My first idea was to use the Gitea instance of the Free Software Foundation Europe, but T&Cs strongly encourage only projects with direct relation to the FSFE activities, so personal projects don’t seem welcome.
The first-party Gitea platform seems to be in risk of becoming for-profit.
Selfhosting Forgejo is a good solution, especially since federation via ActivityPub will be available soonish.
Codeberg is nice (and will join the federation), but they are getting a bit too big and are having some scaling problems.
I am also working on a Forgejo code hosting site over at https://f-hub.org but it isn’t really open for public yet (I am willing to on-board people interested in contributing to running the site though). The idea is to launch it together with the availability of the Forgejo federation.
Sounds pretty intresting, link to a discussion?
