uttamsingh3137/CodeBet ? reverse-engineered prompt

Build me a full stack web app called CodeBet where programmers can challenge each other head to head in 1v1 coding matches.

I want the experience to feel like a mix of competitive programming and chess, where two people can create a challenge, join a match, solve the same problem, and feel the pressure of a live contest together. Include a clean frontend for browsing challenges, starting a match, seeing the opponent, and tracking progress. On the backend, handle users, match creation, challenge invites, and the game flow so both players stay in sync. Make it feel real time if possible, and keep the whole thing polished and easy to use. If you need to look up current docs online to make the best version, go for it.
