In short, Forge Networking is a free and open source multiplayer game (multi-user) networking system that has a very good integration with the Unity game engine. You wanna make a multiplayer game or real time multi-user application? This is the library for you.

Welcome to the most innovative networking solution (which works with the Unity game engine). Forge's network bandwidth is unbeatable, its performance outclasses other solutions, its flexibility is in a league of its own, and, as always, it has no CCU limits whatsoever. Forge Networking is an open source networking solution built in C#. It is completely multi-threaded and was designed to work both inside and outside of the Unity Game Engine but mainly in conjunction with Unity. To get started, check out the links listed below in this readme.


  • Unity multiplayer games/applications
  • Unity independent applications
  • User hosted servers
  • Run servers on Windows, OSX, Raspberry Pi, and/or Linux
  • Developer hosted servers
  • MMO, RTS, FPS, MOBA, you name it, Forge does it
  • Master Servers, NAT Hole punching, Web Servers, Cache servers, all the servers!
  • Server to server communication, yup
  • Spin up servers on demand, check
  • Tons of other stuff that I won't list otherwise I will go on forever, yes indeed

If you can name it, Forge most likely can do it :), it is built on some basic principles which makes any idea a possibility.


Forge Networking is a networking solution built with the Unity game engine in mind. However, this is actually the 2nd version of Forge so it has some interesting properties. The first original Forge (classic) was built directly inside of Unity and was very tightly integrated with Unity. Once we learned everything we could from that version we opened up a blank Visual Studio project and began work on Forge Networking Remastered. Forge Networking Remastered was completely developed independently of Unity, it was tested and debugged in a C# project. Once it was working, we added Unity integration. This means that you can easily create native C# applications which run on Forge to support your games and applications such as Relay servers, NAT hole punching servers, chat servers, master servers, cache servers, websocket servers, you name it! Forge was developed in a way that makes it easy for you to serialize data in any way that you want. This allows you to make your project as secure as you want or as fast as you need.
