Commercial: A commercial license keeps your code proprietary where only you can control and monetize on your end product’s development, user experience and distribution – securing your intellectual property.

Qt for Application Development: Qt for Application Development is dual-licensed under commercial and open source licenses. Commercial gives you full rights to create and distribute software on your own terms without any open source obligations. It also gives you access to the official Qt Support team and a close strategic relationship with The Qt Company.

Qt for Device Creation: Ready-made solutions that speed up your device creation with enterprise-quality features for a truly professional development experience. Qt for Device Creation is a product available only under a commercial license.

Qt for Automation: A collection of modular, scalable, secure software libraries, development tools and interoperability protocols geared to make automation software development with Qt even more cost- and time-efficient.

LGPL v3: With LGPLv3 license option you can use the essential libraries and some add-on libraries of Qt. LGPLv3 allows for keeping your application source code closed as long as all the requirements of LGPLv3 are met.

GPL v3: With GPLv3 license option, you have access to almost all Qt framework functionality, as well as development and design tooling. Note that using GPL licensed framework libraries requires your application or device to be licensed under GPL as well.

GPL v2: All essential libraries and some add-on libraries of Qt are available under GPLv2 license option. Note that using GPL licensed framework libraries requires your application or device to be licensed under GPL as well.

Qt Safe Renderer: As an extension of Qt for Device Creation, Safe Renderer enables you to develop modern embedded systems that are both functionally safe and user-friendly. Pre-certified software components save time and money, and provide confidence in end-to-end certification of your safety-critical UI systems.

Qt Start-Up Plan: The Qt Company partners with many start-ups and innovators, helping them get to market faster and lowering their costs. Find out if your growing business qualifies for a commercial Qt license.

Qt Automotive Suite: A fully-fledged automotive software development toolkit built on Qt for Device Creation developed in collaboration with our technology partners, KDAB and Luxoft.

Python: Launched in 2018, the Python bindings already cover a lot of Qt. Check out the product map for the compatible components. Learn more in the Qt for Python technical documentation: https://doc.qt.io/qtforpython/
