Could you build this?
Partial The multiplayer matchmaking and front-end code editor are easily vibe-coded, but building a safe, isolated, multi-language code execution engine with strict resource quotas and edge-case evaluation is non-trivial.
What it would actually take: The system requires a WebSocket backend (Node.js/Go) for matchmaking, code synchronization, and live clocks, connected to an isolated remote code execution sandbox like Judge0, gVisor, or Firecracker microVMs. The hard technical hurdle is securing the runner against fork bombs, memory exhaustion, network breakout, and malicious system calls while reliably measuring runtime down to the millisecond. It requires backend systems programming and container security expertise.
