Regex URL Guard

About

Regex URL Guard helps you limit website access using domains or regular expression URL
  patterns.

  Create rule groups for sites such as social networks, video platforms, news sites, or
  any custom URL pattern. For each group, you can set daily time limits and blocked time
  ranges by day of the week, giving you fine-grained control over when and how long
  certain pages can be used.

  Key features:
  - Match websites by domain or JavaScript regular expression
  - Set daily time limits for each URL group
  - Configure blocked time ranges for each day of the week
  - Use blacklist or whitelist mode
  - Show a built-in blocked page or redirect to a custom URL
  - View remaining time with the extension badge
  - Receive notifications before time runs out or when blocking is triggered
  - Export and import settings as JSON
  - Use Lock Mode to prevent same-day rule changes from taking effect immediately

  Time is counted only while Chrome is focused and the matching page is active in the
  current tab.

  Regex URL Guard is useful for reducing distractions, limiting social media or video
  sites, and keeping browsing habits aligned with your schedule.
