Unity is a globally adopted game engine that powers countless independent developers, small studios, and commercial projects. However, since Unity Technologies transferred its China-region operations to a local joint venture (Unity China, also known as the “Tuanjie Engine”) in 2024, users in mainland China have gradually lost access to the international version of Unity. As of now, Unity Hub no longer allows Chinese users to download the international Editor — only Unity China’s localized version is accessible.
It’s crucial to understand that the version of Unity distributed by Unity China — currently branded as “Tuanjie Engine” — is not simply a localized variant of the international Unity editor, it is in fact a separate, incompatible product:
- Projects created or opened in Tuanjie Engine cannot be reopened in standard Unity editors.
- It breaks compatibility with many official tools, services, and plugins available through Unity’s global ecosystem.
This is not a regional skin or language pack — it is a divergent build that splits Unity’s technical and community ecosystem. Developers using Tuanjie Engine are effectively locked into a separate track, isolated from global tools, documentation, tutorials, and collaborative workflows.
This distinction is fundamental. What’s being enforced in China is not merely a regional deployment of Unity, but a structurally fragmented product under the same brand.
We express our clear objection to this. We do not oppose the existence or promotion of Unity China, but we strongly oppose the forced abandonment of the international version through technical restrictions. Many ongoing projects have been built on international Unity versions, and switching versions entails significant risk and cost. Moreover, a number of developers have legitimate concerns regarding the long-term maintenance and consistency of the Unity China version. Taking away user choice will only erode trust in the Unity platform.
We call on Unity Technologies to take this issue seriously and to strengthen oversight of Unity China, in order to safeguard the fundamental right of developers to choose the tools they rely on.
Localized operations should be about improving service quality, adapting to local infrastructure, and enhancing accessibility — not about replacing and locking out the product developers are already using. If the Unity China version offers genuine advantages, it will naturally be adopted by the community. But currently, instead of building user trust through better performance or services, Unity China’s strategy relies on CDN restrictions, Unity Hub source redirection, and account segregation to push users away from the international version.
This is not a sustainable approach to product adoption, nor is it a respectful way to treat a developer community.
We understand that the business environment in China presents unique challenges that may require technical and operational adjustments. But such adjustments should not come at the cost of fragmenting the core version structure of Unity. It is fully possible for Unity to provide a “China version” that is functionally identical to the international version, with the same version numbers, features, and usage logic.
Currently, however, the Unity China version differs from the international version in key ways: versioning, available services, plugin compatibility, documentation, and more. Once the toolchain becomes fragmented, cross-team collaboration, version management, plugin integration, educational alignment, and multi-platform deployment are all affected. This is not just a short-term inconvenience — it actively undermines the developer ecosystem Unity has spent over a decade cultivating in China.
Therefore, we respectfully request that Unity Technologies:
- Restore access for users in mainland China to the international Unity website and Unity Hub’s official version download;
- Allow users to freely choose between Unity China and the international version, without IP restrictions or forced redirection;
- Or alternatively, provide a “China Edition” that is fully synchronized with the international version, in functionality and release cadence.
We believe that:
Optimized experience may attract users — but freedom of choice is what they fundamentally deserve.
Unity’s global value comes from its consistent tooling, open ecosystem, and developer trust. We hope the company can remain true to these principles, even as it adapts to local markets. Short-term control measures must not come at the expense of long-term developer trust and product integrity.
拒绝强迫：反对 Unity 在中国强制推广“团结引擎”
Unity 是全球广泛使用的游戏引擎，支撑着无数独立开发者、中小团队与商业项目。然而自 2024 年 Unity Technologies 将中国区交由合资公司 Unity China（团结引擎）运营以来，中国大陆用户逐渐失去了访问国际版 Unity 的自由。截至目前，Unity Hub 已无法正常下载国际版编辑器，用户只能使用由 Unity China 推出的“团结引擎”。
必须明确一点：由 Unity 中国发行的版本，目前被称为 “团结引擎”，并不仅仅是国际版 Unity 的本地化变体，它实际上是一个独立的、不兼容的产品：
- 使用团结引擎创建或打开的项目，无法再用标准的国际版 Unity 编辑器打开。
- 它与许多 Unity 官方工具、服务及插件之间存在兼容性问题。
这不是一个区域皮肤或语言包，而是一个架构上分裂的构建版本，正在破坏 Unity 原本统一的技术与社区生态。使用团结引擎的开发者，实际上被锁定在一个独立的开发路径中，与全球的工具、文档、教程和协作流程相隔离。
这个区别是根本性的。中国目前被强制推行的，不是一个地区部署的 Unity，而是一个以同一品牌发行的、结构上割裂的产品。
我们对此表示明确反对。我们并不反对团结引擎的存在或推广，但我们反对以技术封锁的方式强制用户放弃国际版。许多开发者的项目长期基于国际版构建，切换版本带来不可忽视的风险和成本。同时，也有不少开发者对团结引擎的长期维护质量与功能完整性持保留态度。剥夺用户选择权，只会破坏开发者对 Unity 平台的信任。
我们呼吁 Unity Technologies 正视这一问题，并加强对 Unity China 的治理，以确保用户自由选择的权利不被侵蚀。
本地化运营的目标应是改善服务体验、适配技术环境、优化访问效率，而不是用另一个版本来取代并封锁原有产品。如果团结引擎在功能与服务上具备优势，它自然会赢得市场认可。但当前的推广策略，并未依靠体验提升来获得用户信任，而是通过CDN 限制、Hub 源重定向、账号系统割裂等方式，迫使用户放弃他们原本正在使用的国际版工具链。
这不是一个可持续的产品策略，也不符合一个全球平台对开发者应有的尊重。
我们理解，中国市场环境的特殊性为 Unity 的运营带来了一定挑战，这可能促使公司在技术架构与部署方式上进行调整。但这种调整不应以版本割裂为代价。Unity 完全可以提供一个与国际版功能、版本、使用逻辑完全一致的“中国版本”，以满足当前需求，同时保留工具链的连续性与生态的统一性。
目前团结引擎与国际版在版本号、功能边界、文档体系等方面存在明显差异。一旦工具链被人为分裂，跨团队协作、插件适配、教学资源使用、项目迁移等环节都将面临额外障碍。这不仅对正在开发产品的专业团队构成冲击，也对初学者与教育者造成严重干扰。Unity 长期以来在中国建立的开发者生态，正在因这场不必要的封闭策略而遭到削弱。
我们郑重请求 Unity Technologies：
- 恢复中国用户访问 Unity 国际官网与 Hub 下载国际版编辑器的能力；
- 允许用户自主选择使用国际版或团结引擎，而非通过 IP 限制与绑定策略强行切换；
- 或者，在中国提供一个与国际版功能一致、同步更新的“官方中国版本”，避免版本割裂。
我们坚信：
体验优化可以赢得用户，但自由选择是用户的基本权利。
Unity 的价值来源于其全球一致的工具生态与开发者信任。希望贵公司在面临转型与本地适配时，能够坚持这份初心，不以短期控制手段牺牲长期生态基础。
