Hover over your Codeforces activity heatmap to see daily submissions, accepted count, accuracy percentage, and deep analytics. CF StatLens upgrades your Codeforces profile by replacing the default activity heatmap with a powerful, zero-lag analytics tooltip. Why install CF StatLens? The default Codeforces heatmap only shows the number of submissions. CF StatLens injects granular, competitive analytics directly into your hover state, helping you track your actual grind and problem-solving trajectory. Key Features: • Instant Daily Stats: Instantly view Total Submissions, Accepted count, and Failed attempts for any specific day. • Accuracy Tracking: A visual progress bar showing your exact accuracy percentage for the day. • Difficulty Breakdown: See exactly what rating of problems you solved (e.g., Rated 1200, Rated 1400) color-coded by difficulty. • Top Topics: Identifies the algorithmic tags you practiced most on that day (e.g., Math, Greedy, DP). • Personal Best Tracking: Automatically calculates and displays your "Top Grind" (most active day) and "Best AC" (most productive day) at the bottom of the tooltip. • Streak Calculator: Displays a fire badge highlighting your continuous local daily submission streak. Engineered for Speed: CF StatLens uses a custom O(1) local caching architecture. It fetches your data from the Codeforces API exactly once and saves it directly to your browser. This means zero lag on hover, lightning-fast rendering, and complete immunity to API rate-limiting!
