Why UnionTech UOS Is Leading China’s Domestic Linux Desktop OS Market

1. Overview of Domestic Linux Desktop OSes

UnionTech UOS

UnionTech UOS, developed by UnionTech Software, is based on the Linux kernel (some versions inherit from Deepin’s Debian base). It targets both desktop and server scenarios. As of the end of 2023, its installations have exceeded 6 million units, with a notable share in government, education, and enterprise markets. It supports x86, ARM (e.g., Kunpeng, Feiteng) and RISC‑V architectures, covering laptops, desktops, and all‑in‑one PCs. Its software ecosystem is built through a self‑managed app store that integrates mainstream applications such as QQ, WeChat, and WPS, and it also uses Wine to run some Windows software. In 2024, UnionTech released “UOS AI”, embedding AI capabilities to further improve user experience.

Kylin OS (Galaxy Kylin)

Kylin OS, created by Kylin Software, is also Linux‑kernel based and emphasizes high security and stability. Its desktop edition is oriented toward government and military use, supporting x86, ARM and domestic CPUs such as Loongson and Feiteng. However, its ecosystem focuses more on professional users and offers fewer software packages than UnionTech UOS. Recent efforts have been made to develop a community edition, but desktop usability still requires improvement.

Deepin

Deepin, developed by the Wuhan Deepin team, is one of the technical origins of UnionTech UOS. It is known for its attractive interface and strong usability. Deepin is an open‑source community project supporting x86 and some ARM platforms, featuring the Deepin Desktop Environment (DDE) and a rich app store. Because it is community‑driven, its commercialisation and large‑scale hardware support are relatively limited.

openKylin

openKylin, released in 2023, is an open‑source desktop OS led by Kylin Software together with multiple enterprises and communities. It stresses openness and collaborative ecosystem building, supporting x86 and domestic CPUs. Nevertheless, its application ecosystem and user experience are still in early stages, making it difficult to compete with mature systems in the short term.

2. UnionTech UOS’s Strengths and Comparison

In terms of growth momentum, UnionTech UOS is clearly the leader among Chinese Linux desktop OSes. Its installation volume and market share far exceed rivals, especially in government procurement (e.g., 300,000 units ordered by China Post) and education (e.g., 20,000 units for Beijing’s Fengtai District Education Committee). Its hardware compatibility is extensive, covering mainstream devices and deep collaborations with domestic CPU vendors, while its ecosystem is more grounded, satisfying everyday office and entertainment needs.

Compared with Kylin OS, which leans toward server and high‑security scenarios, UnionTech UOS offers broader desktop usability. Deepin possesses strong technical foundations but lacks UnionTech’s commercial push. openKylin is still exploratory.

UnionTech UOS also invests heavily in user experience. Dual‑mode “fashion” and “efficiency” desktops, voice assistants, and AI integration bring usability comparable to Windows and macOS, with some commentators calling it “the most usable domestic operating system today”. This shift from merely “available” to “pleasant to use” underpins its bid to become the strongest Linux desktop in China.

3. Remaining Challenges

Ecosystem completeness : Although UnionTech UOS supports a large amount of hardware and software, its ecosystem size is still far behind Windows. The absence of professional tools such as Adobe suite and CAD software may deter certain users.

User habit migration : Users accustomed to Windows must adapt to a new interface and workflow. UnionTech UOS lowers the entry barrier, but widespread adoption still requires time.

Technical innovation and competition : International Linux distributions (e.g., Ubuntu, Fedora) and the AI‑driven evolution of Windows create pressure. UnionTech must maintain rapid iteration to avoid falling behind.

Market and policy balance : Heavy reliance on policy‑driven government procurement is a double‑edged sword. If policy support weakens, UnionTech will need to prove competitiveness in the civilian market.

4. Conclusion

Overall, UnionTech UOS leverages its installation volume, extensive hardware support, and enhanced user experience to lead the domestic Linux desktop market, with potential to become the top contender. However, to truly challenge Windows’ dominance, it must close ecosystem gaps and shift user habits. Continued AI‑enabled innovation and collaborative ecosystem building could open a new frontier for Chinese operating systems.
