Mobile Architect @Jitsu

I hate to sound cliche, but Widgetbook Cloud has been a game changer for us. Widgetbook Cloud has helped us accelerate Flutter UI development by allowing it to happen earlier in the development process and allowing non-developers an easier way to collaborate and reason about the mobile experiences we build into our apps. Widgetbook Cloud helps us focus on the right things at the right time and it has made a huge impact on our business

Game Dev @CherryBit

Widgetbook not only helps me during development time of my Open Source design system library, but also provides an organized and easy to use catalog for the community interested in the library! It is a must have for any design system project made with Flutter

Arthur Schenk

Team Lead @Salto Cloudworks

Widgetbook Cloud saves us a lot of time and provides valuable insight into which changes are made with each merge request. This prevents problems in the UI, and our workflow became certainly twice as fast.

Case study

Mark O'Sullivan

Founder @Caza de Casa

Adopting Widgetbook has been a game changer for how we build at Caza de Casa. In one click we can quickly change state, screen sizes or even locale to view translations within our app. Less time spent setting up custom screens inside of apps to adjust state. Less time adjusting routing and adding custom mock data to view the page we are currently working on. Less time waiting for 5 different emulators to check if the screens look good on all of them. Instead more time focusing on what matters most, building and delivering the best product for our users.
