Simple Free Site Blocker

Block the distracting sites you choose during timed focus sessions. Free, private, no account.

Simple Free Site Blocker is completely free and helps you stay on task. Pick the sites that pull you away, start a focus session, and those sites are blocked until the timer ends — then you get a break. • One click to start a focus session (25 minutes by default; change it any time) • Add sites in seconds — one-click quick-add by category (Social, Gaming, News & entertainment), or paste a whole list at once • Tabs already open on a blocked site are moved to a calm "Stay with it" page • Focus and break alternate automatically — press Start once and the timer runs the number of focus + break cycles you choose, then stops by itself • See your own numbers: sessions completed, minutes focused, and distractions blocked • Free, no account, no ads
