Windows 11’s Alt+Tab still shows a flat strip of thumbnails, in a fixed grid, with no way to pin the four windows you actually live in. Stardock’s new AltTabby fixes that with pinning, grouping, custom layouts, and a Windows key + Tab hijack. It is a $9.99 fix ($7.99 in beta) for a problem Microsoft has ignored for a decade, and it deserves the attention it is getting.
But it is not the only option. If you want AltTabby alternatives that go further on tiling, cost nothing, or stack a dozen other window tools on top, the Windows power-user scene has quietly built a bench that is deeper than most people realise. We ran through the credible candidates for a week each and picked seven worth your time.

Why people want more than Windows 11 Alt+Tab
The complaint on Windows forums is consistent. Alt+Tab in Windows 11 is a memory carousel, not a workspace tool. Users on Reddit’s r/Windows11 keep flagging the same friction:
The layout is fixed and stale
You get thumbnails in a single grid. No columns you can rearrange, no groups, no way to keep your four main windows anchored while the noise scrolls past. This is what AltTabby’s custom layouts, carousel, and grid modes are answering.
Nothing stays where you put it
Open a fifth window and your visual muscle memory breaks. Pinning is not a real feature in the built-in switcher, so the Alt+Tab order shifts under you every session.
Apps do not group
Six Chrome windows, four VS Code projects, three Slack workspaces. Windows 11 lists them all as flat siblings. There is no per-app collapse and no per-project bucket. AltTabby’s intelligent grouping is a direct fix, and it is one of the strongest arguments for paying $9.99.
Win+Tab and Alt+Tab do different things
Win+Tab opens Task View with virtual desktops. Alt+Tab does the thumbnail strip. Users repeatedly ask why they cannot just have one switcher for both. AltTabby lets you reassign Win+Tab to itself, which is a small thing that many buyers cite as the deciding feature.
Power-user shortcuts are shallow
There is no filter-as-you-type, no keyboard-only navigation across multiple monitors, no rebindable secondary shortcuts. Everything past Alt+Tab and Alt+Shift+Tab is missing, which is why search-driven switchers like Alt-Tab Terminator still have an audience.
The seven picks below each answer a subset of those complaints. Read the ones that match yours, skip the rest.
The alternatives
PowerToys FancyZones – Best free tiling companion
PowerToys FancyZones is Microsoft’s own answer to Windows 11 window management, shipped as a module inside the free PowerToys utility. It does not replace Alt+Tab, it replaces the snap layout system. You build custom zone grids per monitor (three vertical columns for an ultrawide, a two-plus-one layout for a coding setup, a five-zone canvas for a stream deck) and drop windows into them with a modifier drag. On a 21:9 or 32:9 display, FancyZones is closer to a proper tiling window manager than anything else Microsoft ships.
Where it falls short: It does nothing for switching. If your pain is Alt+Tab, FancyZones will not fix it. You will still need AltTabby, WindowSwitcherW11, or Alt-Tab Terminator on top. Also, it does not remember which zone a window belongs to across reboots for every app, which trips people up.
Pricing:
- Free: Full feature set, no tiers.
- Paid: None.
- vs AltTabby: Complementary, not overlapping. Pair FancyZones with AltTabby and you cover both halves of the problem for $9.99.
Migrating from AltTabby: You are not migrating, you are adding. AltTabby users who spend most of their time inside a set layout should install PowerToys to handle the tiling and keep AltTabby for the switcher. Setup time for a working three-zone layout is roughly ten minutes.
Download: PowerToys on GitHub · Microsoft Store
Bottom line: Install this even if you also buy AltTabby. If you cannot pay for AltTabby, FancyZones is the strongest free ceiling you can hit on Windows 11.
WindowSwitcherW11 – Best free Alt+Tab replacement
WindowSwitcherW11 is a small open-source utility by jewalky that does one thing well. It restores the Windows 10 Alt+Tab switcher on Windows 11, including live previews at a size the new UI shrank down. If your entire complaint about Windows 11 is “the new Alt+Tab is worse than the old one”, this fixes it for free in about thirty seconds. No install wizard, no telemetry, no account.
Where it falls short: It brings back the old switcher, it does not add anything new. There is no pinning, no grouping, no custom layouts. It is a revert, not a redesign. Development is also low-volume, so do not expect frequent updates.
Pricing:
- Free: MIT-licensed on GitHub.
- Paid: None.
- vs AltTabby: Cheaper by $9.99 and enough for users who only want Windows 10’s Alt+Tab back. AltTabby does much more, but you may not need much more.
Migrating from AltTabby: If you tried AltTabby and just want the pre-Windows 11 behaviour without paying, uninstall AltTabby, drop the WindowSwitcherW11 binary in a Startup folder, done in five minutes.
