Repo Remover helps you quickly and easily archive, or delete multiple GitHub repos with a single click. Your repos are listed in a table which can be filtered, sorted, and searched. All you need to do is select the repos, choose the action, and click a button!
Just found this and used it. A really smart implementation. I am cautious of online scripts, etc, if you are remember to revoke the token when you’re done deleting.
