UnionTech (Tongxin Software Technology Co., Ltd., Chinese: 统信软件) is a prominent Chinese software enterprise specializing in the development of commercial operating systems, system-level architecture, and foundational software infrastructure. Founded in 2019 through a government-supported consolidation of veteran domestic Linux development teams?most notably Deepin Technology?UnionTech is headquartered in Beijing, China, with major research, development, and support hubs located across Wuhan, Shanghai, and Guangzhou.
The primary mission of UnionTech is to architect a highly secure, independent, and self-reliant computing ecosystem. Operating as a core pillar of China's technological localization and national "Information Technology Application Innovation" (Xinchuang) initiatives, the company focuses on replacing foreign-made operating systems (such as Microsoft Windows and macOS) within government bodies, military institutions, financial services, state-owned enterprises, and critical national infrastructure. To achieve this, UnionTech maintains a unique software duality: managing the community-driven, open-source deepin Linux distribution while engineering and licensing its proprietary enterprise flagship, Unity Operating System (UOS), also known as Tongxin UOS.
Core Product Portfolio: Operating Systems
UnionTech?s product matrix scales across desktop, server, and specialized industrial hardware, using a unified Linux kernel backbone optimized for broad architectural diversity.
1. Unity Operating System (UOS) Desktop Edition
The commercial flagship for client-side computing, UOS Desktop Edition is built as a highly stable, enterprise-grade Linux distribution derived from Debian. It targets a modern consumer look and feel while enforcing rigorous access controls and corporate audit frameworks.
Deepin Desktop Environment (DDE): UOS utilizes the proprietary, highly polished DDE graphical interface. Crafted natively with a Qt and QML framework, DDE provides an intuitive, fluid visual experience featuring advanced window management, skeuomorphic styling elements, and customizable workflow layouts designed to mirror familiar consumer desktop experiences.
Broad Architecture Compatibility: A major differentiator for UOS is its native compatibility with both x86-64 legacy processors and a vast array of domestic Chinese processor architectures. The operating system provides tailored builds optimized for Loongson (LoongArch), Feiteng (ARM), Kunpeng (ARM), Zhaoxin (x86), and H光 (MIPS) hardware setups.
Linyaps Framework: A proprietary, universal software encapsulation framework engineered by UnionTech. Linyaps decouples applications from underlying system library dependencies, resolving software fragmentation and allowing cross-distribution deployment within the ecosystem.
2. Unity Operating System (UOS) Server Edition
Engineered to power complex corporate datacenters, cloud environments, and high-concurrency computing clusters, UOS Server Edition isolates its core capabilities around performance scaling, virtualization efficiency, and long-term stability.
Enterprise Cloud Support: Integrates seamlessly with domestic cloud desktop infrastructures and major virtualization platforms, providing low-latency storage pooling and advanced networking fabrics.
High Reliability & Performance Tuning: Features specialized kernel-level optimizations designed to run continuous database workflows, containerized cloud applications, and hardware-accelerated processing architectures.
3. Unity Operating System (UOS) Embedded Edition
A lightweight, modular variant designed explicitly for Internet of Things (IoT) nodes, financial ATMs, edge gateways, industrial control systems, and automated public kiosk terminals. It offers a minimal hardware footprint paired with rapid boot capabilities and isolated read-only root directories.
Native Artificial Intelligence: The UOS AI Ecosystem
To address the modern shift toward hardware-accelerated machine learning, UnionTech has deeply integrated systemic AI frameworks into its operating layers via the UOS AI suite. In its latest iterations, AI is treated as a fundamental subsystem rather than an ancillary application layer:
Dual-Mode Engine Architecture: UOS AI provides a flexible operational model. It can connect via secure APIs to external cloud-based large language models (such as DeepSeek, Baidu Qianfan, or iFlytek Spark). Alternatively, for secure or offline operations, it interfaces natively with the localized "UnionTech YouRong Large Model", keeping data vector processing localized on user devices to guarantee privacy.
Grand Search Framework: Implements system-level intelligent indexing utilizing a local vector database. Users can execute fuzzy natural language searches across all local documents (e.g., searching for "financial summary" uncovers untagged spreadsheets or document sections containing implied context, bypassing rigid filename matches).
System-Level Interaction: Enables hands-free desktop orchestration. Users can feed natural language commands to the desktop interface via text or voice to execute localized configurations, such as toggling dark mode configurations, modifying system display scales, adjusting hardware permissions, or scheduling calendar notifications.
Agent Store: A dedicated distribution repository within the OS where enterprise operators can download specialized AI tools and task-specific automation agents tailored to unique industry verticals.
Security Engineering and Compliance Guardrails
As a cornerstone of security-sensitive deployments, UOS implements robust hardware-to-software security frameworks designed to insulate infrastructure from malicious tampering:
Read-Only Core Protection (Solid Engine): Forcibly mounts foundational operating directories (such as /usr/bin) under a read-only permissions architecture. This effectively prevents automated malware payloads or accidental administrative overrides from modifying the core system files.
Second-Level Automated Snapshots: The operating system generates automated backup snapshots directly before running system-wide software upgrades, facilitating immediate, worry-free rollbacks if an integration failure occurs.
Worry-Free Restore Environment: Designed explicitly for public terminals, educational computer labs, and exhibition environments. This self-cleaning engine clears all cached browser footprints, runtime configurations, and user modifications instantly upon a system reboot, matching stringent corporate data sanitation standards.
