Case Study: KPN tests its design system 30x faster with Applitools Visual AI
Key results
The challenge
KPN, a Netherlands-based telecom and IT provider, maintained its Kermit design system and tested components across roughly 10 physical devices. Each component took about five minutes per device, making a full pass extremely time-consuming and hard to scale.
The solution
KPN moved to Applitools Visual AI with a Storybook integration, running automated visual tests across the design system's components as part of its pull-request workflow.
“So from two and a half hours per component to five minutes running for all components.”

The results, in context
With Applitools, KPN reduced testing from about two and a half hours for a single component to five minutes for all components, roughly 30x faster than manual testing. A proof of concept ran through about 600 Storybook stories in four to five minutes, letting the team gate deployments on passing visual and build checks.
