Change the UI style of ReadyAPi 4.0?

Hi, thanks for your honest feedback. We updated the ReadyAPI UI in response to customer requests for a more modern experience and to align with the updated SmartBear design system, which also gives us a stronger foundation for improving accessibility going forward.

We recognize that the 4.0 release introduces significant UI changes that may require an adjustment period for existing users, and that some areas may currently present usability issues or inconsistencies, including the ones reported here. We’ve documented the known issues and are actively addressing them.

A patch release is planned for next week to resolve the reported endpoint editing issue and additional UI concerns raised by customers.

In the meantime, ReadyAPI 3.67.0 remains fully compatible, so teams can continue working without disruption while we roll out fixes and improvements. Download installers from the ReadyAPI Downloads Center.

We appreciate the feedback and encourage you to continue sharing your experience — it’s helping us prioritize the updates that matter most.
