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.
I can give it a shot, certainly. One of the main contributors behind it is in my RSS reader so there’s some name recognition there. Future pricing is not final though, so I can’t budget for it before committing.
