I think you can use Qt free license in your commercial product(distribute it or not) as long as you dynamically link Qt libraries.

- toyg 10y agoThe situation for Qt has changed several times in the last few years through the various acquisitions, so yeah, I might be a bit out of date because it doesn't really matter for PyQt itself -- that's just GPL or commercial.
- mherrmann 10y agoExactly. The LGPL (which Qt is licensed under) permits this. It also permits subclassing. What toyg wrote would be true if Qt were licensed under the GPL.
- dagw 10y agoQt is under the LGPL, but PyQt isn't. So if you want to develop Qt applications with python and PyQt you have to abide by the GPL, not just the LGPL, or buy a commercial license.
- infinite8s 10y agoYou can use the LGPL version of Qt and the commercial version of PyQT (which is much cheaper than the commercial version of Qt)
- dbcurtis 10y agopyside recently came back under the Qt umbrella, so it should be viable option again.
