Get started with dedicated authoring tools

UI Toolkit’s dedicated authoring tools include the UI Builder and UI Debugger, inspired by web technologies to offer a familiar experience. Use the UI Builder to visually create and edit UI for games and applications directly in Unity, while the UI Debugger helps you resolve issues quickly.

Render dynamic text

The font rendering technology of TextMesh Pro has been integrated into UI Toolkit to help you get started without additional plug-ins or packages. You can now use advanced styling capabilities to cleanly render beautiful text at any point size and resolution.

Animate UI with lightweight transitions

UI Toolkit comes with a dedicated UI animation system that simplifies producing UI transitions in your projects. This new system even allows the efficient authoring of reusable transitions, the majority of animation in most UI projects, to save you valuable design time.

Harness crisp, textureless UI rendering capabilities

Set border radius, color, size, and text to create textureless UI elements directly in the UI Toolkit. Stop creating and importing images from Photoshop to significantly reduce the time wasted transitioning between tools, while also lowering the overall memory footprint and build size to scale more efficiently.

Unity Editor with customizable features

Develop custom UI and extensions for the Unity Editor

UI Toolkit includes a retained mode UI framework that simplifies the development of custom UI for Unity Editor extensions, so you can build unique windows and inspectors to power streamlined workflows for artists, designers, and programmers.

Other features

Iterate faster

Work and iterate more quickly with global style management and live authoring capabilities.

Familiar experience

UI authoring tools and workflows are inspired by standard web technologies for faster onboarding.

Better collaboration

Logic in C# code, UI structure in UXML documents, and styling in style sheets make it easier to work on different parts of the UI without collisions.

Rendering performance

Get greater control over the performance of your game using Render Hints and dynamic texture atlas.

Plays nice with others

UI Toolkit can be used alongside IMGUI for the Editor and UGUI for runtime. It’s also compatible with Unity’s new Input System.


Share styles and widgets within or across projects, as well as between the Editor and runtime.

Compare Unity UI systems

Although Unity recommends using UI Toolkit for new UI development projects, there are still cases where it makes sense to use older systems due to features found in Unity UI (uGUI) and IMGUI. Compare UI systems in Unity to evaluate what works best for you.

Frequently asked questions

When should I use UI Toolkit vs Unity UI?

UI Toolkit is recommended as an alternative to Unity UI for creating screen overlay UI that runs on a wide variety of screen resolutions. It should be considered by those who produce work with a significant amount of user interfaces, require familiar workflows for artists and designers, and/or seek textureless UI rendering capabilities.

Unity UI is the recommended default solution for users who need UI positioned and lit in a 3D world, as well as VFX with custom shaders and materials, and easy referencing from MonoBehaviours.

Can I use the UI Toolkit with Unity UI?

UI Toolkit is compatible with Unity UI, so you can transition existing projects without having to rewrite the entire user interface. This means that you can recreate parts of an existing project with UI Toolkit while leaving the rest in Unity UI, to have them working in conjunction on the same project.

Can I use UI Toolkit to produce world space UI?

UI Toolkit does not currently support UI elements that are positioned or lit in a 3D world. It is possible though to have screen space UI elements following world space objects.

Can I use UI Toolkit with DOTS?

You can interface with UI Toolkit from DOTS Systems on the main thread, like other built-in engine features.

Does UI Toolkit provide data binding?

UI Toolkit does not currently provide a data binding solution, UI element values must be set via C# code. Data binding is planned for the next major UI Toolkit release.

Is UI Toolkit compatible with the Unity Vector Graphics experimental package?

Yes. Even though experimental packages are not officially supported by Unity and therefore not recommended to be used in production, UI Toolkit will support SVG assets if the Vector Graphics package is installed.

How do I get started?

UI Toolkit is available as part of the 2021.2 release. Get access to UI Toolkit from the Unity Hub or on our download page.

What is the future of UI Toolkit?

Our goal for UI Toolkit is to provide a single solution for producing user interfaces that will meet all the needs of developers and designers working on Editor tools or runtime interactive experiences.
