What is CFInsights?↵
----↵
↵
**CFInsights** is a web app that helps you deeply analyze your Codeforces performance and track your improvement.↵
↵
It uses the official Codeforces API and gives you clean, easy-to-read dashboards — whether you're just starting out or already a specialist.↵
↵
**You don’t need to sign up. Just enter your handle and get a full breakdown of your CP journey.**↵
↵
The Two Modes — Solo & Compare↵
----↵
↵
**CFInsights** has two powerful modes:↵
↵
**Solo Mode** ↵
Enter your own handle and get:↵
↵
- Rating history graph ↵
- Last 7 contests with rank and rating change ↵
- Upcoming contests ↵
- Language usage pie chart ↵
- Submission verdict distribution ↵
- Problem tag frequency ↵
- Difficulty breakdown (Very Easy to Very Hard) ↵
- Last 10 unsolved problems ↵
- **CFInsights Rating Score** — our custom rating that tells how strong your profile is overall ↵
- A practice dashboard built just for you based on your weak areas↵
↵
And that’s not all — there’s even a heatmap and an advanced analysis section.↵
↵
**Compare Mode** ↵
Enter two handles and we compare:↵
↵
- Rating graphs side by side ↵
- Contest history ↵
- Problem type and tag coverage ↵
- Difficulty analysis ↵
- Custom score for each user using the same formula ↵
- “After X contests” analysis (performance until Xth contest) ↵
- Verdict breakdowns, most used languages, upsolve behavior and more↵
↵
Why I’m Building This (And You Might Feel the Same)↵
----↵
↵
I often open Codeforces after a contest and feel stuck. ↵
_"Did I do well? Why did my rating drop again? Am I actually improving or just showing up?"_↵
↵
Sometimes I solve a bunch of problems, but still feel lost. ↵
No idea what my weak topics are, what’s working, or what’s just noise.↵
↵
Worse — when I see others improving faster, I start feeling that familiar FOMO. ↵
_"What are they doing that I’m not?"_↵
↵
CF has rating graphs and submission lists, but it doesn’t give me **clarity**. ↵
I don’t want raw data — I want **insight**. Something that tells me where I stand, and what I should fix.↵
↵
That’s why I’m building **CFInsights** — to give myself and others the kind of performance visibility a coach or mentor would provide. ↵
It’s like a fitness tracker — but for competitive programming.↵
↵
↵
