Build multiplayer games with Unity Netcode
Netcode solutions for casual co-op
Target casual co-op multiplayer games with the Netcode for GameObjects package. Synchronize scenes and GameObjects data across multiple clients and platforms with either client- or server-authoritative models. Unity helps you optimize your multiplayer games with tools to profile the network, both in Play Mode and at runtime.
Relay, from Unity Gaming Services, is a cost-effective peer-to-peer companion service to scale playtests and build a multiplayer game without having to invest in dedicated hosting.
Netcode solutions for competitive action
Target competitive action multiplayer games with the Netcode for Entities package based on ECS, built for performance and scalability. Build ambitious server-authoritative gameplay featuring prediction, interpolation, and lag compensation.
Manage the costs with a dedicated server build target that can automatically strip assets. Deploy it with Multiplay Hosting from Unity Gaming Services, a streamlined approach to maintaining resiliency and scalability in your gaming infrastructure, so you can focus on providing the best experience to your players.
Level up your game with Unity Gaming Services
Build your small-scale cooperative game with Netcode for GameObjects and connect your players with Relay and Lobby.
Plus, access more Unity solutions available to build, manage, and grow your game – battle-tested by the biggest names in gaming.
Get fine-grain control of the transport layer
Unity Transport Package is a netcode-agnostic library that provides a low-level network layer focused on performance and reliability – a modern, secure, and portable transport library that extends the conventional UDP with advanced features such as support for the Unity Relay service, UnityTLS, and pipelines among others.
Both Netcode for GameObjects and Netcode for Entities rely by default on UTP as a transport. However, developers looking to keep fine-grain control over the network can use UTP as a standalone library.
