Keyboard-First Tiling · 100% On-Device
Your windows,
exactly where you want them.
Press CtrlAlt← and the focused window takes the left half. Press it again and it steps to two-thirds, then a third: no second shortcut to memorize. Drag toward an edge instead and a translucent preview names the tile before you let go. Save where every window sits, and the layout comes back on its own the moment you dock or undock, matched to that exact set of monitors.

How it works
Install. Press Ctrl+Alt+←.
Install: no admin needed
Run the installer and Snapr lands in your own user folder, no UAC prompt. It lives in the notification area: there's no window at all until you open Settings.
Use the shortcuts you already know
Defaults are CtrlAlt plus a key (Rectangle's keymap, same as the Mac build), so there's nothing to relearn. CtrlAlt/ any time for the full cheat sheet.
Or drag to an edge
A translucent preview names the tile as you drag. Release to snap. The bottom edge is a thirds ruler: left third, left two-thirds, center third, right two-thirds, right third, which Windows' own edge snapping doesn't offer.
Save the layout once
Arrange your windows the way you like them and save it. From then on, docking or undocking that exact set of displays restores the arrangement automatically, a couple of seconds later.
Features
Fifty-five commands. One cheat sheet.
Rectangle's keymap, so your muscle memory carries over, plus the layout, multi-display and drag-to-snap work that Windows' own tiling stops short of.
Cycle on repeat
Press the same direction again and again and a window steps ½ → ⅔ → ⅓ instead of sitting at a fixed half. The cycle is per-window and expires after 1.5 seconds, so snapping one window and then pressing the same key on another starts that one from a half.
No second shortcut
Drag to an edge, see the name
A translucent preview shows exactly where the window will land, gaps included, with the tile's name written across it, because a colored rectangle alone is genuinely ambiguous between "Left Two-Thirds" and "Center Third" on an ultrawide. The bottom edge is a thirds ruler Windows has no equivalent for.
Named preview
Layouts that know your desk
Save an arrangement of every window and put it back with one command, or let Snapr do it automatically 2.5 seconds after you dock or undock. Each layout remembers the exact set of monitors it was saved on by hardware identity, not just resolution, and stores positions as proportions so a 4K layout restores correctly on a laptop panel.
Dock / undock
It refuses to guess
If two saved layouts match the same set of displays, Snapr restores neither and says so in Settings, rather than rearranging twenty windows the wrong way. Doing nothing is recoverable; guessing wrong twenty times over isn't.
Honest by default
Real multi-display commands
Move to the next or previous display, to the one physically left, right, up or down, or straight to display 1-4, keeping the window's relative place and size.
Up to 4 displays
Tile All
Arranges the windows on the monitor under your pointer into a grid that stays close to square, scoped to one display on purpose, so a command you ran for your laptop screen never rearranges a second monitor you weren't even looking at.
One display, on purpose
Every shortcut is yours
All 55 commands are rebindable, with live conflict detection: Snapr names a binding it can't take as "In use by another app" rather than leaving you pressing a dead key. CtrlAlt/ puts the whole cheat sheet on screen over whatever you're working in.
55 commands
It won't fight Windows for its own shortcuts
Win+arrow belongs to Windows Snap, and Snapr refuses to take it, along with Win+Tab, Alt+Tab, Ctrl+Alt+Del and the rest of the shell's own bindings. Snapr runs alongside Windows Snap, Snap Layouts and PowerToys FancyZones. It doesn't disable or replace any of them.
Plays well with Windows
It tells you when it can't
No eligible window, an ignored app, a minimized window, a window that refuses to resize, "there's only one display", "nothing to undo". An app running as administrator is named specifically, since Windows won't let an ordinary process move its windows. Each produces a short sentence instead of a shortcut that looks broken.
Never silent
Pixel-correct on any display
Windows placed by the true visible frame (not the invisible resize border every window carries), per-monitor DPI awareness taken before the first window exists, and every tile computed against the real work area, so a taskbar on any edge, auto-hidden or not, needs no workaround. No gaps, no overlap, even at 200% scaling or a mixed-DPI desk.
Engineered for Win32
Gaps, steps, and an ignore list
Configurable gaps between tiled windows with a live preview, adjustable nudge and resize steps, settings import/export for a second PC, launch at login, and an app ignore list for VMs, games and remote-desktop sessions, the three things a window manager reliably breaks.

