Private alpha · Windows tiling window manager
Instant, keyboard-driven layouts for the apps you already use. Window motion engineered not to flicker, one input grammar for every surface, and recovery safeguards that hand your desktop back the way GxMux found it.

The feel
Most tilers repaint windows they never needed to touch — that’s the white flash you see on every workspace switch. GxMux treats a stray repaint as a bug, and the whole placement pipeline is built around that rule.
It’s enforced in code, not in copy: the engine ships with a dedicated blink-invariant regression test, and any reported flicker is handled as a defect, not a quirk.
The daily loop
Real captures where they exist, concept boards where they don’t — every clip is labeled with what it is.
Everything from the home row
Focus, move, split, resize, and jump workspaces from one modifier and the home row — RCtrl by default, remappable to Caps Lock and others. A command palette with 142 searchable commands and a fully editable keymap mean you memorize exactly as much as you want to.

The one you’ll show people
Peek fuzzy-searches every window and summons the one you pick as a live floating overlay on the monitor you’re working on — usable in place — while the layout underneath stays untouched. Esc returns it to its home tile, and a pinned tab remembers the windows you reach for.
RCtrl+P peek
A desktop with an address bar
Every window has an address, and the breadcrumb navigator walks it as segments — arrow across, preview candidates live, Enter to jump. Complex multi-monitor setups stop being a memory game.
RCtrl+Space navigate
See everything at once
The app grid lays every window out as live preview cards over your wallpaper. Press an app’s first letter to jump when it’s unique; when several apps share it, the grid narrows until one more keystroke lands you there.
RCtrl+Shift+A app grid
Your setup, saved
The whole arrangement — every monitor, workspace, and stack — is snapshotted by app identity and rebuilt on the next launch. Named layout slots hold whole working modes, saved workspaces can relaunch their apps, and docking your laptop switches to the matching layout profile automatically.
RCtrl+Alt+1–9 layout slots
Mouse when you want it
Hold RCtrl and every pane grows quiet live handles — window thumbnails you drag onto another pane to stack, swap, or re-place, and divider grips for resizing. Let go of the key and the layer is gone.

The grammar
Every palette obeys the same rule — the window switcher, the command palette, the layout picker, even the Alt+Tab takeover. Hold the modifier, type to narrow, release to commit. Learn it once and you know the whole app.
Fluent hold · no capture yet
No shortcuts required
Arrange mode (RCtrl+E) turns every tile into a card: drag to swap or stack, pull windows onto workspace chips, resize through the gaps, then confirm. A gentle on-ramp if shortcuts aren’t your thing.

The operating rule
That sentence is the actual design rule the recovery layer is built around. Here’s what it means in practice — and where the honest limits are.
GxMux.exe --safe boots paused: no layout restore, no styling, nothing touched until you resume from the tray.Where the money goes
Free Windows tilers are genuinely capable — if one already fits you, keep it. This table describes focus, not benchmarks; the right-hand column varies by tool and by how much configuration you enjoy.
| Capability | GxMux | Typical free-tiler setup |
|---|---|---|
| Repaint-conscious window motion, guarded by regression tests | Built in | Varies by tool |
| One hold-type-release grammar across every palette | Built in | Usually per-feature bindings |
| Summon a window in place without changing the layout (Peek) | Built in | Uncommon |
| Restore-on-exit, crash journal, safe mode | Built in | Varies; often manual |
| Mouse escape hatches (Arrange mode, modkey layer) | Built in | Varies by tool |
| Whole-desktop save; saved workspaces can relaunch apps | Built in | Often DIY scripting |
| GUI settings with an editable, conflict-checked keymap | Built in | Often text config |

Objections, answered
Most normal desktop windows tile fine. Elevated (admin) windows can’t be moved unless GxMux itself runs elevated — you get a one-time notice instead of silent failure. Tool windows and self-sizing popups are deliberately left alone, and per-app rules let you float or ignore anything that shouldn’t be managed.
Original window placements and title-bar styles are journaled before GxMux touches anything. If windows are stranded off-screen by a forced kill, a watchdog puts them back within seconds — even before a relaunch. The next launch replays the recovery journal, and a safe mode (GxMux.exe --safe) starts paused without touching your layout at all.
No. Arrange mode is a drag-and-drop editor for the whole layout, holding the modifier reveals a mouse layer with draggable window thumbnails and resize grips, and the command palette makes every command searchable. Shortcuts make GxMux fast, but they’re not the price of admission.
Each monitor has its own workspaces, windows move across monitors with one shortcut, and positioning is done in physical pixels so mixed-DPI setups land windows accurately. Layout profiles are saved per monitor arrangement — docking or undocking a laptop switches to the matching profile automatically.
Those are good free tools, and if one already fits you, keep it. GxMux concentrates on the parts around tiling: window motion engineered not to flicker, one hold-type-release grammar across every surface, mouse escape hatches, and a recovery model that restores your desktop after crashes and on exit. It’s a different set of trade-offs, not a claim that the free tools don’t work.
The intent is a one-time license, not a subscription — but the final price and licensing terms aren’t settled, and there’s no checkout yet. Early access is free and takes no payment.
GxMux uploads no telemetry or usage data. Window titles appear only in the local log and saved layouts on your disk, and crash dumps stay local unless you choose to share them. The app’s only routine network request is a GitHub Releases update check.
Not publicly yet. GxMux is in private alpha: there’s no public installer, and the build isn’t code-signed yet — we won’t ship a global-hook app that trips SmartScreen warnings. Email us for early access; it’s free and no payment is taken.
Private alpha
GxMux is being hardened for public release — code signing, the install matrix, and pricing are still in flight. Early-access users run the packaged alpha, talk directly to the developer, and shape what 1.0 ships.
Free while in private alpha. No payment is taken, and requesting access is not a purchase.
