That’s an interesting service. It’s essentially what DH does for click-once installs, but Cloudron has current apps which (sorry) DH notoriously does not. I really wish DH would simply go through their list of click-once apps and remove anything that’s over a year old as a potential security issue if nothing else. It’s a dis-service to people to offer old software since it doesn’t have current features or fixes. Perhaps that’s the price someone pays for convenience but I think that’s like feeding a homeless person catfood - it’s perhaps as much a dis-service as a service.
Anyway, Cloudron looks interesting, but yeah, it requires root, it makes DNS changes, and it requires 1GB of RAM. You’re not going to be able to use that in DH shared space or even VPS. If you’re sophisticated enough to use DreamCompute then I dare say you’re already beyond the need for a click-once solution.
My advice: Installing software isn’t tough. Get familiar with the process. Learn. Grow. After you’ve done it a few times with different software you’ll have skills that will make it easier to do more and you’ll feel less of a need for click-once convenience tools.
