Kate editor on all platforms
Unix like systems with X11 or Wayland All Unix like systems with either X11 or Wayland are well supported since ever. Linux with X11 and now Wayland is for a long time the primary system on that Kate work happens. Over the years it was, like most of the KDE applications, ported to various BSD variants. Be it some mainstream Linux distribution like Fedora or a niche one like NixOS, Kate is available as binary package.
Same as for Windows, if you like to try that, use the nighly installer for either ARM or Intel Macs linked on the Kate website. One recent topic that needs love is the removal of DBus for Windows/macOS/Android and other systems that don’t use it normally. The current state is already sufficient that the nightly builds of Kate no longer hang on e.g. macOS, but still some frameworks like KIO will need more work.
