Unity Operating System

Unity Operating System (also known as Unified Operating System or UOS, ) is a Linux distribution developed by UnionTech (, Tǒngxìn) based on Deepin, which is based on Debian. It is used in China as part of a government initiative beginning in 2019 to replace foreign-made software such as Microsoft Windows with domestic products.

Development
Three versions are currently under development, a desktop for regular users (Deepin), another for enterprises (UOS) and a server version (UOS). A first beta version was released in 2019-12 and can be downloaded from the official website. A first stable version was released on 14 January 2020.

Support
The operating system is primarily aimed at the Chinese market and is intended to replace Microsoft Windows in the country by 2022,  also known as "3-5-2 policy". So far, the focus has therefore been primarily on in house hardware such as that from the semiconductor company Zhaoxin. The whole KX-6000 series is already supported by the desktop version as well as the KH-30000 series for server version.

It was reported on July 23, 2022 that the operating system could support HarmonyOS app file format, hap .app.

Broad support is planned, so platforms such as Loongson, Sunway or ARM are also to be supported.
