AWS UI is a collection of React components that help create intuitive, responsive, and accessible user experiences for web applications. It is developed by Amazon Web Services (AWS). This work is available under the terms of the Apache 2.0 open source license.
This release allows Amazon teams to release open source products that have a dependency on the AWS UI components. It is just the first step in a larger process of creating a new open source design system. You can find more information on GitHub.
