Backed by Alibaba Cloud, the company's open-source virtualization platform ZSVirt now reaches users in 145 countries — and its newly open-sourced GPUWorks brings lightweight MaaS to enterprises worldwide.
SHANGHAI, Nov. 11, 2026 — ZStack, a cloud and AI infrastructure software provider backed by Alibaba Cloud, held a groundbreaking ceremony for its new Shanghai headquarters on Tuesday. The project marks the company's preparation for its next decade of growth — one defined by open source and AI infrastructure rather than office space alone.

"Open source has become the fastest way for enterprise infrastructure software to earn global trust," said Frank Zhang, founder and CEO of ZStack, at the ceremony. "The new building is where we will build the next ten years — but what we're really building is a global, open ecosystem around cloud and AI infrastructure."

From VMware alternative to global open-source adoption
ZStack's momentum has been driven by ZSVirt, its enterprise-grade virtualization platform open-sourced under GPL 3.0 in August 2026. Derived from a commercial engine proven in more than 1,000 production environments, ZSVirt ships with ZMigrate, a free migration tool compatible with VMware vSphere 5.x–8.x — arriving just as enterprises worldwide reassess their virtualization stack amid Broadcom's licensing changes.
Since its release, ZSVirt has been downloaded and deployed by users in 145 countries and regions, making it one of the fastest-adopted open-source virtualization platforms to emerge this year.
GPUWorks: lightweight MaaS, open-sourced
Extending the same open-source strategy to AI, ZStack recently open-sourced GPUWorks, a lightweight Model-as-a-Service (MaaS) platform that lets enterprises deploy, serve and manage AI models on their own GPU infrastructure — without the operational weight of a full AI stack. GPUWorks complements ZStack's commercial AIOS intelligent computing platform and Zentrix enterprise AI gateway, giving organizations a gradual, open on-ramp to private AI.
"Enterprises don't adopt AI by replacing everything they have," Zhang said. "They adopt it by building on infrastructure they already trust. Open source is how we earn that trust globally."
