How to Decide

Amethyst is a free, open‑source tiling window manager for macOS that developers and power users adopt for keyboard‑driven window layout control. The alternatives split into a few clear camps: Magnet leans on a paid one‑time price and simple drag‑to‑snap UI for fast window snapping; AeroSpace emphasizes a free, open‑source license with deep keyboard‑centric customization and fast, efficient tiling for developers and designers.

When weighing replacements for Amethyst, focus on (1) licensing and cost – whether the tool is free/open source like AeroSpace or requires a purchase like Magnet, (2) the depth of customization and scripting – AeroSpace offers extensive keyboard‑driven configuration while Magnet provides fixed snap presets, (3) the learning curve and UI complexity – Magnet’s drag‑and‑drop approach is low‑friction compared to the more script‑heavy setup of Amethyst and AeroSpace, and (4) multi‑monitor handling – both alternatives support multiple displays, but the granularity of per‑screen layout control can differ and may affect workflow.
