Codeforces Monolith — Major update

Revision en1, by state_invariant, 2026-06-07 21:09:28

This one's a fairly significant update — three features got meaningful improvements.

Dark Mode — the Codeforces logo had a white background even in dark mode. turns out the original logo doesn't play nice with dark backgrounds so i swapped it with an actual dark-mode version of the logo and cleared the white background from its parent elements. looks clean now.

Rating Predictor for Unrated Problems (the toggle on the problemset page) — wasn't estimating based on actual data before. now it builds a reference table from the last 4 finished contests per division and uses weighted nearest-neighbor by solve count to estimate. a problem with 15k solves in a Div.2 D slot lands around 1800–2000, not the same as one with 2k solves. way more useful.

Friends tab in Compare Dashboard — instead of typing handles manually every time you want to compare, there's now a friends dropdown. it loads your CF friends list (via the api or fallback to scraping /friends), click a name and it fills the input automatically.

If you are already a user the extension should have been updated.

Otherwise try Codeforces Monolith today:

lmk if anything breaks...

Happy coding...
