The closest to your dream is probably https://hexos.com/
It is closed source, but build on top of open source...
They (for now) have a one time purchase license, no subscription.
It has buddy backups. Can run on any normal x86 pc / server (you have to bring your own and install hexos to it). And has a nice and simple GUI for deploying services easily.
I never personally used it. I just have it on my radar. For me, the not so easy but fully free (cost) and open source way works reasonably well. I run my homelab with dokploy.
lol no. I used this one for a month and no.
It works but it has the most convoluted GUI possible. No backup system at all iirc. And running arbitrary containers was a nightmare that is not even integrated with the GUI.
I settled on https://dokploy.com/
