KWin

What is KWin?

KWin manages windows and compositing in KDE Plasma, handling window placement, resizing, and visual effects. It has been part of KDE since the 3.x era and is mature, stable, and deeply integrated with the desktop environment. Unlike standalone utilities, it’s a core system component that enables modern desktop behavior on Linux.

It's for users running KDE Plasma who want fine control over window behavior, animations, and desktop effects. Most beneficial to those already in the KDE ecosystem, especially power users tweaking their workflow or aesthetics. It’s not a standalone tool like PowerToys but a foundational part of the desktop.

Compared to PowerToys, KWin feels more integrated but less modular. PowerToys offers discrete utilities you can toggle on or off; KWin’s features are built-in and managed through system settings. You don’t get a 'PowerToys-like' overlay menu, but you do get smoother, lower-level control over window management and visuals.

Best for: KDE Plasma users who want deep window management and visual control.

Tips for Windows users

If you're used to PowerToys, know that KWin’s features are accessed through System Settings > Window Management, not a floating toolbar. Tiling works similarly but uses different shortcuts—default is Meta+Arrow keys. Window rules and effects are more powerful but less discoverable. You’ll need to adjust expectations: KWin isn’t a collection of add-ons, but a core part of how KDE works.
