Qt / QML

The standard framework across desktop, embedded and mobile platforms

Today, Qt is the most established and mature UI framework for building cross-platform desktop and embedded applications. It is used in all industries to create dashboard UIs, industrial HMIs, complex scientific or commercial desktop applications, rich-connected embedded devices, and more.

Over the past two decades, KDAB has cultivated unique expertise in software development with Qt and QML. For a long time, KDAB has been the largest external contributor to Qt and has created a wealth of useful, primarily open-source, tools and libraries to make developers' lives easier and improve code quality and performance. It is no exaggeration to say that our experts know Qt inside out.

“KDAB as a partner, supplier, and innovator helped us very much to develop and maintain our Qt code interface.”
