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!
## Why developers choose Colyseus:
- ⚡️ **Real-time state sync that just works** → Define your state on the server and it automatically synchronizes to all clients, delta-compressed and binary-encoded.
- ⚔️ **Built-in matchmaking** → Room-based architecture with filtering, queuing, and reconnection support out of the box.
- 📈 **Scalable** → Go from 10 to 10,000+ CCU by scaling vertically or horizontally with Redis and load balancers.
- 🛡️ **Cheat-proof by design** → Authoritative server model ensures game logic runs on the server, not the client.
- 🛠️ **Use the tools you already know** → Built on Node.js and TypeScript with a simple, familiar API on both server and client.
- 💙 **Free forever** → MIT licensed, even for commercial games.
See [public roadmap](https://docs.colyseus.io/roadmap) for version 1.0.
# 🚀 Quickstart
