Code Force is a community of top-talented coders. With our mission of challenging, entertaining, and educating aspiring engineers—we are the only place to be! We have our own challenges (CF Challenges), and for even more variety, we have a forum where you can discuss any issue or post the solutions to any problem.

Here you will find CF stalker, a free Chrome extension that will help you better understand what happens during the code competition in just a few seconds. This is thanks to an improved web page design.

With this tool you can:

Get quick statistics about problems solved by each user, from the whole year up to the present day. Filter them by their tags, like algorithms and mathematics. Select the month or day to see how many problems were solved during the selected period. View them one by one.
