I use umbrel. It’s probably not the most secure or private and it’s kind of stupid to use because most everything I host is in Portainer.
But it’s nice to use because it handles all the network side and it’s all GUI. I would recommend it because it will give you a confidence boost, but you’ll quickly realize it’s not usable with many of the regular installable apps because you can’t customize them enough.
Portainer is like a GUI docker app afaik and I use AI to help customize the docker compose files. I do host a few things that are installable from the Umbrel appstore.
Some of my favourite things that I host are an onion service Monero node, a snowflake proxy, and Ente Photos.
I might switch to proxmox at some point because I imagine it has better security, but it would probably be a lot of learning when I already have a functioning setup.
