> QT needs a commercial license which is pretty expensive

Are you sure about that? Most of Qt for desktop is licensed under LGPL or similarly permissive licenses that don't require you to open source your project or pay licensing fees.

Some specialized components in Qt are GPL/commercial, but those are for things like automotive use.

I use Qt/QML for desktop applications and never had to buy a license.

Check this out[1] and sort by license to see if you're actually using modules that require a commercial license. Chances are you aren't.

Half-seconded. I wouldn't claim to have fully understood how the Qt licensing model works (and I think it can be different if you do servers, or deliver binaries), but it's definitely worth checking out your exact use case, because I find developing in Qt really good.
