I use GitLab at work and Forgejo at home. GitLab is huge, Forgejo is lighter. GitLab Runner is very nice, Woodpecker was a pain to setup but it now does everything I need. GitLab supports subgroups, Forgejo does not. Forgejo is FOSS with a non-profit behind it, GitLab Inc. is for-profit.

At the end, I like to work with both. GitLab has lots of features, but for my own stuff Forgejo serves me very well and I like the openness of it.
