Alteruna Global Cloud
Alteruna is your all-in-one cloud platform for building and running multiplayer games — powerful, accessible, and built to get you started fast.
Get up and running instantly with our free plan. When you're ready to scale, upgrading or downgrading is seamless, with no need to re-import packages on our site or in Unity.
All your game sessions run in the Alteruna Cloud, where hosting, operations, and auto-scaling are fully managed — so you can focus on building, not backend.
Whether you're developing premium PC titles for Steam, free-to-play mobile games, or cutting-edge XR experiences, Alteruna is the multiplayer solution built for your creative vision.
Alteruna On-Premises
Take full control of your multiplayer infrastructure with Alteruna’s self-hosting options. Studios can deploy the Alteruna relay server on-premise or in a private cloud, using their own infrastructure to meet security, compliance, or performance requirements.
All Alteruna registered plans support dedicated servers, enabling game sessions to run on standalone machines—whether in your data center or hosted by users, similar to community-hosted servers like Minecraft.
We also support peer-to-peer connections over LAN, where one player acts as the host and others join as clients — ideal for offline or local play scenarios.
Regardless of the setup, all server types seamlessly integrate with Alteruna’s licensing system and APIs, ensuring consistent management and functionality across deployments.
