fbs author here; The Pro version of fbs [1] now supports Python > 3.6 and recent Qt versions.
Question - do you have any comparisons on the size of the resulting distributed executable compared to Nuitka, pyinstaller?
This is the issue I've faced. Nontrivial programs (that, say, import pandas, numpy, selenium) are huge, implying a ~250MB+ download for the user - and then maybe up to 1GB in disk when its all unpacked.
Buying the Pro version still leaves one to deal with Qt licensing does it not?
I was suggesting that, for you to make more $$$ from it, its better to provide a free trial period for the said version.
It's documented very well, extremely easy to use and the pro version is priced very well.
