Why develop with a commercial license?

The Qt Commercial License is the correct license to use for the development of proprietary and/or commercial software with Qt where you need to safeguard your development investment to secure your competitive advantage:

• Use, modify and redistribute Qt with no obligation to share your source code.
• Access technical support and product updates.
• Enjoy greater freedom to license your application as you wish.

You should develop with a Qt Commercial if you:

• Need to incorporate proprietary software for mission-critical applications that prohibits use of open source software
• Need for product warranties & indemnities
• Need to secure that your software cannot be accessed or manipulated by end users
