Thank you so much for the positive feedback. Now Caucus natively supports codeforces and atcoder questions.

If you find any bug please create an issue on github and let me know. https://github.com/Rishabh-malhotraa/caucus/issues

Enter Coderforces/Atcoder Link	Atcoder Question	Codeforces Question

PS: if two people are collaborating (A & B) and A searches for a question of codeforces then other B automatically get the questions user A searched for.(Problem Page is synced across all the users that are collaborating)

Please consider giving the repo a star on Github if you liked the project. Cheers!
