Debug. Duel.
Dominate.
BugCombat pits two developers against the same broken function. Fix the bug faster and cleaner than your opponent. The AI judges your speed and code in seconds.
Why BugCombat
Skill, judged by code — not by opinion.
Every duel is scored on four objective dimensions by an AI judge that reviews both submissions side-by-side. No favoritism, no rubric arguments.
Real-time
Live opponent presence
WebSocket-backed lobbies show when your opponent joins, types, and submits. No refresh, no guesswork.
AI judge
Four-dimension scoring
Correctness, cleanliness, efficiency, and security — each scored independently with written feedback.
Pro editor
Monaco in the browser
The same editor that powers VS Code, tuned with JetBrains Mono and a focused dark theme.
The process
From challenge to verdict in four steps.
Pick a language and difficulty. We spin up a private room with a unique code.
Share the room code. Your opponent joins instantly over WebSocket.
Both players see the same buggy function. The timer starts. Fix it — fast.
