How much cost Qt for Indie developers ?

  • Im trying to access but I cant, does anyone knows how much cost Qt License and if Digia offers Indie Licenses of Qt

    Best Regards

  • What should an Indie license be? a License is a license, right?

    The website in general works for me, and there is a "contact form:":

  • Well Indie is a meme for "Independent development" and some companies have especial low cost licenses for Indie and I cant open that page

  • You don't miss anything - there aren't any prices.

    You will have to contact Digia, either using their contact form, or

    There is even an official, "Tuukka Turunen":, present here at the QDN.

  • When the licences were still sold by Nokia, I believe that they cost something like EUR 1400 per developer for a single platform licence. You could also buy a 2 or 3 platform licence at a few hundred per additional platform. No idea if Digia is using a very different price model, but I doubt it.

    If you need more exact data, you have to ask Digia, of course.

    Note that you may also considder using the LGPL version of the toolkit. That would be a much cheaper option for an "indie", I think. The limitations are not such that it is impossible to develop commercial software that way.

  • Just a note: I think that this post maybe moved somewhere else, i.e. The lounge subforum...

    I think it is fine where it is.

  • Ooops... I was sure it was under Mobile and Embedded. Sure, it is a tipycal Independent Developer's argument :)


  • Prices I got from Digia are the same as Nokia was quoting:

    Qt Desktop Single OS – 2.995,-
    Qt Desktop Multi OS – 4.195,-
    Qt Embedded Single - 4.795,-
    Qt Embedded Multi – 5.595,-
    Qt All OS – 6.395,-

    All prices are in Euro and per developer.

    Sorry for dumb question, but i cant find complete answer for this.
    What can I get for this price?
    And what difference between opensource version and version from Digia?

  • With a commercial license you are not bound to the restrictions of the GPL or LGPL licenses. For example you can linke your closed source application statically or you can modify Qt source code without the need to publish that changes.

  • I see.
    And probably some support from Digia.

  • [quote author="qxoz" date="1322199637"]I see.
    And probably some support from Digia.[/quote]
    Yes, that is included too. However, you can also buy Qt support from other firms, no matter if you use LGPL Qt or commercial Qt.

  • That is great.

  • I find this prices outraging. They sell something you already have access to at gold prices...
    Incredible! Better to develop in open-source, which in addition gives a contribution to society.


  • If it's too expensive for your - nobody forces you to buy a license. Go with the LGPL version and be happy. There's nothing to flame about this. If you run a business making money out of the software you build on top of Qt, it's likely that the license fees are negligible compared to the other costs. And there's more you get for the money than only the license, e.g. dedicated support, bug fixes, etc.

    Let's be happy that there are that much options and everyone can choose what fits ones needs.

    You are right. :-)


  • I'm happy about that, but I just don't know why it's so hard to figure out the prices. I got a credit card ready, but haven't heard back for about a week on the prices.

    I feel bad for the credit card, they're really big prices. In their site they tell you the benefits of a commercial license.
    (I'd love to be able to statically build without having to purchase... But well)

  • [quote author="Blastcore" date="1357367540"](I'd love to be able to statically build without having to purchase... But well)[/quote]You are, just release your application under the terms of the GPL or LGPL.

  • I’d love to be able to statically build without having to purchase…

    Unfortunatelly in static linked Qt 5.0 not worked QML 2.0 feature, also you can't link static with ICU and Angle (used in Qt 5.0).
    This way commercial license have no benefits except paid support.

  • Qt would not stand where it stays today, if they would not have so many developers. And most contributions are not made from hobbyists, they are made by commercial programmers. If I
    sell successfully a commercial application, I would be happy to buy a licence, because I make sure that my foundation will not break away. And that is quite a crucial benefit.... Just my two cents.



  • It is a pity Digia doesn't distinguish between rich corporations and poor independent developers. And I keep hearing stuff like "It is not expensive" mostly by people whose sight goes about as far as their noses, in complete ignorance of the fact many people in the world still have to survive and provide for families with monthly pay that is lower than a day's pay for others. That is right, the average monthly pay where I come from is less than a day's pay of an average C++ developer in western nations. But hey, since when do rich people give a damn about the poor?

    Paid support I can live without. I never ever resorted to customer support with the exception of returning faulty hardware. It is a very ugly thing that Digia don't take into consideration the financial capabilities of developers, especially after they got Qt literally for peanuts. Maybe I'd understand if they (over)paid as much as Nokia, but getting it so cheap and milking it so hard draws a picture in a pretty greedy tone.

