GlazeWM is currently the darling of the Windows tiling community. Written in Rust, it is fast, lightweight, and configurable via a YAML file. It mimics the behavior of i3—a popular Linux tiler. Windows automatically tile, you can split containers horizontally or vertically, and you navigate with keyboard shortcuts.
Pros: Truly automatic, excellent multi-monitor support, powerful command palette, active development. Cons: Requires editing a config file (no GUI), lacks a system tray icon, basic by default. windows tiling window manager

bug.n is one of the oldest Windows tilers. It is written entirely in AutoHotkey. It functions similarly to the Linux "dwm" (dynamic window manager). It uses "tags" instead of workspaces, which is a more powerful but conceptually different model.
Pros: Extremely lightweight (uses almost zero RAM), highly customizable (edit AHK scripts), supports dynamic tagging. Cons: Looks dated, AutoHotkey syntax is niche, limited non-English keyboard support.
