CF Analytics Chrome extension improves the Codeforces profile webpage to include statistics of problems solved by the user. The ‘Problem Rating’ graph is a bar chart showing problems solved for each problem rating. The ‘Tags Solved’ graph is a doughnut chart displaying tags solved across any problem and also lists a count for each tag. The ‘Unsolved Problems’ shows a count of all problems attempted with not correct verdict and also lists them.

The extension communicates only with the Codeforces API and runs entirely on the browser.
