Blocker is a free Chrome add-on developed by blockeronline that aims to improve productivity by allowing users to block distracting websites. With Blocker, users can create rules to block specific websites by name, ensuring that they stay focused on their work and avoid time-wasting activities.

One of the key features of Blocker is the ability to use wildcards to block entire domains or subdomains. For example, users can block everything that starts with "website.com" by simply entering "website.com/*" in the rule. This allows for a more comprehensive blocking approach, ensuring that users stay away from any distractions associated with specific websites.

Blocker also offers options for users to choose between outright blocking access to a website or setting a time buffer between them and the site. This time buffer can be helpful for those who need occasional access to certain websites but want to limit their time spent on them.

Additionally, Blocker provides the option to remove references to distracting sites from other websites. This feature helps to eliminate temptations by overriding links and other mentions of blocked websites on other sites, further reducing the risk of distraction.

To prevent further editing and maintain focus, Blocker allows users to lock down the rules they set for themselves. This ensures that once the rules are in place, they cannot be easily modified or overridden, helping users stick to their productivity goals.

Blocker is a valuable tool for anyone looking to increase their productivity by minimizing distractions from websites. Its user-friendly interface and customizable blocking options make it a useful addition to the Chrome browser for those who want to stay focused and make the most of their time online.
