Show HN: Debategle – ranked 1v1 debates judged by an LLM

A developer launched Debategle, a platform for live 1v1 debates where an LLM judges the winner, using FastAPI, Clerk for auth, and an Elo-style rating system. The creator acknowledges potential flaws in LLM judging but argues it scores argument structure and rebuttals effectively.

I built Debategle, a platform for live 1v1 debates. You get matched with a random opponent ranked matching is based on topics you’re interested in, casual matches are just open rooms , you each argue your side, and an LLM judges who made the better case. Stack: FastAPI backend, Clerk for auth, Elo-style rating system for ranked matches. The obvious objection is LLM-as-judge reliability, I don’t think it’s perfect, but I’ve found it’s decent at scoring argument structure and rebuttals rather than just rewarding confident-sounding text. Curious what people think breaks it, I’m sure there are ways to game the judging that I haven’t found yet.
