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=countryto 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.standingsanduser.info - Rated users cache refreshes every 24 hours
How to install:
- 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.
- And done!! You are good to go!
If you have any suggestions or feedback, please feel free to share them. Your comments are welcome and will help me improve it further. I will try to release standalone browser extensions soon!

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
IsCheaterandPredictedIsCheater, We consider a pass beingIsCheater^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.
Im pretty sure you can get pretty high scores by always guessing that hes a cheater!
For some reason, the extension isn’t working for me (I also waited a long time for it to fully load).
Your tampermonkey is disabled. Enable it by clicking on Enabled

Check if your tampermonkey is Enabled or not. https://mirror.codeforces.com/blog/entry/151693?#comment-1351427
If not, Enable it
i found no script is running by it. Where to go for it? in image too its showing
what to do now?
It's enabled already you can see it in images too. tick mark/i checked again too .still same
Still if it doesn't work try updating your browser or try a different browser
oh ya, i tried all things possible and added script again too,it's finally working. It seems it shows for both Div2 and Div1 combine only
I will add more features in future updates, this is an experimental version
Honestly this would be great to catch cheaters and to use in APIs
