CF Analytics

CF Analytics is a powerful Chrome extension designed to enhance your Codeforces profile page by adding detailed statistics about problems you've solved. It features a 'Problem Rating' bar chart that visually represents the number of problems solved per rating level, helping you track your progress across difficulty tiers. The 'Tags Solved' doughnut chart breaks down your solved problems by tags, giving insights into your strengths across different problem categories. Additionally, the extension displays a list and count of 'Unsolved Problems'—those attempted but without a correct verdict—so you can focus on improving where needed.

Running entirely in-browser, CF Analytics interacts solely with the official Codeforces API, ensuring your data privacy and security. This tool is perfect for competitive programmers seeking a deeper understanding of their performance and aiming to strategize their problem-solving practice more effectively.
