A macOS window switcher with live previews
By Igor C. · June 2, 2026 · 2 min read
If you have ever held Cmd+Tab on a Mac with two terminals, three browser windows, and a couple of documents open, you know the problem. The switcher shows one icon per app. You release the keys, land on the wrong window, and tab around again. There is no preview of what you are actually switching to.
That single missing thing, a preview, is most of why window switching on macOS feels worse than it should.
What "with previews" actually buys you
A window switcher with live previews shows the real content of each window as you move through the list, not just an app icon. The difference sounds small until you use it:
- Two windows of the same app stop being a guessing game. Three Chrome windows look identical as icons. As previews, you instantly see which one has your docs and which has your email.
- You stop overshooting. Because you can see the target before you commit, you release on the right window the first time.
- Your eyes do the work, not your memory. No more building a mental map of "the third terminal is the one running the server."
How Scopo does it
Scopo replaces Cmd+Tab with a macOS window switcher that lists individual windows instead of apps, each with a live preview. As you tap Tab to cycle, you see the actual window content update in real time.
The part that makes it calm rather than overwhelming: previews are scoped to your current Space. You do not see live thumbnails of every window on your machine, only the ones for the project you are in right now. One Space, one project, one short list of previews.
If you want larger thumbnails as you navigate, the Preview Deck gives you a bigger view of each window before you switch.
Try it
A window switcher with previews is one of those things that is hard to give up once you have it. You can try Scopo free for 30 days, no credit card required, and see whether guessing-free switching sticks for you too.