No admin, no usage analytics
Per-user install, no UAC prompt, no kernel driver, no shell extension, no low-level input hook. Drag detection is a passive, out-of-context hook that cannot block or slow another app's drag. No account, no usage analytics. Updates check silently about once a week and install themselves after verifying the signature and version.

History
Beta
You're testing the first Windows build.
Snapr has been on the Mac for a while. This is the Windows port's first public build: the same 55 commands and the same guarantees, rebuilt on Win32 APIs it needed to get right (DPI awareness, frame borders, elevated apps, taskbar edges) rather than macOS ones. It passes its own 490-test suite.
What would help most
Multiple displays, for real
Development so far has run on one physical display. The multi-monitor, dock/undock and mixed-DPI paths are covered by simulated-monitor tests, not real hardware yet. If you dock, undock, or run a mixed-DPI desk, that's the single most valuable thing you could try.
Drag-to-snap, from real work
From a maximized browser, from a second monitor, fast drags and slow ones. Does the preview always name the tile you expect?
Your actual shortcut habits
Rebind things, create a conflict on purpose, and if you're on a non-US keyboard layout, try a Ctrl+Alt shortcut and see whether the AltGr warning catches it.
The install itself
Whether SmartScreen let you through, whether the taskbar icon and Start Menu entry look right, whether uninstall leaves anything behind.
Pricing
Free for you. Fair for work.

Everything Snapr needs is inside the installer: no Python, no runtime to chase down. Its settings window does use the Microsoft Edge WebView2 Runtime to draw its interface, which ships with Windows 11 and reaches almost every Windows 10 machine through Windows Update. On the rare PC without it, Snapr will say so on first launch of Settings, and Microsoft's free installer is a one-click fix. The tray icon and every hotkey work either way.
No admin rights needed
Snapr installs per-user into
%LOCALAPPDATA%\Programs\Snapr, so there's no UAC prompt and no argument with your IT department. Uninstall from Settings → Apps → Installed apps like anything else.Windows may warn you the first time. Here's the honest story.
Snapr is Authenticode-signed, so the publisher shows as a real, verified name rather than "Unknown publisher." But signing alone does not switch SmartScreen off: Microsoft builds reputation per file, and a brand-new build starts with none. Until this exact file has been downloaded enough times, you may still see a blue "Windows protected your PC" box.

