Delta developer platform

Realtime multiplayer

Room-based WebSocket transport for presence, inputs, state, and game events.

Connect and join

Connect to /ws through the same Nginx endpoint. Clients join sanitized room IDs and messages are capped at 32 KiB.

const socket = new WebSocket("wss://your-domain/ws");
socket.send(JSON.stringify({ type: "join", roomId: "arena-42" }));

Authority

The built-in relay is appropriate for prototypes and cooperative games. Ranked movement, inventory, fire rate, and economy need authoritative server validation.
