Add Multiplayer Without Network Coding

With Alteruna, Unity creators can easily add multiplayer to their games without needing programming skills. Just drag and drop to sync changes, stats, voice, and more in the editor. Set everything up to meet your needs and concentrate on developing your game's main features while we manage the networking.

Adaptable Network Structure for Your Game Requirements

Alteruna Multiplayer provides a flexible client-server system for your game. With Shared State, the main room controls the game's status while clients manage their own objects. We also allow Peer-to-Peer connections over LAN, enabling any client to function as both client and server. This adaptability guarantees smooth multiplayer experiences suited to your game's specific needs.

Superior Speed for Seamless Playing

Alteruna’s efficient transport protocols, using both UDP and TCP, ensure fast data transfer between clients. By reducing data traffic, we improve your game’s performance, making multiplayer experiences smoother, more responsive, with less lag and quicker interactions.

Easy Cross-Platform Support for Any Game

Developing for different platforms is easy with the Alteruna Unity SDK. Just select your platform in the editor and build your game for mobile, PC, web, consoles, or XR. Alteruna Multiplayer supports all these options, so your game can reach players everywhere.
