AlgoArena

Race a stranger on the same coding problem live, with chess-style Elo ratings.

Webunknownglobal

AlgoArena stages live head-to-head races on the same coding problem, scored with chess-style Elo ratings, inside a real IDE with judged tests. Guided courses and a builder workspace extend the practice loop, and assessments stay replayable with linked evidence. It adds the pressure and ranking that solo problem-grinding lacks.
