Is QT Free to use or NOT?! Is QT Free for commercial use? QT For Python, C++, Android, iOS

"If you use Qt open-source and you comply with LGPL licence, you can sell your app without releasing your source code. Make sure you only use LGPL modules only and link to the library dynamically. There are several companies doing so in their comercial software."

Nice show man. Just curious, what font did you use for your thumbnail of the video?

Can i use external python libraries in pyside6 and still able to sell the app without buying the premium licence?

The video is very good, but I had a doubt. If I develop a program to use internally in the company, can I use Qt Open Source?

It's cute not QT!

I want to make advanced dashboard for my trading bots with this application, it’s personal and i will not sell it to any one and on any store , does it free to use ? And what is the difference between this and Qt design studio ?

I have an assignment from the company where I work to create a GUI software using pyqt5 for the purpose of simplifying data input. if i just use python pyqt5 library without changing the pyqt5 library. is it still free?

"you have to release modifications made to qt program" - this statement confuses the hell out of me. If I am simply using qt standard library and putting them together to build my application, I am NOT modifying qt's source code am I ?

即使使用了静态链接 ，也能使用LGPL许可证，只要提供一个可以编译，但隐藏了你核心代码的工程，让想替换LGPL库（Qt）的人可以用工程编译成功就行.

Thanks for your video, but It was more confusing than I could imagine ))))

Thank you for this useful video! Have a question though: if i build an android app using qt and i release it on the store, not for earning any money (no purchase fee, no advertising and no buys included) but also no open source code, is it legit?

What if I develop a data analysis tool with Qt which helps me to develop my actual application which is not based on Qt? I don't sell my analysis tool but I use it to develop a non Qt application. What do I need to consider regarding licenses?

thats why use presentation programs. you can summarize all content in one table.

Very useful summary, thanks :-)

Hi, if you use pyside for code an App and you don’t want release the code, only sell the App ( not in a Sw Store), you must buy a commercial license of qt? Or is not necessary? Is this the same for Pyqt? Thanks for yor fantastic work

I have been dwelling with Qt License for a while.

I want to build simple widgets for work. Apps which are just built for improving productivity.

For Example building a Calculator and then release it. I don't intend to (or Know how to) modify the Qt source and I will link the Qt Libraries linked externally. There will be no money earned from the app, however the source cannot be released commercially. Do you think I will need a commercial license in this scenario?

Can we use QT application commercially or sell them , if we don’t modify the QT framework source code??

Sounds a bit confusing.

Thanks for the video. It confirmed what I was thinking but I'm not really familiar with licensing so it is nice to have that confirmation.

Do we need to purchase a license of qt for python if we are writing a book

Hola, la licencia también se relaciona con el uso de Pyside6 y QT6?

what if i want to build apps for my own use and not distribute them public? can i go with this open source licenses and which one?

Inspite of these incredible and useful videos on this channel, why it is so underrated? I am gonna help him by sharing these videos to my friends.
