About xsubi

Self-hosted cloud infrastructure. Your hardware. Your rules.

Not a cloud reseller. Not a managed service. Real bare metal — owned, operated, and transparent.

Mission

xsubi provides VM hosting and game server hosting on hardware we own and operate directly. KVM on Ubuntu Linux (libvirt) and Hyper-V on Windows Server 2022 DC — no cloud intermediary, no vendor lock-in, no opaque infrastructure between you and your machines.

The differentiator is control. You get full transparency into the stack your workload runs on, predictable pricing without surprise egress fees, and an operator who actually owns the hardware rather than reselling capacity from AWS, Azure, or GCP.

Ecosystem

The xsubi platform spans multiple services — each purpose-built, each cross-linked.

Customer Portal

VM and game server management — provision, monitor, and control your instances from a unified Blazor dashboard.
