Gridly lives in your menu bar and tiles any window into halves, quarters, thirds, a 3×3 grid — or an even N-way split — with a single keystroke.

Why Gridly
No dragging to screen edges, no fiddly resize handles. Focus a window, press a shortcut, done.
Every layout is a chord away. ⌃⌥ plus an arrow, letter, or number — muscle-memory in a day.
Press ⌃⌥⇧ and a number to split the screen into that many equal tiles and fill them with your frontmost windows.
The classics: left/right/top/bottom halves and four corners, exactly where you expect them.
Columns, two-thirds spans, and nine grid cells laid out like a numeric keypad.
Fling the focused window to the next or previous screen with ⌃⌥⇧ and an arrow key.
A tiny native menu-bar app — no dock icon, no background bloat, no telemetry. Launches at login if you like.
Cheat sheet
A few of the layouts. The full reference lives in Gridly’s Preferences window.
Get going
Gridly is a single app with one permission to grant.
Open the .dmg and drag Gridly into your Applications folder. Launch it — it appears in the menu bar.
macOS asks once. Allow Gridly under System Settings ▸ Privacy & Security ▸ Accessibility so it can move windows.
Click a window to focus it, then press a shortcut. Open Preferences from the menu-bar icon for the full list.
Questions
Press ⌃⌥⇧ together with a number from 1–9. Gridly carves the screen into that many equal tiles — the most square arrangement it can — and drops your frontmost windows into them. ⌃⌥⇧2 gives side-by-side halves, ⌃⌥⇧4 a 2×2 grid, ⌃⌥⇧9 a full 3×3. If you have fewer windows open than the number you pressed, the grid shrinks to fit so there are never empty gaps.
Any Mac running macOS 14 (Sonoma) or later, on both Apple Silicon and Intel.
Moving and resizing other apps’ windows is only possible through macOS’s Accessibility API. Gridly requests nothing else — no network, no files, no analytics.
The current build ships with a fixed set of keyboard bindings (shown in Preferences). Customisable shortcuts are on the roadmap.
No — the Accessibility API is incompatible with App Store sandboxing, so Gridly is distributed as a notarized direct download.
Free, notarized, and about two megabytes. Your windows will thank you.
Gridly is free — if it saves you time, a coffee is always appreciated. Replace the download link with your DMG and the coffee link with your Buy Me a Coffee handle.
