Who Uses Editor Foundations

We encourage everyone who authors experiences for the Unity Editor to take advantage of the Editor Foundations Design System©, such as technical and non technical creators, engineers, designers, product managers and any one who wants to avoid duplication of efforts and save on production time.

The aim of Editor Foundations is to improve the Unity user experience by making the Editor UI more consistent, coherent, and easier to use by:

  • defining best practices for the UI design of the Editor and extensions
  • giving clear design rationale so users can make well-informed decisions when building UI
  • providing up-to-date documentation for the latest Unity LTS release
  • creating a virtuous feedback loop that allows users to suggest fixes and improvements to both the Editor and the Editor Foundations Design System

Editor UI Frameworks

The Unity Editor supports two user interface (UI) authoring frameworks;

Unity recommends you to use UI Toolkit for your new UI development projects.
However, Unity UI (uGUI) and IMGUI are appropriate for certain use cases, and are required to support deprecated projects. For more information, see the Comparison of UI systems in Unity.

Editor Releases

Currently, the content covered in Editor Foundations are targeted for LTS Release 2022.3.

Editor Foundations largely supports the latest Long Term Support (LTS) releases for the Unity Editor, while periodically providing version agnostic content, or guidance on new alpha controls when requested / needed.
