Replacements
Listings that take over the same core job as COSMIC.
GNOME
Use a Linux desktop organized around an activities overview and workspaces.

KDE Plasma
Use a full Linux desktop with configurable panels, widgets and window behavior.
KDE Plasma provides a full desktop with extensive panel, widget and window behavior settings, and integrates with KDE applications instead of System76's stack.
Cinnamon
Use a Linux desktop with a traditional application menu, panel and system tray.
Cinnamon gives a traditional application menu, panel and system tray with applets and desklets, without COSMIC's tiling workflow.
Xfce
Use a modular desktop environment built around traditional panels and windows.
Xfce is a modular desktop built around traditional panels and windows, with components distributions can combine, and no built-in tiling mode.
Budgie
A free and open source Linux desktop environment with its own panel, application menu and window management.
Budgie is a simple Linux desktop environment with its own panel and application menu, designed to stay out of the way while remaining customisable.
