AI-Generated Review

What is magnetism?

Magnetism is a free, open-source macOS window manager written in native Swift. It snaps active windows to halves, quarters, thirds, two-thirds, center, or full screen using customizable keyboard shortcuts or drag-to-edge gestures. Multi-display users get seamless moves between screens, plus restore to previous size and smooth animations—all from a lightweight menu bar app.

Why is it gaining traction?

It mirrors paid Magnet's shortcuts out-of-the-box but ditches the price tag as a free open-source alternative, appealing to devs hunting free GitHub alternatives like free open-source icons or password managers. Drag snapping with live previews and no Electron bloat make it snappier than heavier options, while Homebrew install keeps it dead simple. Early adopters dig the Magnet-compatible workflow without limits.

Who should use this?

macOS devs juggling code editors, terminals, and browsers across dual monitors. Multi-monitor designers or sysadmins resizing windows hourly. Power users ditching Rectangle for more granular thirds/two-thirds snapping.

Verdict

Grab it via Homebrew if you're on Sonoma+ and need a free Magnet clone—features deliver, docs are solid. But with 21 stars and 1.0% credibility score, it's immature; test thoroughly before daily driver status.
