Reactor v1.1.2
Get started with Reactor
Install takes under a minute. The local server downloads automatically after the package is added.
New here? Reactor is a server-authoritative multiplayer engine for Unity that compresses your network traffic automatically, with no serialization code to write. In a controlled benchmark it moved 9.5x less transform data than Photon Fusion 2 and Netcode for GameObjects.
See what Reactor does →Before you start
You need Unity (2021.3 LTS, 2022.3 LTS, or 6.x) and the .NET 8 SDK installed. The local development server runs on .NET, so it will not start without the SDK.
Download the .NET 8 SDK →Open Unity Package Manager
In the Unity menu bar, go to Window → Package Manager. Click the + button in the top-left corner and select Add package from git URL…
New to the Package Manager? Unity's guide on installing a package from a Git URL walks through it.
