flingdows
throw your windows around
flingdows is a tiny macOS menu-bar app that gives your windows weight. Drag any window and let go with some speed and, instead of stopping dead, it glides with inertia, slows under friction, and springs back if it overshoots a screen edge — one flick sends it where you want.
It's free and open source under MIT, and the whole feel is yours to tune: fling strength, friction, edge stiffness, and elasticity are live sliders in the menu bar.
how it works
- 01
grant accessibility
Give flingdows Accessibility access so it can move windows.
- 02
fling a window
Drag any window and release with speed — it glides and settles on its own.
- 03
tune the feel
Adjust strength, friction, and elasticity from the menu bar until it feels right.

Ways to use flingdows, and how it compares.
- comparisonLooking for a free Mac window manager? flingdows is free and open sourceMost Mac window managers cost money or paywall the good parts. flingdows is free and MIT-licensed, and it adds something none of the paid ones have: throw a window and it flies with real momentum.
- use caseThrow a window and let physics carry it across the screenDragging a window all the way across a big display is tedious. flingdows lets you flick it: release with speed and the window glides with inertia, slows down, and springs back from the edges.
- how toHow to fling windows on a Mac with flingdowsFlinging a window on macOS takes three things: install flingdows, grant Accessibility access, and release a drag with speed. Here's the full setup, plus how to tune the feel.
- how toTune the fling: strength, friction, edge stiffness, and elasticityflingdows exposes four live sliders that control how your windows move. Here's what fling strength, friction, edge stiffness, and elasticity each do, and how to dial in the feel you want.
- use caseWhy an open-source window manager matters on macOSA window manager needs deep access to your Mac. flingdows is open source under MIT, so you can read exactly what it does, build it yourself, and fork it. Here's why that's the right model for this kind of tool.