    And while some people say "what do you care, just use LGPL and link dynamically" but many others seem to think that if you develop closed source applications you pretty much have to go commercial, the whole subject is very vague, everyone gives a vague answer, so the poor independent developer is faced with a dilemma - just as he can't afford to buy a commercial license he can't also afford to get sued.

    So how does one start developing and selling his software so he can reach the point of being able to afford either the ridiculously high priced commercial license or the ridiculously high priced legal council?

    And excuse me but those prices are not just high relative to the standards of people who live east of Germany, they are also quite high compared to other similar products:

    C++ Bulder XE3 Starter - 236 euro
    C++ Bulder XE3 Ultimate - 2676 euro
    C++ Bulder XE3 Pro - 891 euro
    C++ Bulder XE3 Enterprise - 1784 euro
    Juce (single product) - 399 pounds
    Juce (unlimited) - 699 pounds
    Visual Studio 2012 Pro - 600 euro
    Marmalade SDK Indie - 499$
    Marmalade SDK Plus - 1499$
    MoSync Basic Pro - 199 euro
    MoSync Gold Pro - 2999 euro
    MoSync (without support) - FREE

    And all those include multiple platform support, which for Qt comes at in excess of 6000 euro. And this only for the currently supported platforms, there is still the possibility to jack the price even further once iOS and Android are supported.

    With all the ambiguity the only good LGPL serves is to attract more potential commercial customers, not to mention it can very well entrap naive people into legal troubles. Surely it must be safe to develop open source applications, but the question is who will pay for an open source application? Maybe a few people will pay for support, but that implies you already have a business with support staff, which is hardly the case of start-up indie developers.

    A much better option for indie developers would be to get commercial license at the cost of 10% of your application sales. Whether you are entitled to support and how much would depend on the scale of your operation. When or if you get big enough - switch to the current fixed price licensing scheme. This approach would make it much easier for indie developers, but it will also increase Digia's profits, provided of course it is willing to collect amounts below 4 digit, and most importantly - it will provide the possibility to start up and grow big enough to be able to afford the full blown license.

    Otherwise, it is just discriminatory towards people whose only fault is no one asked them about the geographic coordinates to be born at.

  • utcenter: Have you bothered to ask about prices yourself or is this rant based entirely on hearsay?

    At least please do not put the blame for the complexity of laws surrounding licenses at our door. Every country thinks it is a good idea to come up with slightly different rules, there is nothing we can do about that. What we can do is pick a widely used (and hopefully understood) license like GPL or LGPL. Guess what: Those are the licenses Qt is under for a long time now.

    We do have lots of idealists here at Digia that work on Qt because they want to have a good free (as in freedom) library available for everybody. I am one of them and find your claim that the LGPL license is only there to "entrap naive people into legal troubles" or to "attract commercial customers" insulting. A lot of work was put into those licenses by the FSF to make them as clear as possible. A lot of developers have written code under those licenses, because they do like the ideas encoded in them. I feel that your claim belittles the hard work of all those people in addition to anybody contributing to Qt -- inside and outside of Digia -- because it is free software.

    Before you ask: I am not only idealistic but also hungry. I am more than fine with the commercial license option;)

  • I've got enough sources with sufficient consistency across the board to justify assuming their legitimacy. Or maybe you imply I am going to get a different answer? Anyway, I am not in the habit of asking the price of things I can't afford - it is pointless. And furthermore - every similar company has been "kind" enough to provide public pricing, that's how consumerism works - you have a product, you put it on the shelf and you put a price tag on it. What's the deal with having to ask? To be honest I am more curious about the reason why than the actual price.

    Whether you feel insulted depends more on you than on my intent. I've seen my fair share of people who look down on the less fortunate, like if they cannot afford to fund intellectual activities they should quit and instead get into something more fitting their stature - like digging in the garbage cans for food scraps and stuff like that. But unlike you I won't get insulted just because you hold the underprivileged in contempt.

    A multi platform commercial Qt license is a month's pay... if you've been lucky enough to be born in the right place. Sadly this applies to a very small portion of the world population, as a sentient adult you should be aware of that little fact. Glad to hear you are in good financial health, and I wish you live long enough to experience the effects of the poverty that's creeping from east to west. Perhaps then you will understand what you fail to understand today. It wasn't always like that here you know, but one morning you wake up and you find your savings have lost three zeroes, cost of living higher than in rich countries, unemployment skyrocketing and pay - conflicting you whether you should laugh or cry.

