For non-technical users I could see freedombox (or sandstorm.io) being useful, but if you have enough knowledge to manage a vm + use docker-compose, the flexibility is much better.
Wont more apps be supported in freedombox? maybe it does not allow plugins?
I can support any app that I have either the source for, or a binary. I just write my own docker images [0] if one doesn't exist already on dockerhub, or install the binary directly on a VM or LXC as needed. For example, I set up Jellyfin on its own LXC.
For me, stuff like freedombox/sandstorm directly limit me as I would have to spend time learning their GUI, etc, for no gain. All I need is an ssh session into my docker VM and I can set up pretty much anything I need exactly how I want. This lets me be very particular about services accessing files, networking, versioning, and so on.

None of these services are useful apparently, because I manage them myself instead of relying on something like sandstorm/freedombox.
