KDE KWin Script for snapping windows into zones. Handy when using a (super) ultrawide monitor, an alternative to PowerToys FancyZones and Windows 11 snap layouts.
The zone selector is a small widget that appears when you drag a window to the top of the screen. It allows you to snap the window to a zone regardless of the current layout.
The zone overlay is a fullscreen overlay that appears when you move a window. It shows all zones from the current layout and the window will snap to the zone you drop it on.
Create multiple layouts and cycle between them.
KZones comes with a set of shortcuts to move your windows between zones and layouts.
By using the same colors as your selected color scheme, KZones will blend in perfectly with your desktop.
Install via KDE Store or clone this repo and run the ./build script.
Under System Settings / KWin Scripts / Get New Scripts, search for KZones and install it.

Make sure you have "zip" installed on your system before building.
git clone https://github.com/gerritdevriese/kzones
cd kzones && ./build
The zone selector is a small widget that appears when you drag a window to the top of the screen. It allows you to snap the window to a zone regardless of the current layout.
- Enable or disable the zone selector.
- Set the distance from the top of the screen at which the zone selector will start to appear.
The zone overlay is a fullscreen overlay that appears when you move a window. It shows all zones from the current layout and the window will snap to the zone you drop it on.
- Enable or disable the zone overlay.
- Choose whether the overlay should be shown when you start moving a window or when you press the toggle overlay shortcut.
- Choose where the cursor needs to be in order to highlight a zone, either in the center of the zone or anywhere inside the zone.
The script will remember the geometry of each window when it's moved to a zone. When the window is moved out of the zone, it will be restored to it's original geometry.
- Enable or disable this behavior.
You can define your own layouts by modifying the JSON in the Layouts tab in the script settings, here are some examples to get you started:
Single layout
[
{
"name": "Layout 1",
"padding": 10,
"zones": [
{
"name": "1",
"x": 0,
"y": 0,
"height": 100,
"width": 25
},
{
"name": "2",
"x": 25,
"y": 0,
"height": 100,
"width": 50
},
{
"name": "3",
"x": 75,
"y": 0,
"height": 100,
"width": 25
}
]
}

]The main array can contain as many layouts as you want:
Each layout object needs the following keys:
name: The name of the layout, shown when cycling between layoutspadding: The amount of space between the window and the zone in pixelszones: An array containing all zone objects for this layout
Each zone object needs the following keys:
x,y: position of the top left corner of the zone in screen percentagewidth,height: size of the zone in screen percentage
Stop certain windows from snapping to zones by adding them to the filter list.
- Select the filter mode, either Include or Exclude.
- Add window classes to the list seperated by a newline.
You can enable debug mode to see the window class of the active window.
The polling rate is the amount of time between each zone check when dragging a window. The default is 100ms, a faster polling rate is more accurate but will use more CPU. You can change this to your liking.
When debug mode is enabled, the script will log more information and show extra information in the overlay.
List of all available shortcuts:
| Shortcut | Default Binding |
|---|---|
| Move active window to zone | Ctrl+Alt+[0-9] |
| Move active window to previous zone | Ctrl+Alt+Left |
| Move active window to next zone | Ctrl+Alt+Right |
| Switch to previous window in current zone | Ctrl+Alt+Down |
| Switch to next window in current zone | Ctrl+Alt+Up |
| Cycle between layouts | Ctrl+Alt+D |
| Toggle zone overlay | Ctrl+Alt+C |
To change the default bindings, go to System Settings / Shortcuts and search for KZones
- Check if your KDE Plasma version is at 6 or higher (for older versions, check the releases)
- Make sure there is at least one layout defined in the script settings and that it contains at least one zone.
- After changing settings, you need to reload the script by disabling, saving and enabling it again. This is a known issue with the KWin Scripting API.
- Make sure your compositor is enabled, as it is needed to draw transparent windows.
- You can find this setting in Plasma settings: Display and Monitor - Compositor