FAQ
Common questions.
Is Snapr really free?
Personal use is free forever: all 55 commands, every layout feature, no key, no account, no trial timer, no nag screens. If you use Snapr at work, a one-time $5 business license per computer keeps it supported.
How is this different from Windows' own Snap Layouts, or PowerToys FancyZones?
Windows already snaps windows and is good at it: drag to an edge or press Win+arrow for halves and quarters, hover the maximize button (or Win+Z) for Snap Layouts, or install PowerToys FancyZones for a hand-drawn zone grid. Snapr neither replaces nor disables any of them: it deliberately refuses to bind their shortcuts, and it installs no shell extension, driver or low-level input hook that could get in their way. Run all of them side by side and nothing collides. What Snapr adds: cycling through sizes on repeat instead of one fixed half; thirds, sixths and fourths, not just halves and quarters; layouts that save an entire desk and auto-restore by monitor identity when you dock or undock; per-display moves that keep a window's relative place and size; and undo/redo for window positions. If Snap Layouts already does what you need, use Snap Layouts. Snapr is for people who want the whole thing on the keyboard, and who move between a laptop and a desk.
What sizes can it snap to?
Halves, thirds, two-thirds, quarters, fourths, three-fourths and sixths. Press the same direction again and it cycles: CtrlAlt← steps ½ → ⅔ → ⅓. There's also Maximize, Maximize Height, Maximize Width, Almost Maximize, Center, Larger/Smaller, nudge in any direction, and undo/redo/restore for window changes.
Does it work with multiple displays?
Yes. Move a window to the next or previous display, to the one physically left, right, up or down, or straight to display 1-4, keeping its relative position and size. Layouts are stored as proportions rather than pixels, so an arrangement captured on a 4K monitor restores correctly onto a laptop screen.
What happens when I dock or undock?
If you've saved a layout for that exact set of displays, Snapr restores it about 2.5 seconds after the change settles, long enough for Windows to finish rearranging things itself first. Each layout is matched by monitor hardware identity, not just resolution, because two identical 1080p panels at home and at the office would otherwise be indistinguishable. If two saved layouts match the same desk, Snapr restores neither and tells you in Settings, rather than guessing wrong.
Does drag-to-snap get in the way of normal dragging?
It only arms once a window is genuinely being moved, so clicks and text selections never trigger it. Detection is a passive, out-of-context hook that polls the cursor only for the length of an actual drag. It cannot block or slow down anything else on the machine.
Can I change the shortcuts?
All 55 of them, to any combination, with live conflict detection: Snapr names a binding as "In use by another app" if something else got there first. Some shortcuts it will never let you take: Win+arrow, Win+Tab, Alt+Tab, Ctrl+Alt+Del and a handful of others Windows itself reserves. The editor refuses these with a reason instead of accepting a binding the OS will never deliver. On non-US keyboard layouts, Snapr also flags any binding that collides with AltGr.
What about Windows virtual desktops?
Windows marks a window on another virtual desktop as "cloaked" while it still technically reports itself as visible. Snapr checks for that specifically, so a Tile All or a shortcut never reaches out and rearranges a window on a desktop you aren't looking at.
What if a window won't move?
You get a short, specific reason: no eligible window, an ignored app, a minimized window, or a window that refuses to resize. An app running as administrator is named specifically: Windows won't let an ordinary process reposition an elevated one, and Snapr deliberately never runs elevated itself, so it reports the refusal rather than fumbling it. A shortcut that silently does nothing is indistinguishable from a broken app.
Does Snapr need any special permission, like macOS's Accessibility access?
No. Windows lets an ordinary, non-elevated app reposition another app's windows through the standard Win32 APIs, so there's no permission dialog to grant and no setting to find. Install it and the shortcuts work immediately. The one thing Windows won't allow, by design, is moving a window that belongs to an elevated (administrator) process, which Snapr detects and reports rather than failing silently.
Can I stop it touching certain apps?
Yes. There's an ignore list for VMs, games and remote-desktop sessions, the three things a window manager reliably breaks. A tray-menu item also lets you ignore whatever app is currently frontmost in one click.
Why did Windows show a blue "protected your PC" warning?
Because the file is new, not because it's unsigned. SmartScreen builds trust per file over downloads and time, and a fresh build starts from zero. Code signing gives you a verified publisher name in the dialog but does not skip it. Click More info → check the publisher → Run anyway. See the install section for the full explanation.
How do I update Snapr?
It updates itself. Snapr quietly checks about once a week and lets you know when there's something new, never a pop-up, and you can turn the check off. Choosing to update downloads the new installer, verifies its signature and version before running anything, installs over itself and reopens. If any of those checks fail it deletes the download and sends you here instead. Your settings and layouts carry over.
Where do my settings live, and what does uninstalling remove?
Preferences sit in
%APPDATA%\Snapr\prefs.json and saved layouts in %APPDATA%\Snapr\layouts.json, both written atomically, so a layouts file that gets corrupted is moved aside rather than silently overwritten. Uninstalling removes the app from %LOCALAPPDATA%\Programs\Snapr and the launch-at-login entry; delete the two files above as well if you want every trace gone.
