KeyFreezer
Lock your Mac keyboard, instantly.
Block every keystroke system-wide with ⌘ ⇧ F. Cursor completions, builds, and terminal sessions keep running. Optional on-screen feedback confirms every blocked key, so you always know the lock is active.

What it does
A reliable keyboard-off switch
that lives in your menu bar.
KeyFreezer blocks every keystroke across every macOS app with one shortcut, and unblocks with the same one. No lost work, no stray shortcuts, no curious hands interfering.
No Dock icon. No account. No cloud. Just a tray icon, the macOS Accessibility permission, and a shortcut you choose.
Sound familiar?
- AI coding sessions where one stray key interrupts Cursor mid-generation or breaks a long-running shell.
- Children walking up to an open Mac the moment you step away from the desk.
- Pets crossing the keyboard while you are not looking, firing shortcuts into every open window.
- Cleaning keys or wiping the screen without typing into every open app.
- Screenshares and demos where a single stray letter would derail the flow.
Features
Built for the moment you need
the keyboard to stop.
Every behavior on this page ships in the app today.
Protect Cursor and terminals
Let AI completions finish and builds run undisturbed. A stray keypress never interrupts a generation or kills a long-running process again.
Safe for curious hands
Children or pets can press every key they want. Each triggers a visual effect instead of modifying files, firing shortcuts, or closing apps.
System-wide freeze
Keyboard input is blocked across every macOS app the moment you toggle. Apps stay open, your work is untouched, mouse stays free.
One shortcut, any app
⌘ ⇧ F by default. Toggle freeze from anywhere (fullscreen, calls, presentations) and reassign it once from the menu bar popover.
How it works
Four steps. One locked keyboard.
Install KeyFreezer
Drag the signed .app into your Applications folder and open it once. KeyFreezer hides the Dock icon and lives entirely in the menu bar.
Grant Accessibility
macOS asks for Accessibility access the first time you toggle freeze. This permission is what lets KeyFreezer intercept keys system-wide.
Set your shortcut
The default is ⌘ ⇧ F. Open the popover from the tray to assign any combination that fits your workflow.
Freeze from any app
Press the shortcut to lock the keyboard. Press it again to unlock, even mid-fullscreen, mid-call, or mid-presentation.

Permissions & privacy
A tool you control, not a service.
KeyFreezer needs the macOS Accessibility permission to intercept keys. That is the only privilege it requests, and you can revoke it at any time from System Settings.
No cloud, no telemetry
Runs entirely on your Mac. No account, no internet connection required. Your shortcut and settings are stored locally and never leave the machine.
Keys are dropped, not logged
While frozen, presses are intercepted at the system level and discarded. They are not forwarded to apps and are never stored anywhere.