    If the intent of the company you represent is as noble as you appear to imply, it should really do something more to help people start up. I am not talking about charity, I am talking about a chance to start up and be able to afford your product through your product.

    Also, correct me if I am wrong, but Qt under LGPL is not a product of Digia - it was done by Nokia. At this point it is unclear if there would be a LGPL option if it was up to Digia. And LGPL is still here because Digia can't remove that option, even if they wanted to, right? So if I were you I wouldn't talk about noble aspirations before there are any expressed in action.

    Last but not least - like 99.99% of the people I've interacted with, you seem to be unclear on the concept of Idealism and Realism as defined by their pioneers - Aristotle and Socrates, and instead harbor the "popular" concept which is pretty much the full opposite of what was originally intended. If you were Idealistic in the true meaning of it - you'd not conform to the static way things are and accepting it for granted and would instead be willing to explore a more flexible solution that better fits the varying scenarios.

  • I said that it is insulting to call LGPL/GPL traps for naive people meant to lure them into legal trouble. There was lots of thought, time and energy put into those licenses to make them as clear as possible and to minimize legal risks for everybody. All that is completely independent of Qt.

    A company is a legal construct with the aim of earning money, nothing more, nothing less. I did not imply that any company is more or less noble than any other company. I do not see where you got that impression.

    Since I do not know much about Qt pricing I can not comment on that topic.

    It is sad that you have fallen on hard times. But how would a commercial license for Qt help you in your situation? You are free to legally use Qt already.

  • Don't worry about me, I am describing the situation around me, I am fortunate enough to be a little better than my surroundings, even if still pretty bad compared to your standards. It is not an individual misfortune, this is the reality of most of the people round this part of the globe.

    bq. You are free to legally use Qt already.

    But am I? What's to guarantee that, besides wishful thinking? Also use as in? Tinker with? Learn? Make money on? After spending a lot of time investigating the matter I honestly don't feel 100% safe doing the latter.

    I admit, I am yet to launch a mass application, I am pretty new to Qt and so far have only done a few highly custom applications for individual clients. Mostly under the table, so no worries there. I would like to launch mass applications but I don't have the resources to afford neither the commercial license to feel safe, nor the legal representation to feel safe with LGPL.

    I am also yet to stumble upon a success story of a sole independent developer who makes a living on Qt under LGPL. The few people I know working with Qt professionally are employed by fairly big companies abroad, Qt is rather unpopular on the local job market, which is odd considering I live in a 2+ million people city.

    I'd be willing to part with 10% of what my products would generate, whether that is 1000 or 1000000, but taking a few thousand euro out of my pocked in advance - I honestly don't feel comfortable with, considering the grim and worsening financial situation. It is not that much a matter of not having the money, it is a matter of not being able to afford it, there is a subtle difference.

  • We're a company that sells our devices with the related software world wide. And we have no issue at all using LGPL Qt. There are many other examples. Qt even has a special exception that explicitly allows you to use things like templates, structures and constants defined in the Qt headers without that leading to you having to open up your sources.

    Before my current job, I also have done work as an independent contractor for several clients. There too, I have used Qt under LGPL successfully. So there you have it: your success story.

    It is nobodies fault that you "don't feel comfortable" with using LGPL. I think it is the most liberal license you can reasonably expect for something like Qt. Seeing that Digia employs over 80 developers (not counting support) to work on Qt, I think the prices are reasonable. We'd all like to see them lower, but it is the way it is.

    You make it sound as it if is based my choice, but in reality it is based on the information available, to a large extend the information made available by Digia. And yes, I keep in mind the fact that Digia representatives may be inclined to bias toward the need of commercial license.

    Thanks for sharing that information.

  • Come on, the license text is right there to read. Futhermore, LGPL is is all over the net. What more information do you need exactly?

  • I would be able to follow your argument if Qt was under some obscure license (anyone remembers QPL?), but GPL/LGPL are two of the most widely used and discussed open source licenses available on the planet!

    When you are going to build a business, you will need to understand the legal implications of your actions. Software licenses are one part of those legal implications you need to understand, it does matter little whether those licenses are open source ones or proprietary.

  • IIRC there is still some ambiguity in LGPL concerning the interpretation of some legal definitions, and then there are the other licenses of other Qt components and IIRC must also be taken in consideration.

