    Ranked by bypass resistance, schedules, time limits, platforms and price · Updated

    The best website blocker for focus is one you cannot switch off in the moment you want to.

    Key takeaways

    • System-level blockers are harder to bypass than extensions: they cover every browser and can be locked.
    • Freedom is the only option here that blocks your phone and computer in one session.
    • LeechBlock NG is the best free blocker, with schedules and time limits in the browser.
    • Blocking limits you cannot override work better than reminders: in a study of about 2,000 adults, they cut social media and browsing time by 22 minutes a day.
    • For studying, a timed block during each study session is the simplest setup. Adding a Pomodoro timer splits the session into work periods and short breaks.

    Setups for studying and work

    Study sessions: block social media, video and news sites for the length of each session with a timer lock, for example 2 hours.

    Workday schedule: block the same sites every weekday from 9 AM to 5 PM, and leave evenings open.

    Daily time limits: allow a set amount, such as 20 minutes of social media a day, then block it until tomorrow.

    Pomodoro sessions: block distracting sites for the whole study period, then work in 25 minute sessions with 5 minute breaks. Keep the block on during breaks, so a break does not turn into an hour on YouTube.

    Exam season: lock your blocks until the day after your last exam, so they cannot be changed on a bad night.

    Frequently asked questions

    What is the best website blocker for studying?

    For Windows, Ascension or Cold Turkey, because a locked block holds for the whole session. For phone and laptop together, Freedom. For a free option, LeechBlock NG.

    What is the hardest website blocker to bypass?

    System-level blockers with locks: Ascension, Cold Turkey and FocusMe with Enforced stopping. Browser extensions are the easiest to bypass because they can be removed in one click.

    Do website blockers actually work?

    Blocks you cannot override work better than reminders. In a randomised study of about 2,000 adults, limits that could not be immediately overridden reduced time on social media, browsers and YouTube by 22 minutes a day.

    Can I use a website blocker with the Pomodoro technique?

    Yes. Ascension and FocusMe include a Pomodoro timer. With other blockers, run a separate timer alongside them.

    What is the best free website blocker?

    LeechBlock NG. It is free, works in Chrome, Firefox, Edge and other browsers, and supports schedules and time limits.

    What is the difference between a browser extension and a system-level blocker?

    An extension works inside one browser and can be removed in one click. A system-level blocker is installed on the computer, covers every browser and can be locked so it cannot be removed during a block.

    Can I block websites only during work or study hours?

    Yes. Ascension, FocusMe, LeechBlock NG, StayFocusd and BlockSite support schedules, and Cold Turkey and Freedom support them on paid plans.
