Overview
You opened YouTube "just for a second" — and lost an hour. Again.
SiteBlocker puts you back in control. Block distracting websites, track where your time goes, and build real focus habits. Over 2,000 users on Chrome and Firefox.
BLOCK DISTRACTING SITES
Add any site to your blocklist with one click. Right-click a page to block it instantly. Create separate lists for work, study, and personal time.
SCHEDULED BLOCKING Block social media from 9 to 5. Block gaming sites during study hours. Set the schedule once — it runs automatically every day.
FOCUS MODE
Start a timed focus session when you need to lock in. Choose 25m, 45m, 1h, or 2h. Built-in Pomodoro cycles with break timers. Soft mode lets you quit early. Hard mode doesn't.

your device.
WHITELIST MODE
Nuclear option: block the entire internet except sites you approve.
