Deep Focus – Site Blocker & Pomodoro

Block distracting sites for a focus session, Pomodoro style, with a calm block page and stats that stay on your computer.

Deep Focus is a focus timer that actually blocks the sites you list, with nothing stored anywhere but your own browser. START IN ONE TAP Pick 25, 50 or 90 minutes (or your own), name what you're working on, and press Start. Blocked sites redirect to a quiet page with your task and the time remaining. TWO MODES Blocklist mode blocks the sites you list. Deep-work mode blocks everything except the sites you list. Preset packs for social, video, news, shopping, games and AI chat get you going in seconds. STRICT MODE For people who disable their own blocker in four seconds: no pause, no stop, no emergency unlock, and the list is locked until the session ends. SURVIVES A RESTART The timer is anchored to a timestamp, not a running clock. Close Chrome and reopen it and the session is exactly where it should be, still blocking. BREAKS AND CYCLES Short and long breaks, cycle counting, auto-start or wait for a click, desktop notifications when a phase ends. STATS THAT STAY PRIVATE Focus minutes per day, a 12-week heatmap, streaks, most-blocked sites and per-task totals, all computed and stored locally. Export as JSON or CSV. HONEST ABOUT THE LIMIT Chrome lets anyone disable an extension from chrome://extensions. Deep Focus does not pretend otherwise. It adds friction, not a wall. PRIVACY No server, no account, no analytics. The extension makes no network requests.
