I used Umbrel for a couple of years since one of the first versions, and I still believe it’s a great options for many people.
Unfortunately I’ve some philosophical clash with their current business model, Umbrel started mainly focused on being a bitcoin node alternative, then they started adding other apps, which I think was a great idea. And then they started selling their “own” hardware (or whatever rebranded) and leaving the open source community focus aside, so many things started being tweaked for their own hardware, and the support is now focused mostly on their customers, and not all the users, and I’m not saying that is wrong, it’s just not what I like for myself.
There’re many REALLY BASIC features (like default https support) that hasn’t been solved in those many 5-6 years.
To be clear… I don’t know what you mean with “…what a pitty that Vaultwarden does not find a solution”, Vaultwarden is a very security-focused app, they should enforce security over all as the data you’re storing there is quite important, so ssl/tls/https is totally a MUST for this type of software, the problem is 100% on Umbrel’s side, not Vaultwarden’s.
I agree with you that there should be at least a warning on apps that can’t/won’t be upgraded properly, so it’s the user’s choice to use them or not.
Regarding the alternatives to Umbrel, there’re many options, the most “direct” ones might be Start9 or CasaOS.
In my case I chose to run a bitcoin node on a basic Debian-based device, so nothing too fancy, Raspiblitz or Raspibolt’s guides would do it, Start9 and CasaOS are bitcoin-focused too, that’s why those are the most direct alternatives to Umbrel.
And for the rest of the apps I chose Yunohost, but as I said, Start9, CasaOS, CapRover, etc. are good options too.
