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.
