Chrome extension tracking upcoming competitive programming contests across platforms

Browser extensionfree

AlgoRadar is a free, open-source Chrome extension that tracks upcoming competitive programming contests across Codeforces, AtCoder, LeetCode, CodeChef, Kaggle, and more, with filters by platform and time window. Contest data is served from scheduled cached updates, aimed at competitive programmers who want one place to see what contests are coming up instead of checking each site separately.
