Preview the new Pega Platform™ user interface in a development-ready testing environment.

Pega is currently in the process of redeveloping its run-time environment for the React UI, which supports the latest open-source technologies and frameworks. Because the React UI performs exceptionally well with rapidly changing data sets, its use improves performance, interactivity, and response times, which creates a more fluid user experience.

In the 8.4 release, you can opt in to the React UI in App Studio to explore the new development environment and experiment with building sample applications. If you use Pega Cloud Services or a client-managed cloud environment to host your Pega Platform, the React UI engine is already a part of your development environment, and you only need to enable it for your applications. If you run an on-premises environment, you can opt in by downloading the React UI Docker container from the Pega public repository and installing it manually.
