Hello CF,
I've seen a lot of people say very good things about a2oj ladders but I never used it because the problems in it are very old, as it was constructed by ahmed_aly 4-5 years ago, so I decided to try to recreate the ladders with updated data of codeforces, especially because nowadays CF is quite ad-hoc (and I like it:D).
I mostly followed the same procedure as described here, with some little changes, and then I deployed it on https://c2-ladders.com
If you want to learn more about how I did it, I've uploaded a video on how I constructed it, which you can see here.
The website and the script both are open source, feel free to make a PR if you want some change or just tell me in comments.
