All [Unix like systems](https://en.wikipedia.org/wiki/Unix) with either [X11](https://en.wikipedia.org/wiki/X_Window_System) or [Wayland](https://en.wikipedia.org/wiki/Wayland_(protocol)) are well supported since ever.
Over the years it was, like most of the [KDE applications](https://apps.kde.org/), ported to various [BSD](https://en.wikipedia.org/wiki/Berkeley_Software_Distribution) variants.
Be it some mainstream Linux distribution like [Fedora](https://fedoraproject.org/) or a niche one like [NixOS](http://nixos.org), Kate is available as binary package.
Since several years there are activities in the KDE community to provide our libraries and applications for [Windows](https://en.wikipedia.org/wiki/Microsoft_Windows).
Even if that is a non-free platform, we can reach out to new users and developers that might later be then even interested to switch a full open platform.
We have Kate and some other applications in the official [Windows Store](https://apps.microsoft.com/search/publisher?name=KDE+e.V.) and nightly build for more of them.
With reasonable effort you can develop Kate on Windows with [Craft](https://community.kde.org/Get_Involved/development/Windows).
We have nighly build available for that and you can, like on Windows, develop Kate with the help of [Craft](https://community.kde.org/Get_Involved/development/Mac).
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](https://kate-editor.org/get-it/).
One recent topic that needs love is the removal of DBus for Windows/macOS/Android and other systems that don't use that normally.
If you are up to help with that, [here](https://invent.kde.org/packaging/craft-blueprints-kde/-/issues/17) that is coordinated.
Just don't get that wrong, DBus is great on the Linux or BSD systems that use it natively, but it is a pain on systems that have no notion of DBus and leads there to hangs or the spawning of unwanted processes.
