Browser-Based Local Multiplayer Racing Game with Phone Controllers

Steer It is a browser-based local multiplayer party racing game. The host opens it on a laptop or TV, players scan a QR code with their phones, and the phone becomes a tilt steering wheel. No app installs, no accounts, no gamepads. Connection is peer-to-peer over WebRTC with a Cloudflare TURN relay for restrictive networks.

Built solo over five months of full-time work. The physics is custom — a per-wheel simulation model with deterministic golden tests, so replays reproduce exactly. It is not a reskinned arcade controller.

Honest position on money: this is pre-revenue. Premium gating is live and works end to end — one car is premium-locked and a review-for-premium flow runs — but nothing has converted yet. The mechanism is proven; what is missing is volume and a monetisation push.

The engineering is done. The commercial side is entirely open.
