I'll look for a tool that mirrors all my repositories (i.e. only forks). If I can't find one, I'll write it myself.
Very similar to yours, but also does forks, which I’m not sure yours does by a quick glance at your readme. Although, mine doesn’t automatically mirror from another forge, just clones everything locally. I’ll have to add a TODO to add mirroring.
Please have a look at how I handle them and consider adding a link to my project in your “similar tools” section, and I’ll do the same for you!
I just looked over your project, and it seems pretty cool. A little bit different than mine, since mine is specifically github to a gitea mirror repository. I don't mind adding a link to your project in mine.
Thanks for sharing!
