KeepCode by dngi

KeepCode is an open-source browser extension that automatically tracks your LeetCode problem-solving progress—so you can focus on learning and practicing, not on manual record-keeping. As you solve problems, KeepCode quietly saves your progress, including problem titles, difficulty, tags, and timestamps. Instantly view your recent activity, filter by tags, and review your full history—all from a beautiful popup or the options page.

I am currently the sole developer and welcome your feedback, suggestions, and contributions to make KeepCode even better!

🚀 Automatic Progress Tracking: Your solved LeetCode problems are detected and saved automatically—no manual input required.
🏷️ Tag & Difficulty Filtering: Filter your solved problems by topic tags or difficulty to focus your review.
🕒 Recent Activity at a Glance: See your latest solved problems directly from the popup.
📋 Full History & Search: Browse and search all your solved problems on the options page.
