Hey Codeforces!

As someone who’s passionate about competitive programming, I always found myself jumping between user profiles, checking past contests, and manually analyzing performance trends — so I thought, why not build a tool that does all of this automatically?

I’m excited to introduce CF Stalker — https://cf-stalker-web.onrender.com/ , a clean and simple Codeforces companion with features designed just for you.

### Stalker Mode Enter any Codeforces handle and unlock:

Solved Problems by Date – See when problems were solved.

Rating-wise Breakdown – View problems grouped by their rating.

Topic Tags – Explore what topics a user has practiced more (or ignored).

It's like viewing a user's submission history... but actually useful and organized.

### Contest Analyzer Analyzing contests manually? Not anymore.

My analyzer fetches and processes the last 50 contests from each division (Div 1 to Div 4), showing:

Topic Distribution – What topics appear most often?

Rating Distribution – Are Div 2 contests getting harder?

Trends Over Time – Visualized with interactive charts.

And yes — it stays up to date automatically.

### Live Now: https://cf-stalker-web.onrender.com/ Try it out, stalk your friends (ethically, of course), and find out how strong (or lazy) your prep really is.

Open to Suggestions!

This started as a side project, but I’d love to grow it with feedback from the community. Got ideas? Found a bug? Let me know in the comments or DM me.

Let’s keep improving, one stalk at a time
