BlockSite Chrome extension

BlockSite blocks distracting websites and apps using blocklists, time limits, and scheduled Focus Mode. It suits anyone who keeps opening the same time-wasting sites out of habit. The catch: cross-device sync and some advanced controls need a paid plan, and it asks for access to your browsing history.

What BlockSite does

BlockSite stops you from opening chosen websites and apps, either permanently or on a schedule. You build a blocklist, then choose how strict it is: a hard block, a daily time limit, or a Pomodoro-style Focus Mode that alternates work and break periods. It also offers a Schedule Mode so sites are only blocked during set hours, like your normal workday.

BlockSite free vs paid

The core blocking, Focus Mode, and Schedule Mode features are available for free. The listing doesn't spell out every paid feature, but cross-device sync, deeper analytics, and some customization options are typically part of a premium plan sold through the companion mobile apps and account system. Most casual users can get real value from the free tier alone.

Is BlockSite safe?

BlockSite's Chrome Web Store listing discloses that it handles web history, which it needs to detect and block sites as you browse. This is a core requirement for any website blocker. Review the permissions prompt on install and only proceed if you're comfortable with an extension monitoring the sites you visit in order to block them.
