Commit Lock is a free Chrome add-on designed to help users stay focused by blocking distracting websites until a code commit is made on GitHub. This tool is particularly beneficial for developers looking to maintain their productivity and build commit streaks. Users can easily connect their GitHub account securely with read-only access and configure a customizable blocklist that includes popular distractions like Twitter, Facebook, and Instagram.

The functionality of Commit Lock revolves around its simple yet effective mechanism. It automatically checks for commits every 30 minutes, ensuring that blocked sites remain inaccessible until a commitment to code is fulfilled. With features like local timezone awareness and a configurable commit threshold, this tool offers flexibility and accountability for anyone who wishes to limit their scrolling time and enhance their focus on coding tasks.
