The Codeforces Ratings extension is a Chrome add-on that streamlines the process of tracking competitive programming ratings. With this tool, users can easily check their own and their friends' current and maximum ratings on the Codeforces platform without needing to navigate away from their browser. The extension is designed for both novice and experienced programmers, making it accessible for everyone in the coding community.

Key features include instant rating updates and the ability to track friends by simply entering their Codeforces usernames. This functionality helps users stay engaged with their peers and fosters a competitive spirit. However, it should be noted that during ongoing contests, the extension may not provide data updates, which could affect its usability at those times.
