Your cat is not
a developer.

MeowProof locks your keyboard in one click — and auto-locks when it detects paw-walking. No more jjjjkkkkaaaaaa sent to production, closed documents, or misfired shortcuts.

Features

Everything you need.
Nothing you don't.

A focused utility that does one thing well — with a handful of extras for cat owners who've been burned before.

One-click keyboard lock

Blocks every key system-wide. Hit Lock Keyboard in the window, tray menu, or press Ctrl+Shift+L from anywhere.

Smart cat detection

Watches for paw-like typing in the background. Auto-locks the moment it spots cat chaos — no input needed from you.

Glassmorphism overlay

A full-screen frosted blur appears on every monitor when locked. Or use Stealth Lock for a completely silent, invisible lock.

Sound feedback

Optional sounds on lock and every blocked keystroke. Choose from 7 built-in sounds, or import your own. Great for deterring persistent paws.

Smart sleep behavior

Auto-unlocks on sleep or session lock — so you're never locked out of your own machine. Keeps your display awake while locked, too.

Launch at login

Set it and forget it — MeowProof starts automatically with Windows and repairs itself if you ever move it to a new folder.

How it works

Up and running in
thirty seconds flat.

Download and you're done. No setup, no configuration, no fuss.

01

Download & launch

Download MeowProof and double-click it — that's the whole setup. It starts in your system tray right away.

02

Lock when needed

Click Lock Keyboard in the window or tray, or press Ctrl+Shift+L from any app, any time.

03

Unlock. Your cat cannot.

Press Ctrl+Shift+L — works even while everything else is blocked. Your cat definitely can't do that.

Cat Detection

It knows when your
cat is typing.

MeowProof quietly watches for the telltale signs in the background. It never interferes with your own typing — no matter how fast you go.

Frantic bursts

Keys flying way faster than any human would ever type

Whole-paw pressing

Multiple keys held down all at once — like a paw resting on the keyboard

Total key chaos

A wild random mix of letters, numbers, and symbols — all in one go

Sitting on a key

One key held down for way, way longer than any person would

Resets automatically after 5 seconds of no input and never affects your own typing.
