**Hello Codeforces! ** I’m excited to share a personal project I’ve been working on: CF Tracker — a full-featured analytics tool to help you and your friends monitor progress on Codeforces with clean visualizations and real-time stats.

** What is CF Tracker?** CF Tracker is a full-stack web app that uses the Codeforces API to provide deep insights into your performance, consistency, and strengths as a competitive programmer.
Whether you want to stay consistent, analyze your weaknesses, or compare with friends, this tool is built for you.
** Key Features** ** Today's Stats** ****Problems solved today
- Number of submissions
- Verdicts: AC, WA, TLE, etc.
- Problem rating distribution for today
** All-Time Statistics** - Problem Solving Progress (line chart – 30 days, 6 months, all time) - - Contest Rating Graph (rating, rank, rating changes) - - Submission Activity Heatmap - - All-Time Rating Distribution - - Verdict Distribution - - Top Problem Tags
** Multi-User Leaderboards** Just enter multiple handles separated by commas:
- Today’s Leaderboard
Rank | Handle | Solved Today | Submissions | Rating | Last Active
- All-Time Leaderboard
Rank | Handle | Total Solved | Current Streak | Avg Attempts/AC | Rating | Last Active
** Tech Stack** - Frontend: HTML, CSS, JavaScript (Chart.js) - - Backend: Python (Flask) - - Data Source: Codeforces Public API
** Why I Built This** As a fellow Codeforces user aiming to grow and improve, I often found myself wondering:
How consistent am I really?
Which ratings am I most comfortable with?
What tags do I solve the most?
How do my friends stack up against me?
So, I built CF Tracker to get those answers — and I hope it helps others too!
** I’d Love Your Feedback!** If you’re interested in trying it out, contributing, or just want to say hi — feel free to drop a comment.
Let’s keep improving together!
