Eike’s lovely new terminal Kwi depends on the latest releases of ghostty-vt library. This means you should probably build it yourself as distros will often be slower than Eike. :)

Ghostty is written in Zig, but it supports cmake and is, therefore, buildable by kde-builder, just add the following lines to your kde-builder.yaml:

project ghostty:
    repository: https://github.com/ghostty-org/ghostty.git

It surprises me how many non-KDE projects I have in my kde-builder.yaml every time I open it.
