From Replacement to Leadership: The Golden Era of Chinese Open‑Source Linux

1. Core Analysis of the Five Open‑Source Linux Communities

deepin (深度) – The Desktop Ecology Pioneer

Core Positioning: The longest‑running domestic desktop community (est. 2008) led by Tongxin Software, emphasizing "extreme beauty and ease of use + cross‑industry deployment" and serving as the benchmark for Chinese desktop Linux.

Killer Feature: UI design comparable to Windows/macOS, 1,200+ software adaptations with over 160 medical vendors, AI agents automating approvals in government and public security, dramatically improving office efficiency.

Ecosystem Scale: Tens of millions of global developers follow the community edition; commercial edition UOS serves more than 100 top hospitals; over 400 CentOS systems migrated with 100% smooth transition; leading desktop localization rate.

OpenAnolis (龙蜥) – The Best CentOS Alternative for Cloud‑Native

Core Positioning: A neutral, open server‑OS root community focused on cloud‑native scenarios and seamless CentOS migration, co‑led by Alibaba Cloud with 24 council members, free of single‑vendor lock‑in.

Killer Feature: 100% CentOS compatibility, centos2anolis one‑click migration tool with zero conversion cost; ANCK kernel optimized for cloud workloads, delivering 40% performance boost and up to ten‑year lifecycle (e.g., Anolis OS 23 supported until 2033).

Ecosystem Scale: Over 10 million installations, full support for FeiTeng, Loongson, Kunpeng chips; 800+ industry partners co‑building; unified kernel kAPI with openEuler and OpenCloudOS to avoid fragmentation.

openEuler (欧拉) – The Collaboration King for Full‑Scene Digital Infrastructure

Core Positioning: A Huawei‑led root community covering server, cloud, edge and embedded scenarios, aiming to break ecosystem fragmentation and achieve "one chip, one system, one ecosystem".

Killer Feature: Multi‑architecture support (x86/ARM/RISC‑V/LoongArch), compatibility with 20 000+ enterprise applications, 24.03 LTS built on Linux 6.1 kernel, AI‑compute co‑ordination and large‑memory management optimizations for seamless cloud‑edge‑terminal deployment.

Ecosystem Scale: Over 1 800 member units, 20 000+ global contributors, more than 680 000 installations; spawns commercial variants such as Kylin and Tongxin, widely used in finance, telecom, energy and transportation.

OpenCloudOS (鸥栖) – The AI‑Compute Base for Full‑Link Autonomy

Core Positioning: A Tencent‑led cloud‑native server OS community promoting "L1‑L2‑L3 full‑link self‑evolution" from kernel to applications, eliminating external dependencies and focusing on AI‑compute scenario optimization.

Killer Feature: Full compatibility with NVIDIA, Ascend and other AI accelerators, providing 20 ready‑to‑run AI‑framework images, reducing AI deployment cost; validated in tens of millions of production nodes, cutting fault‑response time to minutes in financial‑trust scenarios.

Ecosystem Scale: 31 council members, 500+ ecosystem partners, over 20 million nodes installed, leading domestic cloud‑native server OS; supports domestic chips (FeiTeng, HaiGuang, Loongson) and spawns commercial versions like Tencent Penglai and Donghua NTOS.

OpenKylin (开放麒麟) – The Desktop Security Benchmark for Trusted Computing

Core Positioning: Hosted by the OpenAtom Foundation, led by Kylin Software, targeting government, education and finance trust‑computing scenarios with "secure controllable + intelligent interaction".

Killer Feature: Built‑in Kylin AI assistant supporting Wenxin Yiyan and offline large models for office AI empowerment; "PanStone" architecture ensures system security against network attacks; full compatibility with Windows/Android apps; over 24 million deployments.

Ecosystem Scale: 2.27 million users, 20 000+ developers, adaptation to more than 20 RISC‑V hardware platforms, driving the world’s first RISC‑V notebook with pre‑installed Linux; products deployed in 188 countries and regions.

2. Comparative Overview of the Five Communities

The communities differ in core scenarios, architecture support, lifecycle, and strengths. For example, deepin focuses on desktop usability, OpenAnolis on CentOS compatibility and cloud performance, openEuler on full‑scene coverage, OpenCloudOS on AI‑compute foundations, and OpenKylin on secure desktop and trusted‑computing.

3. Three Development Trends for Domestic Open‑Source Linux

1) Ecosystem Co‑Construction Replaces Fragmented Efforts

OpenAnolis, openEuler and OpenCloudOS have already unified kernel kAPI and configuration standards, preventing duplicate work and fostering "technology collaboration + complementary advantages". Future work will deepen standards for hardware‑software adaptation in trust‑computing, AI and cloud‑native, moving Linux from "usable" to "excellent".

2) Deep Fusion of Cloud, AI and Industry

Domestic Linux is evolving from a pure OS layer to an "intelligent platform" embedded in core industry workloads: OpenAnolis optimizes performance for cloud‑native AI, OpenCloudOS builds a dedicated AI‑compute base, while OpenKylin and deepin integrate AI assistants into desktop workflows, turning the OS into a digital‑transformation engine.

3) High Domestic Substitution Rates in Key Sectors

By 2025, operating‑system substitution rates in government, finance, telecom, energy and defense are expected to exceed 85%, making these sectors the main battlefield for Chinese Linux. Mature community technologies will enable full‑link autonomy and reduce reliance on foreign systems, granting China greater influence in the global open‑source ecosystem.

4. Selection Recommendations

If you need a CentOS replacement, prioritize OpenAnolis (龙蜥).

For full‑scene deployments, choose openEuler (欧拉).

When focusing on AI compute, recommend OpenCloudOS (鸥栖).

For desktop trust‑computing, OpenKylin (开放麒麟) or deepin (深度) are both suitable.
