I think it’s just the ease of GUI for people. This isn’t to shit on anyone, btw. A lot of people don’t like dealing with the keys and IPs involved, few as there may be, with setting up wireguard.
If someone else has a compelling difference or reason to use tailscale then I’d be happy to hear it. I tried it once and it worked fine enough. But wireguard works just as fine and takes the same time to setup if you already know what to do. Like wireguard seriously takes 2 minutes.
I was using Heimdall and it was having some weird corruption(?) issues. Switched to homarr when I saw it the other day and it’s great. It has small icons (for phones) medium (for like tablets) and large (for desktops/laptops) all can be changed independently so you can optimize for mobile and desktop usage. Très bien
