It's licensed under LGPL 2.1 (or GPL3 if you prefer), so it's free for proprietary/closed-source usage as long as you don't modify Qt itself, or if you at least distribute the source code of the modified Qt binaries. There is also a commercial license if you want support or to be able to modify Qt for a closed-source project, but that requires direct contact with their sales folks afaik.
- wildranter 14y agoThanks for your reply. I was considering using wxPython for my next project. But this licensing leans me towards Pyside+Qt.
- easytiger 14y agoi would assume the more interesting information is how much does it cost to license in a commercial project.
