What is Qt

Qt is much more than just a cross-platform SDK - it's a technology strategy that lets you quickly and cost-effectively design, develop, deploy, and maintain software while delivering a seamless user experience across all devices.  

It's Fast

In software development, time really is money. That’s why Qt gives you a highly productive C++ framework complete with cross-platform libraries, APIs and tools for faster time to market.

It's Easy

Keep it simple – Qt’s easy-to-use and flexible IDE and design tools include ready-made controls and out-of-the box functionality for efficient UI design using drag and drop tools, declarative programming with QML or imperatively with C++. 

It's Future-Proof

Requirements changing again? No problem. Qt’s open, extensible and modular C++ framework supports a cost-efficient software development life cycle.

LG is not only using Qt for TVs, but for various other products and in various capacities.

What makes Qt smarter?

Rapid prototyping, development & deployment

Qt gives you mature, comprehensive, and highly intuitive APIs along with a professional IDE that offers cross-platform and cross-compiling support – meaning better productivity for any project.

Ultimate Performance, Reliability & Stability

Want instant-on, easy hardware integration, with zero overhead and full optimization? Qt’s C++ approach gives you full control over the code without compromising native performance. Let’s hear it for C++!

IDE & UI tools for both developers & designers

Qt allows you to create fluid and responsive 2D/3D UIs using declarative script programming, imperative design, or hybrid development that may even include HTML5. You pick the design approach that best suits your project and your team.

Get creative or go native. It's your choice.

Qt user interfaces present a native desktop look-and-feel, but if a custom-branded UI is what you’re after you can easily modify existing styles or create your own.

Future-proof tech independence? Totally.

Join a thriving community of 1 million+ developers, professional partners, contributors, and maintainers who already enjoy Qt's open governance and access to source code -- a transparent and platform-agnostic promise.

We've got your back with global services.

Discover our developer resources to learn how Qt helps you create connected devices, UIs, and applications.

Get exceptional support and guidance on the use of Qt APIs, functions, methods, and programing techniques.

Take advantage of our in-depth training to get a comprehensive understanding of Qt.
