found Pepper (https://github.com/genuinetools/pepper) but hit my API limit rather quickly.

Looking forward to your input and suggestions! Thanks!
