Netcode for GameObjects (Netcode) is a high-level networking library built for Unity for you to abstract networking logic. It enables you to send GameObjects and world data across a networking session to multiplayer players at once. With Netcode, you can focus on building your game instead of low-level protocols and networking frameworks.

Refer to the console's internal documentation for more information. This content is typically protected by NDA.
Netcode does not support the WebGL platform because it does not allow access to IP Sockets.
There are third party transports provided by the community that may enable you to use Netcode on WebGL platforms. A list of these transports are found here.
Use with caution:
- You may encounter bugs and issues while using Netcode on WebGL, and we won't prioritize fixing those issues.
- The server or host can't be a WebGL client, but a Desktop or Mobile build.
- You may experience increased latency and jitter because of the TCP protocol used by WebSockets.
This is free under the permissive MIT Licenses by Unity and the Netcode collaborators. Netcode is open source with no attached costs or limitations, so you can develop features alongside Unity.
