The latest release is out on all of the platforms.
Change notes:
The GUI executables are an experiment that I think is somewhat interesting. The Windows tildefriends-gui.exe and Linux AppImages all run like a local app using an embedded browser, very similarly to the mobile version. I couldn't get the MacOS version working in time, but that might be in the cards, too. The Linux version has some glibc / gtk dependencies which make it not guaranteed to just work, but they're pretty old, so I expect they will.
There are also .debs and docker containers available.
As always, feedback is welcome on all things.
