Hazel Engine is a 3D game engine developed by Studio Cherno and volunteer contributors. It originally grew out of the Game Engine series on YouTube. Officially positioned as a “simple-yet-powerful” interactive 3D development platform, it can be used to create and ship 3D games, interactive applications, and art projects. It has also been used for math/data visualization, education, and experimentation with real-time applications.
Based on publicly available information, Hazel leans toward low-level, modern graphics development. The engine is written in C++ and supports Windows and Linux. Its scripting layer uses C# .NET Core, offering a workflow that is broadly similar to scripting in Unity. On the rendering side, it uses Vulkan and is designed around an API-agnostic renderer, with a multithreaded runtime and a physically based Forward+ HDR renderer. The official roadmap also mentions exploration of path tracing, offline rendering, and cinematic tools, suggesting that its ambitions extend beyond games into both real-time and offline graphics applications.
At present, Hazel is not fully open to the public. Access to the full development repository and community requires a Patreon subscription at the Supporter III tier or above, priced at $10/month, with access retained while the membership remains active. The official plan is to release free prebuilt binaries in the future so users can create and publish Hazel games and applications for free; however, the source code and development branches will continue to be provided through Patreon. Some components are already open source, such as the C# scripting engine Coral.
Hazel’s strengths lie in its clear technical direction, making it appealing to developers interested in C++, Vulkan, rendering architecture, and engine implementation. The C# scripting layer also helps lower the barrier for gameplay logic development. The project has articles, videos, documentation, and community entry points, providing a relatively rich set of learning resources. Its limitations are that full access currently sits behind a subscription, and the public materials do not fully clarify details around the editor, asset pipeline, cross-platform publishing, commercial licensing, or long-term support. The only clearly stated supported platforms are Windows and Linux.
Hazel is better suited to indie game developers, graphics programmers, engine learners, education projects, and visualization work than to teams that need a mature commercial ecosystem, an asset store, and a stable release toolchain. Access from China cannot be determined from the available text alone; Patreon payments and access may be uncertain from within mainland China. If you need a more mature alternative, consider comparing it with Unity, Unreal Engine, Godot, O3DE, or Stride.
