Deploy and Host Bun WebSocket Game Server with Railway

Room-based multiplayer WebSocket relay server using msgpack binary protocol. 5-8x faster than Node.js ws — same protocol, same clients. Bun-native.

About Hosting Bun WebSocket Game Server

This template deploys a stateless WebSocket relay server built on Bun's native WebSocket API. Clients connect via ws:///ws/, get assigned a player ID, and all messages are relayed to peers in the same room using msgpack encoding. Uses Bun's built-in pub/sub for efficient room broadcasting, zero-allocation per-connection state via ws.data, and includes per-client rate limiting, keepalive, origin allowlist, and /health + /metrics endpoints.

Common Use Cases

Multiplayer browser games (2D/3D position sync, input relay)
Collaborative real-time apps (whiteboard, document editing)
Chat rooms with binary protocol efficiency
IoT dashboards with low-latency pub/sub
High-throughput relay where Node.js ws becomes a bottleneck

Dependencies

Bun 1.x (runtime — includes native WebSocket server)
@msgpack/msgpack (binary serialization)
