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 Cocos. (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!

Key features:

• WebSocket-based communication
• Simple API in the server-side and client-side.
• Automatic state synchronization from server-to-client (delta compressed)
• Matchmaking clients into game rooms/sessions
• Scale vertically or horizontally

See roadmap for our future plans.
