A scrolling window manager for macOS
Windows in a row,
not a pile.
slideNudge lines up every window side by side and slides the row across your screen. New windows join next to the one you're in, nothing gets squeezed, and the window you're working in stays in the middle.
Try it: click the strip, then use the arrow keys
How it works
Tiling that doesn't fight you.
-
Nothing gets squeezed
Most tilers split the screen again every time a window opens, until everything is a sliver. Here a new window just joins the row at its own width.
-
See what's next
The window you're in stays in the middle, and its neighbours hang off both edges of the screen. Click one and the row slides over to it.
-
Keyboard first
Focus, move and resize windows without reaching for the mouse. Every shortcut can be changed in Settings.
-
A map when you switch
Each shortcut pops up a small map of the row at the bottom of the screen for a moment, so you always know where you are.
-
Drag to rearrange
Drop a window between two others and it takes that spot. Drag its edge and the row remembers the new width.
-
A row per display
Each screen gets its own row. Drag a window onto another display and it joins that row instead.
-
Plays well with macOS
Spaces, full-screen apps, Cmd-Tab and minimised windows all work as usual. No need to switch off System Integrity Protection.
-
Leave some apps out
Calculators, music players, chat windows: pick the apps that float on their own, or float any one window with a shortcut.
The keys
Hold ⌃⌥ and steer.
Control and Option together are a combination few apps claim. Change any of these in Settings.

macOS asks before any app can move other apps' windows. Turn on slideNudge in Privacy & Security → Accessibility.
FAQ
Fair questions.
Is it really free?
Yes. No trial, no account, no license key.
Which Macs does it run on?
Any Mac with macOS 14 Sonoma or later, Apple silicon or Intel. It’s one universal app, an 800 KB download.
Is it safe to open?
Yes. slideNudge is signed with a Developer ID and notarized by Apple, so macOS checks it before it opens. The first time, macOS asks whether you want to open an app you downloaded: click Open.
Why does it need Accessibility access?
That's the permission macOS uses for anything that moves or resizes other apps' windows. slideNudge reads where windows are and what they're called, moves them, and that's it. Nothing leaves your Mac: the app never connects to the internet. More in the privacy policy.
What happens to the windows I already have open?
They join the row in the order they sit on screen. Big ones shrink to half the screen so you see a few at once; smaller ones keep their size. Quit slideNudge and every window comes back on screen.
Do I have to disable System Integrity Protection?
No. slideNudge only uses the regular Accessibility permission.
What happens to Spaces and full-screen apps?
Each Space keeps its own windows in order. Full-screen windows and minimised windows step out of the row and rejoin when they come back.
What if I quit it or switch it off?
Every window that was tucked off screen comes back into view, so nothing gets lost.
How do I uninstall it?
Quit it from the menu bar and drag it from Applications to the Bin. You can also remove it from the Accessibility list in System Settings.