Download: GitHub
Bottom line: Pick this if your only ask is “give me back Windows 10’s Alt+Tab” and you do not want to pay Stardock. Skip it if you actually want pinning or grouping.
Alt-Tab Terminator – Best search-driven switcher
Alt-Tab Terminator by NTWind is the switcher for people who use search as their primary navigation. Hit Alt+Tab and you get a list of every open window with a live preview and a search field at the top. Start typing “slack” and only Slack windows remain. It has been around since long before AltTabby and Groupy shipped, and the free tier is enough for most users. The Pro upgrade adds multi-monitor placement, exclusions, and custom hotkeys.
Where it falls short: The UI still looks like a Windows 7 utility. It works, but it is not going to win any design comparisons against AltTabby’s carousel view. Some users also find it slower to render previews on very high window counts.
Pricing:
- Free: Full basic tier, no ads, no nag screens.
- Paid: $19.95 for a single-PC Pro licence.
- vs AltTabby: Cheaper in the free tier, pricier at Pro. Pro is a stronger fit for multi-monitor setups than AltTabby’s five-device licence.
Migrating from AltTabby: No migration needed, you just swap the shortcut binding. If you build habits around AltTabby’s pin list, note that Terminator does not have pinning, it filters through search instead.
Download: NTWind · SourceForge
Bottom line: Pick this if you switch by typing, not by scanning thumbnails. It is the fastest switcher we tested for anyone with more than fifteen windows open at once.
Groupy 2 – Best for tab-based workflows
Groupy 2 is Stardock’s other window utility, and it answers a different question. Instead of a better Alt+Tab, it gives you browser-style tabs across every app. Drag one File Explorer window onto another and they become tabs in a single window. Do the same with Word documents, VS Code windows, or Excel files. You can save Groupings that launch a set of apps into one tabbed window from a taskbar shortcut. If your workflow is “these five apps always open together for project X”, Groupy 2 collapses that into one window and one tab bar.
Where it falls short: Not every app plays nicely. UWP and some Electron apps refuse to be tabbed. It is also a different mental model, so users who like their windows as windows will not enjoy the workflow shift.
Pricing:
- Free: 30-day trial.
- Paid: $9.99 for up to five PCs, included in Object Desktop at $39.99 for all Stardock apps.
- vs AltTabby: Same price, different problem. If you already own AltTabby, Object Desktop at $39.99 is a fair bundle to consider.
Migrating from AltTabby: Not a replacement, a companion. AltTabby users who spend time in File Explorer or across many Office documents get the biggest lift from adding Groupy.
Bottom line: Buy this if your work is document-heavy and you envy browser tabs. Skip it if your Alt+Tab pain is really a switching problem, not a grouping problem.
AquaSnap – Best for snap-first workflows
AquaSnap by Nurgo Software focuses on the physical layout of windows, not the switcher. Drag a window to a screen edge and it snaps to that half. Drag to a corner and it takes a quarter. Shake a window and it pins to always-on-top. It handles multi-monitor snap with better precision than Windows 11’s built-in Snap, and the magnetic-edge behaviour makes cascading windows feel deliberate instead of accidental.
Where it falls short: Personal use is free, but the free tier explicitly excludes commercial use. If you are running it at work, you owe them a licence. Also, its keyboard shortcut layer is thinner than PowerToys FancyZones.
Pricing:
- Free: Personal, non-commercial use only.
- Paid: $29 for a lifetime single-PC Professional licence.
- vs AltTabby: A one-time payment against AltTabby’s five-device model. Both are one-and-done purchases in practice, but AquaSnap solves a different half of the problem.
Migrating from AltTabby: Add, do not replace. AquaSnap manages placement, AltTabby manages switching, and they do not conflict.
Download: Nurgo Software · PortableApps
Bottom line: Pick this if you spend more time arranging windows than switching between them. Pair it with AltTabby or PowerToys FancyZones for a full layout.
AltAppSwitcher – Best for macOS refugees
AltAppSwitcher by hdlx is an open-source utility that brings the Mac Cmd+Tab experience to Windows. Instead of cycling through every window, it cycles through applications, then a second modifier expands the windows for that app. If you use both a Mac and a Windows machine, or you learned to switch on macOS and never adapted, this is the only utility we found that gets the behaviour right on Windows 11 24H2. It is small, fast, and does not phone home.
Where it falls short: It is a niche pick. If you have never used a Mac and do not miss app-first switching, the Windows model of window-first switching probably works fine for you. Also, no active support channel beyond GitHub issues.
Pricing:
- Free: MIT-licensed on GitHub.
- Paid: None.
