What Designers Are Saying
Gabor Boszormenyi
This UX Kit is a game-changer for my design process! With its extensive set of components, I was able to produce high-quality wireframes for my clients in no time. The automatic breakpoints save so much effort, ensuring designs are responsive from the start, and the fully tokenised components make customisation seamless and efficient. It’s an excellent tool that truly elevates the quality and speed of my work!
Ian Weir
What sets Flex apart isn’t just the quality of the components- it’s the care and craft behind them. Every aspect feels reassuringly considered and detailed. It covers many sectors and use cases, yet it’s clearly explained with extensive documentation. It’s become the go-to resource for any project.
Rafael Kent
The Flex design system kit is a comprehensive and well-documented resource for quickly creating wireframes and user journeys. Freelancers and in-house designers alike will find it invaluable for meeting client expectations and deadlines. Its robust features and polished aesthetic make it a truly valuable tool.

Still got doubts?
Can a beginner use Flex Design System?
Absolutely. Flex Design System was created for both professionals and those learning Figma and UX Design. The online documentation provides a comprehensive explanation of everything you need to get started quickly.
Can Flex DS be used for UI design?
Flex Design System was primarily created to provide UX designers with a comprehensive suite of consistently styled components for producing world-class UX documentation. However, its fully customisable and extensive design also makes it easy for UI designers to use.
Is there a free trial?
Currently, there is no free trial, partly due to the nature of digital downloads and the significant investment of hundreds of hours in creating Flex Design System.
However, you can explore the preview to get a better idea if it is right for you, prior to making a purchase.
Additionally, great care has been taken to provide extensive documentation to help you get up to speed as quickly as possible.
