Now you can add a “Country Standings” tab to Codeforces contest/gym standings pages.

The goal is simple: quickly see how participants from a specific country performed — including teams — without manually searching the full standings!

Key features

  • New “Country Standings” tab: Appears next to the normal standings menu and uses URL mode ?cs=country to make it ready to share with friends!
  • Country filter for both individuals & teams: Works for solo participants and teams automatically, A team is included if any member of the team matches the selected country
  • Extra profile info: Shows avatar, rating pill, full name + city, and organization/institute (if present on CF profile)
  • Uses Codeforces API: user.ratedList, contest.standings and user.info
  • Rated users cache refreshes every 24 hours

How to install:

  1. Download Tampermonkey extension for Chrome Firefox Microsoft Edge/Edge Mobile

2. Install the CF Country Standings script from here.


Click on Install this Script
Click on Install Again inside the Tampermonkey tab.

  1. And done!! You are good to go!

I just thought of a cool game to play by using this extension and the cf cheater database.

Here are the rules. We first install this extension, and disable CF cheater database. Next filter by the country "India".

Repeat the following process indefinitely, each time successful adding 1 to your score. If you fail the game is over. Assume the predicate IsCheater and PredictedIsCheater, We consider a pass being IsCheater^PredictedIsCheater=0, and a fail otherwise.

Look at the top K (K can be changed but lets default to 100) and have a random number generator pick a submission. Check his submissions for the problems in the contest, and make a verdict PredictedIsCheater, check sucess by reenabling CF cheater database. If he is a cheater and reported, award yourself 1 point. Otherwise if he is not a cheater and you think he is, report him to the cheater DB and unfortunately you lost. Otherwise you guess wrong. Sorry.

If you guess sucessfully, congrats! Add 1 to your score and disable cheater database again. Go to the next contest down the contest list and repeat the process!

Please report your high scores as responses! I hope you enjoy this little game.

Fun fact

For some reason, the extension isn’t working for me (I also waited a long time for it to fully load).

Honestly this would be great to catch cheaters and to use in APIs
