Multiplayer Game Server for Node.js.
View documentation

Colyseus is a Authoritative Multiplayer Game Server for Node.js. It allows you to focus on your gameplay instead of bothering about networking.

The mission of this framework is to be the easiest solution for creating your own multiplayer games in JavaScript.

This framework is fairly new and is being evolved constantly. You're encouraged to take a look on some games being developed with it and make your own!

What Colyseus provides to you:

WebSocket-based communication
Simple API in the server-side and client-side.
Automatic state synchronization between server and client.
Matchmaking clients into game sessions
Scale vertically or horizontally

What Colyseus won't provide:

Game Engine: Colyseus is agnostic of the engine you're using. Need Physics? Add your own logic / package.
Database: It's up to you to configure and select which database you'd like to use.

See roadmap for our future plans.
