## What it is
Amethyst is an automatic tiling window manager for macOS, inspired by xmonad. It arranges windows into configurable layouts controlled entirely via keyboard shortcuts using the macOS accessibility APIs.

## Use cases
- automatically tile windows on macOS
- manage macOS windows with keyboard shortcuts
- get xmonad-style tiling on a Mac
- organize multiple windows without dragging with the mouse
- cycle through window layouts like tall, wide, and fullscreen
- navigate between macOS Spaces with the keyboard

## When to choose
- you want automatic window tiling on macOS without manual resizing
- you prefer keyboard-driven window management over mouse dragging
- you are familiar with xmonad or other tiling window managers
- you want a free, open-source, actively maintained macOS window manager

## When to avoid
- you are on macOS older than 10.15
- you prefer free-floating, manually positioned windows
- you need a window manager for Linux or Windows
- you cannot grant accessibility permissions to applications
