I don't see how it's possible to support Linux with Wayland, unless you limit the automation only to the browsers.

https://github.com/patrickjaja/claude-desktop-bin seems to be trying hard to but I haven't tried it.

There's this thing called Windows.

I don't like it, and I'm sure you don't either, but it's not a Mac. Or a Linux. And it's what most actual desktop users are stuck with, still.
