Overview
Analyze Codeforces performance—solve time, failure rates, rating changes, errors by division/time, online friends & submissions.
Track your Codeforces performance with clear insights into solve times, failure rates, rating changes and problem-level errors, broken down by division and time range. Filter by contest type and focus on selected topics, rating ranges to quickly spot weak areas and improve efficiently, all on your profile page. Also see online friends and their submissions on the problem you're viewing. How it works Runs entirely client-side on `codeforces.com`. Fetches from public Codeforces APIs (`user.status`, `contest.list`, `user.rating`, `problemset.problems`, `user.info`, `contest.status`). No server, no tracking, all in your browser.
