What is this site?

cf-tracker is a website for monitoring progress on codeforces.com in terms on which problems were solved in contests.

There are two types of problems to keep track on:

  • The ones that were solved during the contest.
  • The ones that were not solved during or after the contest [problems to upsolve later].

It also provides feature to filter contests based on division [div1, div2, div3, Educational Rounds], and is pretty damn quick about it.
