Mutter is a window manager initially designed and implemented for the X Window System, and recently has evolved to be a Wayland compositor. It became the default window manager in GNOME 3, replacing Metacity which used GTK+ for rendering. Mutter uses a graphics library called Clutter giving it OpenGL capability. The name is a portmanteau of Metacity and Clutter.
Mutter can function as a standalone window manager for GNOME-like desktops and serves as the primary window manager for the GNOME Shell, which is an integral part of GNOME 3. Mutter is extensible with plugins and supports numerous visual effects. GNOME Shell is written as a plugin to Mutter. Gala, a core component of the Pantheon desktop environment, is built using libmutter. Budgie-wm, used in the Budgie desktop environment, is another window manager built on libmutter.

Muffin is a fork of Mutter by the Linux Mint team for their Cinnamon desktop environment. Cinnamon's shell, a fork of GNOME Shell, is written as a plugin for Muffin.
