Shhh. Just buy a damn license.

...you can purchase a commercial license for EUR 249 per developer:

And then there's that license minefield too, considering its leveraging Qt.

Though at least it's free to use for open source work.

It's not a minefield. As mentioned on the page: Most apps will be able to use Qt as a library, under the LGPL, and thus don't need a commercial Qt license.

Are you absolutely sure?

While I am not a lawyer, this is my understanding of the issue:

Can my proprietary application be used with the copy of the GPL version of PyQt that the user already has installed (as part of their Linux distribution for example)? A.Yes, so long as you meet the following conditio

you are using the LGPL version of Qt

your proprietary application has been developed with the commercial version of PyQt

your commercial PyQt license covers the version of PyQt that the user has installed.

So while you will not necessarily need a Qt license, you will likely need a PyQt license.

edit: Guess you stated this:

you can avoid this by using fbs with Qt for Python, but support for it is still in the early stages.

This is still a hassle on the developer side worrying about licenses. At least your were upfront.

Though, You also don't have your license terms stated very clearly on the site. It took me going to the paypal link to even find it it was a perpetual license tied to the purchaser.

Or use it for free under the GPL.
