Looking for an AltTab alternative on Mac? A leaner window switcher
If you've gone looking for a better way to switch windows on macOS, you've met AltTab. It's the default recommendation in every thread, and for good reason: it's free, open source, mature, and it brings the Windows-style Alt-Tab — a grid of live thumbnails — to the Mac. So why would anyone want an AltTab alternative? Usually because the thing that makes AltTab great for some people is the thing that makes it too much for others. This is an honest look at where AltTab shines, where a leaner switcher fits better, and how Let's Switch compares.
First, give AltTab its due
AltTab is genuinely excellent, and if it already works for you there's little reason to change. It shows live thumbnail previews of every window, adapts the thumbnail size to how many windows you have open, supports type-to-search, has trackpad gestures and dark mode, and is deeply configurable — you can tune almost everything. As of 2026 it also added an optional AltTab Pro (a one-time purchase, around $9.99, while the core app stays free and open source) that unlocks extra appearance styles, instant search, and up to nine independent shortcut sets with per-shortcut filters.
That depth is the whole point. AltTab is for people who want a powerful, tweakable, thumbnail-first switcher and are happy to spend a few minutes in its preferences. The case for an alternative isn't that AltTab is bad — it's that not everyone wants that.
When you'd want an AltTab alternative
A few reasons people go looking:
- You don't want a preferences deep-dive. AltTab's power comes from a long settings screen. If you'd rather install something that works out of the box, with little to tune, that depth is more than you need.
- You want most-recently-used order to be the whole story. Much of window switching is "take me back to the window I just left." A switcher built around a flat, newest-first list makes that a single tap, with nothing else to look at.
- You want it to disappear when you're not using it. A menu-bar utility with no Dock icon and no window of its own stays out of the way between presses.
- You like the idea of one tool that also handles same-app windows and launching. Rather than configuring multiple shortcut sets, you press one key for recent windows, one for the current app's windows, and one search box that finds open windows and launches apps.
If none of those describe you, AltTab is probably the right tool and you can stop here. If a couple of them landed, read on.
How Let's Switch approaches it
Let's Switch is built around a smaller idea than AltTab: get you to the right window in as few keystrokes as possible, then get out of the way. Hold ⌥ and tap ⇥ (Option-Tab) to flip through your windows in most-recently-used order — across apps and monitors — newest first, so the window you just came from is one tap away. The overlay is a compact bar of live window previews, laid out in that most-recently-used order rather than AltTab's adaptive grid. Release Option and you're there. (AltTab happens to use the same Option-Tab default, so the muscle memory carries straight over.)
Two more moves round it out. Hold ⌥ and tap ` (Option-backtick) to cycle just the current app's windows, with every other app kept out of the overlay — the scoped version of Option-Tab. Both of those are in the free tier. The Pro tier adds an ⌥ Space search palette: start typing to fuzzy-find any open window and press Return to jump there — and press ⌥ Space again and the same box switches to launching any installed app, even one that isn't open yet. So the one shortcut you reach for to find a window also launches apps.
Let's Switch is a quiet menu-bar app with no Dock icon. Pro is a one-time purchase with a license key good for up to 20 devices — no account, no subscription, and no telemetry or tracking. One honest caveat: it does not switch across Spaces (virtual desktops), so if your workflow leans heavily on multiple Spaces, factor that in.
AltTab vs. Let's Switch, side by side
| AltTab | Let's Switch | |
|---|---|---|
| Default trigger | Option-Tab (⌥⇥) | Option-Tab (⌥⇥) |
| Overlay style | Adaptive grid of live thumbnails | Compact bar of live previews, most-recently-used order |
| Cycle one app's windows | Yes (configurable) | Yes (⌥ `), free |
| Reaches windows across monitors | Yes | Yes |
| Search to a window by name | Yes (type to filter; instant search in Pro) | Yes (⌥ Space, Pro) |
| Also launches apps | No | Yes (⌥ Space, Pro) |
| Configurability | Very deep | Deliberately minimal |
| Open source | Yes | No |
| Switches across Spaces | Yes | No |
| Price | Free & open source; Pro ~$9.99 one-time | Free tier; Pro pay-once |
The honest read: AltTab wins on being open source, on raw configurability, and on reaching across Spaces. Let's Switch wins if you want a minimal MRU-first switcher that stays out of the way, free same-app cycling, and a single search palette that doubles as an app launcher. Both are pay-once if you upgrade — neither charges a subscription.
A note on the bigger picture
Switching is only half of a keyboard-first window workflow. The other half is putting windows where you want them, which is what a tiler like Let's Tile handles — summon a visible grid and snap a window into place in a few keystrokes. Place windows with one, reach the right one with the other, and you've got a mouse-free way around your Mac. There's more on that over on the blog.
Frequently asked questions
Is there a paid alternative to AltTab? Yes. Let's Switch is a commercial window switcher with a free tier and a one-time Pro upgrade (no subscription, no account). It takes a leaner, most-recently-used approach with far less to configure than AltTab. AltTab itself is free and open source, with an optional one-time Pro tier added in 2026.
Is AltTab still free? The core AltTab app remains free and open source. In 2026 it introduced an optional AltTab Pro (a one-time purchase) for extra appearance styles, instant search, and more shortcut options, while keeping the base app free.
What's the difference between AltTab and Let's Switch? Both show live window previews. AltTab lays them out in an adaptive grid and is highly configurable; Let's Switch shows a compact overlay in most-recently-used order and is deliberately minimal to set up. Let's Switch's Pro search palette also launches apps, but it doesn't switch across Spaces, which AltTab can.
Do I have to pay for either one? No. AltTab's core app is free; Let's Switch has a free tier that covers Option-Tab window switching and Option-backtick same-app cycling. You only pay if you want each app's Pro extras, and both are one-time purchases.
