bug.n review
Free window tiling with customizable layouts, app rules, and saved sessions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
bug.n is an open-source tiling window manager add-on for the Windows Explorer shell. It automatically resizes and positions windows, with tile, monocle, and floating modes. Its combination of configurable layouts, tagged views for virtual desktops, and saved sessions suits Windows users who want direct control over a multi-window workspace without a paid plan.
Layout controls cover dimensions, axes, master-area size, and gaps, while application and window-class rules can determine management, floating, and decoration behavior. Multi-monitor window and view management is available, and sessions can preserve monitors, views, layouts, and window state. Hotkeys and a command GUI provide control; an optional status bar displays window and system information. AutoHotkey is the listed integration, so bug.n is a focused Windows tool rather than a cross-platform workspace manager.
The software is distributed as a ZIP archive with an executable, source code, and documentation, and requires no installation process. It is free and open source. One important maintenance consideration is that the repository identifies stable v9 as no longer actively developed or maintained. That makes bug.n a fit for Windows users who value configurable tiling and session persistence and are comfortable with its maintenance status. Those seeking actively maintained software or support beyond the listed controls should consider another window manager.
