Rapid Meets Responsive Design

Delivering a great user experience is a crucial component to any digital initiative. But even expert JavaScript, HTML5 and CSS developers say it’s time consuming to create great, consistent experiences across form factors and mobile platforms.

The Atlas UI Framework addresses this challenge, while remaining standards-based, open and extensible. We put responsive UI design in the hands of rapid developers through a fully open source, responsive framework integrated into the Mendix visual development environment. With Mendix, even non-designers can quickly create rich, great looking apps that automatically adapt to all device form factors.

Page Templates

We provide out-of-the-box templates for a wide range of page types, including Overview, Master-detail, Dashboard, Location and Wizard.

These templates are available for every type of device. Our UI framework also comes with a fully responsive Layout Grid so you can define specific layout behavior for smartphone, tablet and desktop.

User Experience Design Tools

Building Blocks

Speed development of custom pages using building blocks: assemblies of multiple, pre-configured widgets that can you can drag and drop into pages to implement common UI patterns, such as headers, timelines, and wizards.


Further build out your pages by adding additional widgets from the rich set of user interface elements that come with the platform, as well as an ever-expanding set of widgets found in the Mendix App Store. Widgets are styled automatically by the theme, but can be customized on a case-by-case basis if styling or placement isn’t quite right.