- vs AltTabby: Free where AltTabby is $9.99, but only if you specifically want the Mac model. AltTabby’s grouping is closer to app-first switching for users who do not want to leave the Windows convention.
Migrating from AltTabby: Set the same Alt+Tab binding, uninstall AltTabby if you want to commit fully. AltAppSwitcher does not conflict with FancyZones or AquaSnap.
Download: GitHub
Bottom line: Install this if you switch to Windows from a Mac and want Cmd+Tab behaviour back. Everyone else can skip it.
Actual Window Manager – Best all-in-one paid suite
Actual Window Manager is the kitchen-sink option. It bundles multi-monitor tools, virtual desktops on each monitor, a desktop grid for snap-and-drag, a title-bar button pack (Minimize to Tray, Stay on Top, Roll Up, Move to Monitor), a clipboard manager, a Start-menu replacement, and dozens of keyboard shortcuts. If your window-management wish list runs to ten items, this is the cheapest way to get them in one install instead of stacking four utilities.
Where it falls short: The UI feels dated compared with AltTabby, and there is a lot to learn. Users who only want a better Alt+Tab will feel over-served. At around $50 for the full suite, it is also the most expensive pick on this list.
Pricing:
- Free: 60-day trial.
- Paid: Around $50 for a lifetime licence on the full suite. Individual modules are cheaper if you only want one.
- vs AltTabby: Roughly five times the price, but replaces four or five separate tools. Better value if your list is long, worse if it is short.
Migrating from AltTabby: Install alongside during the trial, decide within the 60 days whether the extra features justify the price. Nothing to migrate at the shortcut level.
Download: Actual Tools
Bottom line: Pick this if you want one tool that covers monitors, desktops, snap, title bars, and clipboard. Skip it if you only want a better switcher, AltTabby is a cleaner fit.
How to choose
Pick PowerToys FancyZones if you want the strongest free option and your problem is layout, not switching. It is the first thing to install on any Windows 11 machine.
Pick WindowSwitcherW11 if the single thing you miss is the Windows 10 Alt+Tab. It is free, tiny, and does exactly that.
Pick Alt-Tab Terminator if you switch by typing app names rather than by looking at thumbnails. The free tier is enough for most users. Buy Pro if you run multi-monitor.
Pick Groupy 2 if your workday is document-heavy and you would rather have five File Explorer tabs than five File Explorer windows. It stacks cleanly with AltTabby, at Object Desktop pricing it is essentially free with the bundle.
Pick AquaSnap if you spend more time arranging windows than switching them, and you want a lifetime licence instead of a device-locked one.
Pick AltAppSwitcher if you came from macOS and want Cmd+Tab back. Nothing else on this list does app-first switching properly.
Pick Actual Window Manager if your wish list runs long. It costs the most because it does the most.
Stay on AltTabby if the specific things you want are custom layouts, pinning, and grouping in one paid app from a publisher that will still exist in three years. That combination is what it does best, and no free tool on this list matches it end-to-end.
FAQ
Is there a free AltTabby alternative?
Yes, several. PowerToys FancyZones handles layout and is free from Microsoft. WindowSwitcherW11 handles Alt+Tab and is free on GitHub. Alt-Tab Terminator has a free basic tier that removes nags and covers most single-monitor users. Between those three you can replicate a large fraction of AltTabby’s value at zero cost, at the price of running three utilities instead of one.
Is PowerToys better than AltTabby?
They solve different problems. PowerToys FancyZones is a tiling and snap tool, AltTabby is a switcher. If you only need one, pick the one that matches your actual pain. Most power users end up running both.
What is the cheapest way to get AltTabby and Groupy 2 together?
Stardock’s Object Desktop bundle is $39.99 and includes both AltTabby and Groupy 2 plus roughly a dozen other Stardock utilities. If you would already pay for both individually at $9.99 each, Object Desktop pays for itself the moment you use a third tool from the bundle.
What is the best open-source AltTabby alternative?
PowerToys FancyZones for layout, WindowSwitcherW11 for switching, and AltAppSwitcher for Mac-style app switching. All three are actively maintained, MIT or MIT-style licensed, and free. None of them, on their own, matches AltTabby’s grouping and pinning, but together they cover most of the same ground.
Does AltTabby work on Windows 10?
AltTabby is Windows 11-only. If you are still on Windows 10, Alt-Tab Terminator, AquaSnap, Actual Window Manager, and PowerToys all run on Windows 10 and give you most of the same functionality.
Can I use one licence across multiple PCs?
AltTabby includes support for up to five devices on a single $9.99 licence. Alt-Tab Terminator Pro is single-PC. Groupy 2 is five PCs. AquaSnap Professional is single-PC. Actual Window Manager is single-PC. If you have several machines to cover, AltTabby and Groupy 2 come out ahead per device.
