Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

subtle is a free, open-source manual tiling window manager for Linux systems using X11. It is aimed at users who want direct control over window placement rather than a primarily automatic tiling workflow. Its core model divides screens into configurable placement slots called gravities, while tags associate windows with virtual desktops called views. Floating, fullscreen, sticky, and resizable modes provide alternatives when tiled placement is not appropriate.

The standout feature is its configurable control model. Keyboard and mouse action mappings let users define how they interact with windows, while tag-based rules can place windows automatically according to their tags. Ruby scripting and an extension API add another layer for customization, and the command-line client supports window management outside the main interface. These options make subtle a strong fit for technically inclined Linux users who want a window manager they can adapt through configuration, scripts, and commands.

Its platform scope is focused: subtle targets Linux with X11, and multihead setups are supported through Xinerama and XRandR. The built-in system tray and extensible panel add desktop conveniences, while support for EWMH and ICCCM helps it work with relevant window-management standards. Distributed under the GNU GPLv2 license, it is available as free and open-source software. Choose subtle if configurable manual tiling, scripting, views, and command-line control matter most. Users seeking deeper automatic tiling or a platform beyond Linux X11 should consider an alternative.
