The mess
Related windows drift apart
Mission Control helps you glance. It doesn’t keep the windows you always use together as one unit. You end up hunting, resizing, and rebuilding the same layout every session.
Native macOS utility
Turn the windows you use together into one clean desktop slot.
Stacker Pro stacks windows from any regular Mac app into saved multi-app stacks you can reopen, restore at launch, and switch through without the clutter.
Prefer browser-only stacking? Get free open-source Stacker (MIT · separate app).
Why stack?
Your work isn’t one window. Your desktop shouldn’t pretend it is.
Design tools, docs, browsers, terminals — the same handful of windows keep ending up scattered across spaces. Stacker Pro keeps that set together.
The fix
One stack. One slot. Ready when you are.
Group the windows that belong together into a stack. Switch inside it. Save custom multi-app stacks. Reopen them later — or restore at launch — without redoing your desk from scratch.
How it works
Three short steps to a calmer desktop
Built for people who already know which windows belong together — Stacker Pro just makes that official.
-
Pick the windows
Grab windows from any regular Mac app — not just the browser — and put them in a stack.
-
Save the set
Turn it into a custom multi-app stack you can reopen, deep-link, or restore when Stacker Pro launches.
-
Switch inside the stack
Use the attached switcher with placement, palettes, and jump shortcuts — without scattering your desktop.
Stacker Pro
Concrete power, not fluff
Everything below is part of the full product. No invented extras — just what Pro actually ships.
Any regular Mac app
Stack windows beyond the browser — design tools, editors, docs, terminals, and the rest of your everyday apps.
Multi-app & custom stacks
Build stacks across apps, save them, and reopen the exact set when you need that workspace again.
Restore at launch
Come back to your stacks when Stacker Pro starts — less rebuilding, more picking up where you left off.
Attached switcher
Switch inside a stack with placement options, palettes, and jump shortcuts tuned for speed.
Deep links
Open stacks via stacker-pro:// links — handy for workflows, docs, and muscle-memory shortcuts.
Dock, menu bar & Stack Studio
Add to Dock for quick access, keep controls in the menu bar, and manage stacks in Stack Studio.

Requirements & trust
Built like a serious Mac utility
Clear system needs, honest distribution notes — no App Store theater.
macOS 15+
Stacker Pro targets current macOS. You’ll need Sequoia or newer to run it.
Accessibility permission
Window stacking needs Accessibility access so Stacker Pro can work with app windows the way a power-user utility should.
Signed & notarized
Direct Developer ID signed and notarized DMG — not the Mac App Store. In-app updates use Sparkle from this same site.
What Stacker Pro does not promise
It is a third-party window utility, not a system window manager. macOS Accessibility does not expose every window the same way, and Stage Manager, fullscreen Spaces, and sleep/wake can pause or detach a stack. Reliability follows each app. See Help for the honest limits.
