Day 1
Immediate Productivity
Developers ship from day one. The familiar .NET ecosystem means no ramp-up and no new language to learn.
1 server
Eliminate VDI Costs
Retire Citrix, VMware, and Remote Desktop — a single server replaces the whole VDI stack.
Anywhere
Deploy Your Way
On-prem, cloud, or hybrid — even a Raspberry Pi. No vendor lock-in, ever.
AI-ready
A Platform for AI
A foundation for copilots, intelligent automation, and natural-language workflows.
