Who each one suits

Cold Turkey Blocker

  • People who talk themselves out of softer blockers mid-session
  • Buyers who want a one-time purchase instead of a subscription
  • Blocking desktop applications and games as well as websites

LeechBlock NG

  • People who want a free site blocker inside the browser they already use
  • Rationing a site by time allowance rather than blocking it outright
  • Users who want fine control with wildcards, keywords and regular expressions

Worth knowing

Cold Turkey Blocker

  • Windows and macOS only: the vendor states that Linux, ChromeOS, Android and iOS are not supported.
  • The free version blocks websites only; application blocking, schedules, locks, breaks and allowances need Pro.
  • The vendor's pricing page did not show the Pro price as readable text; the $45 figure comes from a Zapier roundup updated in August 2026.

LeechBlock NG

  • It blocks only inside the browser where it is installed; other browsers and desktop apps are unaffected.
  • The developer says it is not designed for parental control or for blocking offensive content.
  • There is no macOS or iOS version; the site points to ivBlock, a separate product based on LeechBlock.
  • The browser may still connect briefly to a blocked site, so the developer suggests a HOSTS-level blocker when no connection at all is wanted.

Key features

Cold Turkey Blocker

Website blocking with wildcards
Block whole domains, single URLs, YouTube channels or search keywords, using wildcards for patterns. Blocking everything and listing exceptions turns it into an allow list.
Application blocking
Pro blocks applications or whole folders of them. On Windows it can also block Microsoft Store apps and match on window titles.
Locks
A block can be locked by timer, time range, delay, restart, password or a string of random text up to 5,000 characters. A locked block also prevents uninstalling the app.
Weekly schedule
Pro lets you drag blocks onto a schedule that repeats every week, and can lock, log off or shut down the computer at set times.
Breaks and allowances
Pro adds Pomodoro cycles that switch blocking on and off, time allowances for blocked items, and breaks earned after a set period of work.
Usage statistics
Tracks website and application use to show your main distractions. The data stays on your computer and can be exported as JSON.

LeechBlock NG

Block sets
Up to 30 sets of sites, each with its own list, days and times. Lists accept wildcards, exceptions and keywords that match words in a page's title or text.
Time periods and time limits
Block within fixed periods such as 9am to 5pm, after a time limit such as 10 minutes in every hour, or with both combined. Unused time can roll over to the next period.
Lockdown
Blocks the sites in chosen block sets immediately for a duration you specify, outside their normal schedule.
Delaying and password pages
Instead of a plain block, a page can show a countdown before letting you through or ask for a password. A custom blocking page can also be set by URL.
Access control
A password or a random access code can guard the options page, to slow down any attempt to change settings in a weak moment.
Temporary override
An optional override lifts blocks for a set number of minutes, with a cap on how many overrides are allowed in an hour, day or week.
