Best window manager for Mac (2026): how to choose

Start with how you work, not with a feature list

Mac window managers fall into three families. Snappers (Rectangle, Magnet, Moom, Loop) move a window to a half, a third or a saved spot when you ask. Tilers (AeroSpace, yabai, Amethyst) arrange every window automatically by dividing the screen. Scrolling managers (Paneru, Ribbon, ChainYourMac, LanesMac, OmniWM) put windows side by side on a strip that runs past the screen edges, so opening a window never shrinks the others.

If you mostly use one or two apps at a time, a snapper is enough. If you're a keyboard-first developer who likes config files, a tiler fits. If you keep many windows open and hate them shrinking, try scrolling.

The question most guides skip: what happens when you dock?

If you plug a MacBook into a monitor, your window manager's real test is the moment you connect or disconnect. macOS moves windows around when displays change, and most managers simply leave the mess for you to fix. Moom can tie saved layouts to display arrangements if you set them up. Transom's Desks do it automatically: each set of displays gets its own remembered layout, restored when that set comes back.

Quick picks

Free and simple snapping: Rectangle. Cheapest App Store snapper: Magnet. Hand-built saved layouts: Moom. Free i3-style tiling: AeroSpace. Maximum scripting (with SIP trade-offs): yabai. Pure scrolling: Ribbon, ChainYourMac or LanesMac (paid), Paneru or OmniWM (free).

Snap on your laptop, a scrolling strip on your external monitor, and layouts that survive docking: Transom. It's the one we make, so weigh that, and try it free for 14 days.

Things to check before you buy any of them

Does it need System Integrity Protection disabled? (Most don't; yabai's advanced features do.) Does it offer a trial or refund? Is it notarized by Apple? When was the last update? Does it handle dialogs and native tabs without wrecking your layout?
