It's not a willpower problem
You didn't plan to lose an hour before lunch. It happened one reflex-click at a time. The most distracting sites on the internet are engineered to sit one tab away, and willpower is a poor defense against a habit you've practiced thousands of times.

AsurionThe fix isn't more discipline, it's a little friction. Making a distraction harder to reach than the work is enough to break the reflex. That's the whole idea behind learning to block online distractions without willpower.
Track, block, refocus
The whole loop runs locally in your browser.
Track
Time Blocker quietly records how long you spend on each site, every day. No timers to start, no setup. It just runs in the background.
Block on a schedule
Add the domains that derail you and choose when they're off-limits, whether all day or only during your focus hours. It blocks the whole site, not one page.
Refocus
Open a blocked site inside a focus window and you land on a calm focus page instead of the distraction: a small, well-timed nudge back to work.

Time tracking

Website blocking

Remote workers & developers
Keep news and feeds shut during deep-work hours, without closing the tabs you actually need.
Writers & creators

Anyone fighting the scroll
Put a gentle gate between you and the doomscroll, on a schedule you set once.
Why people choose Time Blocker
Most blockers either upsell a subscription or quietly sync your activity to the cloud. Time Blocker does neither.
100% private
Your time data lives in your browser's local storage. Nothing is uploaded, so we literally can't see your browsing.
Free, with no catch
No paid tier, no trial timer, no account to create. Free on Chrome and Firefox, full stop.
Gentle by design
Blocked sites show an encouraging focus page, not a guilt trip. Nudges, not punishment.
Tracking + blocking together
Most tools do one or the other. Time Blocker measures your time so you block the sites that actually cost you.
Chrome and Firefox
Ships for Chrome (MV3) and Firefox (MV2) from a single codebase, the same experience either way.
Honest about scope
It does scheduled blocking and per-site tracking. It isn't a quota timer, and we won't pretend otherwise.
