Amethyst is a tiling window manager for macOS that automatically arranges application windows into non-overlapping layouts, inspired by xmonad.
Amethyst solves the problem of manual window management on macOS by automatically tiling windows to fill the screen without overlap. It brings the keyboard-driven workflow of xmonad to macOS, allowing users to control window positioning and sizing through configurable keyboard shortcuts rather than mouse dragging. The tool uses macOS accessibility APIs to monitor and rearrange windows according to tiling layout algorithms.
Amethyst suits developers and power users who work with multiple applications simultaneously and prefer keyboard-centric workflows. It works best for those already familiar with tiling window managers on Linux or who want to replicate that experience on macOS. The tool requires macOS 10.15 or later and must be granted accessibility permissions to function. Users should be aware that certain macOS settings, particularly the automatic Space rearrangement feature in Mission Control, can interfere with predictable keyboard navigation and should be disabled for optimal use. Configuration is handled through keyboard modifier combinations and command mappings, with sensible defaults provided but full customization available.
The project maintains active engagement with user-reported issues and troubleshooting documentation. Development activity shows consistent attention to macOS compatibility as the platform evolves, with updates addressing new system requirements. The maintainer responds to bug reports and feature requests from the community, indicating ongoing stewardship of the codebase.
