I haven't found anything off-the-shelf that helps. I manage a project with > 50k repositories in a GitHub organization. For the past few years I've been developing software that helps with my [particular goals](https://github.com/gitenberg-dev/gitberg https://github.com/gitenberg-dev/gitberg), but I'm afraid there isn't much there that may help you.
