I thought this was pretty cool when I found out about it. It turns out you can set this variable and run Qt programs using different Qt Platform Abstractions.

export QT_QPA_PLATFORM=vnc
some-qt-program

Now it will run as a VNC server, so you could run it headless for example and connect to it with any VNC client. There are other cool plugins such as linuxfb to run it without X on the Linux framebuffer.

See https://doc.qt.io/qt-6/qpa.html#qpa-plugins for available plugins.
