Sway is a tiling window manager and Wayland compositor, inspired by i3, and written in C. Sway is designed as a drop-in replacement for i3 using the more modern Wayland display server protocol and wlroots compositor library. Sway werk met bestaande i3-konfigurasielêers en ondersteun die meeste van i3 se kenmerke terwyl dit verskeie nuwe kenmerke van sy eie bied.
