Multiplayer Framework for Node.js.
View documentation

Colyseus is an Authoritative Multiplayer Framework for Node.js, with clients available for the Web, Unity3d, Defold, Haxe, and Cocos2d-X. (See official clients)

The project focuses on providing synchronizable data structures for realtime and turn-based games, matchmaking, and ease of usage both on the server-side and client-side.

The mission of the framework is to be a standard netcode & matchmaking solution for any kind of project you can think of!

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.
