BlockSite alternatives: 5 website blockers compared (2026)

BlockSite is the extension most people install first, and for a reminder it is fine. People look elsewhere when the block has to survive a trip to the extensions page, cover apps and other browsers, or run on a schedule without a subscription whose price keeps changing. Here are five alternatives and the catch in each.

Prices and platforms checked on each vendor’s site on 14 October 2026.

Why people look for an alternative

  • It is an extension. Anything that lives in one browser is one click from off, is off in private windows by default, and knows nothing about the other browser on the same computer.
  • Pricing is hard to pin down. The website offered a $39.99 lifetime deal “for a limited time” when checked; the app stores list several monthly and annual subscriptions at different amounts.
  • Apps need another app. Blocking a desktop program is not what an extension does; BlockSite’s desktop app and phone apps are separate installs with their own plans.

Which one?

If BlockSite’s job is a nudge in one browser, LeechBlock NG does it free and better. If the block has to hold, cover apps and every browser, and run on a schedule, FocusMe is the alternative built for that: an application rather than an extension, with four strictness levels, Enforced Mode and an accountability partner, on the computer and the phone. Freedom and Cold Turkey are the other two applications on this list, each with its own trade-off.
