LeetCode Rating Analytics

A browser extension that provides a rating-based statistical breakdown of your solved LeetCode problems, similar to CF Analytics for Codeforces.

Features

  • 📊 Problem Rating Distribution: A bar chart showing the count of solved problems in different rating brackets.
  • 🍩 Tags Solved Distribution: A donut chart showing the breakdown of solved problems by topic/tag.
  • 📈 Community-Sourced Ratings: Uses the community-maintained zerotrac/leetcode_problem_rating dataset for objective problem ratings.
  • smartly Handles unrated problems by excluding them from the charts and showing a separate count.

How to Install (for testing)

Since this is not on the Chrome Web Store, you need to "sideload" it locally.

  1. Download: Download the leetcode-analytics folder containing all the files (manifest.json, popup.html, etc.).
  2. Open Chrome/Edge Extensions: Go to chrome://extensions or edge://extensions in your browser.
  3. Enable Developer Mode: In the top-right corner, turn on the "Developer mode" toggle.
  4. Load Unpacked: Click the "Load unpacked" button that appears.
  5. Select Folder: In the file dialog, select the entire leetcode-analytics folder.

The extension icon should now appear in your browser's toolbar!

How to Use

  1. Click the extension icon in your toolbar.
  2. Enter your LeetCode username in the input field.
  3. Click the "Fetch" button.
  4. View your analytics!

Next Steps

  • Implement the real LeetCode GraphQL API call to fetch a user's actual submission history, replacing the current mock data function.
