Halves & thirds
Snap the focused window to the left, right, top, or bottom half — or to thirds, including left and right two-thirds.

windex
A macOS window manager with grid-based snapping and smooth animations, written in Rust. windex lives in the menu bar and lets you snap the focused window to halves, thirds, and quarters — or push it to another monitor — entirely from the keyboard.
What it does
Every Window, One Keystroke Away
Quarters & corners
Send a window to any corner of the screen with a single shortcut for tidy four-up layouts.
Maximize & center
Fill the screen or drop a window neatly into the middle without reaching for the mouse.
Multi-monitor
Move a window to the next or previous display and keep working across every screen.
Smooth animations
Windows glide into place with a short, configurable easing curve instead of snapping instantly.
Menu bar & TOML config
Runs quietly from the menu bar with no dock icon. Every hotkey is remappable through a simple TOML file.
Keyboard first
Default Shortcuts
| Action | Shortcut |
|---|---|
| Left / right half | ⌃⌥ ← / → |
| Top / bottom half | ⌃⌥ ↑ / ↓ |
| Left / center / right third | ⌃⌥ D / F / G |
| Left / right two-thirds | ⌃⌥ E / T |
| Corners (TL, TR, BL, BR) | ⌃⌥ U / I / J / K |
| Maximize | ⌃⌥ Enter |
| Center | ⌃⌥ C |
| Move to next / previous monitor | ⌃⌥ N / P |
Every binding is remappable through a TOML config file, so the defaults are only a starting point.
Under the hood
How It's Built
Written in Rust
A single native binary — small, fast, and dependency-light — built with the Rust toolchain and shipped with a one-command installer.
macOS Accessibility API
windex moves and resizes other apps' windows through the system Accessibility API, the same foundation the built-in window controls use.
Configurable easing
An animation engine tweens each window into position with adjustable duration and easing, so movement feels deliberate rather than abrupt.
