recently i've been thinking, what if codeforces had something like faceit? so with assistance of Claude AI, i went ahead and built:

CFSTATS:

it shows all your stats and progress: rating history, problem breakdowns, activity heatmap and stuff like that. code is open source on github if you wanna check it out

also just to be clear, it doesn't make matches like faceit does in cs2, it's purely a stats tracker ;)

p.s.: i didn't do anythin bc i am a vibe-coder :O
