i3-gaps is a fork of i3wm, a tiling window manager for X11. It is kept up to date with upstream, adding a few additional features such as gaps between windows.

i3 is a tiling X11 window manager that dynamically manages tiled, stacked, and tabbed window layouts.

i3 primarily targets advanced users. Windows are managed manually and organised inside containers, which can be split vertically or horizontally, and optionally resized.

i3 uses a plain-text configuration file, and can be extended and controlled from many programming languages.
