Write code once to target multiple platforms

Qt allows you to write advanced applications and UIs once, and deploy them across desktop and embedded operating systems without rewriting the source code saving time and development cost.

Create amazing user experiences

Whether you prefer C++ or JavaScript, Qt provides the building blocks — a broad set of customizable widgets, graphics canvas, style engine and more that you need to build modern user interfaces. Incorporate 3D graphics, multimedia audio or video, visual effects, and animations to set your application apart from the competition.

Do more with less (and faster)

With the new Qt Creator cross-platform IDE, or on its own, Qt is fast to learn and easy to use.  And Qt's modular class library means that you can spend more time on innovation, and less time on infrastructure coding getting your software to market faster.

Blend web and native code in a single application

Qt's integration with the WebKit web rendering engine means that you can quickly incorporate content and services from the Web into your native application, and can use the web environment to deliver your services and functionality impressing your users in the process.
