Pages loaded in a real browser, not just an HTTP request. Route discovery is best-effort — nav links not in the initial DOM are not followed. How we check

Its embedding policy changed6 days ago

We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.

What it does

A competitive coding platform built around DSA problems, real-world challenges and timed contests, with AI-assisted code review, achievements and global leaderboards. It renders entirely in the browser, so an HTTP check confirms the server answered but says little about whether the app itself loaded — the browser probe is the honest check here.

What people say

No reviews yet.

We would rather show none than invent them.

Embed this status

Put it in your README. It updates itself every time we check, and links to your verification record — evidence a stranger can read, not a page selling them something.
