About

You opened YouTube "just for a second" — and lost an hour. Again.

SiteBlocker puts you back in control. Block distracting sites, lock yourself out when willpower runs low, and see exactly where your time goes. Over 2,000 users on Chrome and Firefox.

Every blocking feature is free. Pro is for when you need the blocks to actually hold.

——— FREE ———

BLOCK DISTRACTING SITES
Add any site to your blocklist with one click. Right-click a page to block it instantly. Keep 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, with built-in Pomodoro breaks. Soft mode lets you stop anytime. Hard mode makes you type a passphrase before you can bail early.

WHITELIST MODE
The nuclear option: block the entire internet except the sites you approve.

INSIGHTS
See where your time goes — total blocks, your current streak, and your most-blocked sites. All data stays on your device.

——— PRO ———

LOCKED MODE
Lock a focus session or a blocklist and there's no quit button until the timer runs out. No disable, no edit, no delete, no passphrase escape hatch. For the moments willpower alone won't cut it.

ACCOUNTABILITY PARTNER
Pick someone you trust. The moment you try to unlock early, they get an email. Knowing they'll see it is usually enough to keep you honest.

DAILY TIME LIMITS
Give yourself 10 minutes of YouTube a day. Hit the limit and the site locks for the rest of the day.

KEYWORD BLOCKING
Block any page containing words like "gambling," "betting," or "clickbait" — in the URL, page title, or page content. Catches distractions you didn't plan for.

FULL INSIGHTS DASHBOARD
Weekly activity charts, an hour-by-hour distraction heatmap, focus-session analytics, and your top time sinks with favicons. See the patterns, then break them.

——— MORE ———
- Sync blocklists across Chrome and Firefox
- Dark mode
- Password-protected blocklists
- Motivational quotes on the blocker page
- 8 languages: English, Spanish, French, German, Japanese, Korean, Portuguese, Romanian

FREE FOREVER
All blocking features. No limits. No trial. No credit card.

Pro unlocks Locked Mode, accountability emails, daily time limits, keyword blocking, and the full insights dashboard:
$2.99/mo · $24.99/yr · $49.99 lifetime
