[Interest] Qt Creator licensing for companies with Qt Commercial developers

Hi,

The question was related to mixing open-source and commercial version of Qt in the same project. See Qt licensing FAQ: https://www.qt.io/faq/

It states in question 2.7.: ”Q: Can some developers in our team working on the same project use open-source version of Qt and some developers use Commercial version of Qt?
A. No. Each developer must have their own assigned Qt license. Mixing Qt commercial licenses with Qt open-source licenses in one project/product is not permitted.”

Qt Creator under GPL license can be used for developing closed software. The restriction about mixing commercial and open-source Qt affects the case originally asked.

Yours,

                Tuukka

Maybe I misunderstood something so just correct me.
If I use – commercially – QtCreator as my daily IDE without using Qt library or attached modules, I still need to pay for full Qt license?

Cheers,

Hi,

is it just me or this is heading into the wrong way, or at least into the opposite direction of the market. Most IDE are now free, even the embedded world start giving IDE away:
xCode is free
vs code is free
Atollic is free
STM32 TrueStudio is free
..

People are leaving pricy IDE behind, Keil anyone? less and less used. Starting to pay for an IDE like QtCreator, seem like you will only get less users toward Qt or people might be temped more and more to use VisualStudio as an IDE of choice.

This is my personnal point of view on the subject,
My 2 cents,

Hi,

Correct. All users need to have commercial license. It is not allowed for part of the team to use commercial and part use open-source. Even though Qt Creator is great, it can feel odd to pay for full Qt license and only use the Creator IDE.

We have been thinking about selling Qt Creator separately, but so far no decisions made on this.

    Hi,

    Situation.

    A company has a few developers with Qt Commercial subscription who
    write applications in Qt for iOS.
    There are many other developers, who work on other projects and don't
    use Qt libraries.
    They talk to each other and sometimes even work on the same code.

    Is it still possible for the developers who don't use Qt libraries in
    any way, use Qt Creator IDE for editing and debugging?
    To be on the safe side, company plans to prohibit usage of Qt Creator
    IDE for all employees.
    I reckon this is a popular solution.
    If I understand correctly, Qt even sells a special option to ban all
    company IP addresses for open-source installer.

    But is it really so?

    Vyacheslav
