I made a site called CF Random Unsolved. It gives you a random Codeforces problem you have not solved yet. You can set the difficulty, pick tags, and you do not need any login. Just type your handle and get a random problem.
Why I felt the need to create this
- Picking a problem from problemset took too long and broke my flow
- I wanted new problems every time without repeats without scrolling the problemset
- Filtering by rating or tags felt slow and tedious
- I needed something that works instantly without login even on my phone
Why it helps
- No more searching for the next problem
- Every problem shown is new for you
- Easy to focus on a rating range or topic
- No login needed
- Fast to use and good for daily practice
