When your time's up, a big cat takes over your screen and holds it until you actually take a break. Works on any site you choose. Real footage, no AI.
Works on any site · real footage, no AI · no data collected · free
Most blockers are easy to ignore. A full-screen animal staring back at you is not.
Whole-browser, social-media presets, or your own custom list, not just a handful of hardcoded sites.
Counts only active time on the sites you chose, in the focused window, never idle or background tabs.
Your timer and breaks persist across page reloads, tab switches, and browser restarts.
A genuine lion or tiger, real footage cleanly cut out. No AI-generated "slop."
Click the animal while you wait for a little hit of calm. Breaks should feel nice.
No accounts, no analytics, no tracking. Nothing ever leaves your device.
Three steps. Then forget about it until the cat shows up.
Add it to Chrome and choose which sites to watch, or the whole browser.
Choose your work limit, break length, and whether a lion or tiger guards the gate.
Hit your limit and the big cat takes the screen. Stretch, breathe. It leaves when your break's done.
Switch anytime in the popup. More may join the pride.
Calm, regal, immovable. The classic gatekeeper.
Intense, eyes locked on you. Harder to ignore.
Lion Gatekeeper runs entirely on your device. It has no accounts, no analytics, no ads, and no tracking.
