Pricing, Packaging and Licensing for Qt

In order to distribute a Qt-based application on devices (joint software and hardware development involved) under the Qt commercial license, distribution licenses are also required. Please contact us to determine if you do require a distribution license.

If you have chosen the commercial licensing, each Qt developer must have their own assigned Qt commercial license. It’s not permitted to mix Qt commercial licensees with Qt (L)GPL licensees in one project.

The Qt Framework is dual-licensed under commercial and open-source licenses. The commercial Qt license gives you the full rights to create and distribute software on your own terms without any open source license obligations. The Qt open source licensing is ideal for use cases such as open-source projects with open source distribution, student/academic purposes, hobby projects, internal research projects without external distribution, or other projects where all (L)GPL obligations can be met.

If you are a legacy perpetual license holder, you can continue to use your Qt license if you choose not to renew your annual support & maintenance contract. Please note that you will not have access to support, bug releases, or patches. If you are a term or subscription license holder, your rights to continue using the tools, APIs and libraries expire when the term expires, or the subscription is canceled. You will not have the rights to future development or distribution.  

No. You are not permitted to further distribute your applications.

If you have unused Qt for Device Creation Distribution Licenses, you may continue distribute the application with your device for a period of 6 months. You are however not allowed to further develop or maintain the applications.

You can cancel your subscription (Qt commercial license or specific Qt modules) at any time and won't be automatically renewed at the end of your current term. However, note that when your subscription has ended, you will not be able to access Qt Creator or specific modules and continue developing. Our tools and modules are only available with an active subscription.

Your commercial or open-source license is not bound to a project, especially your active commercial Qt license is eligible for several development projects. However, you are not allowed to mix open-source and commercial projects/developers. Either your project follows the open-source obligations or goes under Qt commercial where all related Qt developers have the right commercial Qt license.

Yes, you can use your commercial or open-source developer license for multiple projects. But you are not allowed to mix projects done under open-source obligation with Qt commercial ones.

Yes. If you are defined as a License Manager for your team, you can assign licenses from one user to another in your Qt Account under the Assign licenses section. Note that the License Manager can assign licenses only once within six months.

Every commercial license has its own license manager. This person can be the same person as license holder or another person in your team. Changes or requests for defining the License Manager in your team can be ordered from the Support Center by opening a new support request. The License Manager can assign licenses from the user to another in his Qt Account.

Either your License Manager can reassign your commercial license, or you can inform our Support team about the change by opening a new support request in Support Center (QtAccount).

Mostly all commercial licenses come with Standard Email Support with a 24-hour response time available through your QtAccount. Only the EDU and Small Business licenses either have limited or no support.
