Question: Is Unity open source?

Answer

No, Unity is not open source. Unity is a proprietary game development engine developed by Unity Technologies. It offers a free personal edition with certain limitations in terms of revenue generation and feature sets, as well as various paid subscription models that unlock more features and capabilities.

Unity does provide the Unity Editor for various platforms, along with many of its components, under a proprietary license. They have also released portions of their platform, such as the C# part of the Unity engine and editor, known as the Unity C# reference source code. This allows developers to view and learn from the internals of the Unity Editor and engine without granting permissions to modify or distribute the Unity technology itself.

For developers seeking an open-source alternative to Unity, there are other engines like Godot, which is fully open source under the MIT license and allows for more freedom in modifying and distributing the engine's code.

While Unity itself is not open source, it supports an open ecosystem by enabling developers to create and share their own tools, assets, and plugins through the Unity Asset Store. Additionally, Unity has been known to collaborate with the open-source community on various projects and initiatives, contributing to the broader development landscape while maintaining its proprietary core.
