KWin is KDE's X window manager and in the process of becoming a Wayland compositor. It is the default window manager of the KDE Plasma 4 and KDE Plasma 5, but it can also be used on its own or with other desktop environments.

KWin can be configured by scripting, using QML or QtScript, both of which are based on ECMAScript.[3]
