Most keyboard-locking apps were built for cleaning the keys. Cats Lock is built for the cat moment. What stands out: • Smart Detect locks automatically when it senses a cat, fully on-device, no Input Monitoring • Stealth Lock: silent and invisible, for meetings • Custom warning sounds, or import your own • ⌘L from the menu bar or main window • Sandboxed. No analytics, no account • $2.99 one-time, no subscription Built by an indie developer for himself and his cat.

Hey Product Hunt 👋 I'm Todd, and Cats Lock is the result of my cat repeatedly walking across my keyboard during work calls and sending things into Slack I cannot legally share here. I figured a small, focused utility that just does the one thing would be useful for anyone else living through this. So here it is. A few details worth knowing: • ⌘L locks the keyboard from the main window or menu bar, ⌘L again unlocks • Standard mode shows a friendly overlay with a customizable warning sound on each blocked keypress (also great as an audible cue from the next room when your cat has joined the keyboard) • Stealth Lock mode is silent and invisible, useful during meetings, recordings, or calls • Sandboxed, no Accessibility prompt, no analytics, no account creation • $2.99 one-time, no subscription Happy to answer any questions today, and I'd love to hear your "what my cat typed" stories. 🐈

The #1 request since launch was "can it just lock when the cat shows up?" It can now. 🐈

Smart Detect watches for cat-style typing (several keys held at once, rapid scattered bursts) and locks the keyboard on its own, so you don't have to reach for the shortcut when a paw lands. The part I'm proudest of: it runs entirely on your Mac, uses no Input Monitoring, and is opt-in and off by default. If it ever guesses wrong, one tap on "That wasn't my cat" unlocks and helps it tune.

Everything else is still there: ⌘L from anywhere, Stealth mode for meetings, custom sounds. Still $2.99, one time, no subscription. Update on the Mac App Store, and keep the requests coming, that's how this shipped.
