There is a fairly straightforward feature in Forgejo to sync your repos to Github, if that's what you want to do. It's not perfect, of course, but should help to advertise your projects and keep your activity heatmap green.

I mostly use Forgejo for my private repos, which are free at Github, but with many limitations. One month I burned all my private CI tokens on the 1st due to a hung Mac runner. Love not having to worry about this now!
