I am new to this space, but I think dokploy is another service of this kind: https://dokploy.com/

Has anyone experience with it?

This is really cool and I will definitely try it out! Am I missing something or is there really no contributors license agreement?

Well thats what backups are for, but may be start with a mirror or with unimportant stuff for at least a year ;) Also proprietary service can delete your data, too. This happens especially when you are using the generous free tier and they decide to make more money. See Evernote, Gitlab, Heroku…
