A free, open-source macOS window manager that replaces the Rectangle/Magnet hotkey grid with a radial menu. Hold a trigger key, move the cursor toward the half, quarter, or edge you want, release to commit.

Hold the trigger key and Loop pops a translucent radial menu over the active window. Move the cursor toward a half, quarter, or edge; release to commit. A live preview outlines the destination frame as you aim, so a wrong flick can be corrected before the resize fires.

Rectangle and Magnet ask you to memorize a grid: a chord per position, more chords as you add halves, thirds, and quarters. The chord is symbolic — you have to remember which modifier you mapped to “left third.” Loop’s gesture is the position. A “cycles” feature lets you re-flick in the same direction to step through halves → thirds → quarters without picking new keys for each.

The radial menu, preview, and theming are tunable (width, shape, color, padding); a stash gesture tucks a window to a screen edge for quick recall. Per-app behavior and keyboard shortcuts are still there for people who want both. GPLv3, Swift, signed and notarized, macOS 13+.

The trade-off versus a grid-based manager is a day or two of muscle-memory rebuild — flicking is fast once it’s in your hands, but coming from a decade of ⌃⌥← makes the first afternoon feel slower. Free, with no nags or telemetry.