    The legal and IP systems are a mess of nonsense and I really don't think I can force myself to "understand" such, that is why I think it is preferable if there was a more affordable commercial licensing option, so I can think about application development instead of legal nonsense. If Digia is that much concerned with the collective well-being, it should include licensing options suited for small and independent developers, so we can develop in peace. After all, a modest fee is better than no fee, isn't it? Or perhaps it is below the dignity of your company to bother collecting bellow a certain amount?

    You know that some time ago an Australian person actually patented the wheel, hidden behind a more obscure technical definition, just for the sake of proving how ridiculous the whole subject is.

    Self-employment has already forced me to become part-time-accountant, and that is one nonsense too many on my head already. So pardon my lack of enthusiasm when it comes to legal issues as well.

  • Patent law is something separate from software licenses. While that too is an interesting discussion, let's not confuse the issue at hand even more.

    I don't think that it has anything to do with being "below the dignity" of Digia (and before them, Nokia and Trolltech). I guess (not know) that it is a matter of company economics: there are costs involved with dealing with contracts and customers, and even more so with contracts for sales-based licensing fees. I think Digia simply figures that the costs involved don't weigh up to the income and the risks involved. After all: if you say that you want to pay a fee per shipped product, that also means that there would need to be communication about that, time and time again. It needs administrating. It needs checking. It can only be done after the fact, and that means Digia would have to go after companies and "Indies" to collect the actual fees. If that is possible at all (businesses come and go, people may be hard to locate, etc).

    I have also seen the commercial license terms. They are not a pretty read either to be honest. I think that with any contract, especially for companies operating globally, there will be difficulties interpreting the exact terms that apply, and how definitions in there match the ones within the legal jurisdiction you're in.

    Do you have any evidence of problems caused by applying an LGPL license? Have you ever heard of Digia or Nokia going after developers using it?

  • So somehow Digia's costs are a lot higher than those of other companies who do offer more affordable licensing? If other companies find it economically viable to collect 300-600 Euro, why should it not be possible for Digia?

    And no, in my last post I wasn't talking about a percent of app sales, but a more affordable indie license cost, something more reasonable like 600 Euro. I'd be happy to get a commercial Qt license for 600 Euro, which is in check with what other frameworks cost indie developers. As the size of my operation grows there won't be a problem switching to the 6000 Euro version.

    No, I haven't stumbled upon stories of Digia going after anyone, don't know if there are such cases, but if there aren't that might be because others exercise the same caution as I do. Better safe than sorry right?

  • Well, you just said:
    [quote]I’d be willing to part with 10% of what my products would generate, whether that is 1000 or 1000000, but taking a few thousand euro out of my pocked in advance – I honestly don’t feel comfortable with, considering the grim and worsening financial situation.

    I took that as a request for taking a licensing fee based on sales.

    Now, it seems that all you really want is a 90% discount. Based on what criteria exactly? Why would anyone buy a full license if they can get the same for only 10% of the price?

    It really seems to me, that you have plenty of options already available to you. You can use LGPL, you can use GPL (yes, you can make money with GPL-ed software) or you use a commercial Qt license. Or, you take a cheaper, competing framework.

    Anyway, I am not in sales, and hope I will never be. I don't design pricing plans for any company.

  • bq. and no, in my last post I wasn’t talking about a percent of app sales

    I'll be happy with either of the options. I proposed the 10% scheme because it will be better for indie developers as well as for Digia. But an affordable indie license is just a good.

    No, I don't want discount, I want a license option that is reasonably priced according to individual independent start-up developers. I am even willing to leave out modules I don't need, if you really feel like а reasonably priced indie license will rob the revenue. Plus as I mentioned previously - I could also go without actual customer support. But still, 600 euro is better than 0 euro and it paves the way to 6000 euro.

  • OK I can't say I'm a huge fan of the current licensing arrangement.

    Having tried to get my head round it for a while I have come to the following
    License is actually a pretty good deal for many independent developers. More precisely,
    the developers that don't need to modify QT source and don't need to statically link don't
    seem to need to pay a thing (which is why I say its a good deal).

    Unfortunately if you do need to do these things then its very painful indeed.

    Now why all the confusion about the license ? I think its probable that Digia want to sell as many
    Licenses as possible so don't mind having a little uncertainty in the minds of the richer independent
    developers (ones can afford the price but might skip the payment if they thought they didn't need
    to pay) What I'm saying is there are a certain number of cashed up developers that roll their eyes
    at all the legal mumbo jumbo and reach for their credit card.

  • What confusion?

    You require a commercial license for static linking and closed-source modifications of Qt; if you get along with dynamic linking and the fact, that you will have to provide the sources of modifications of Qt (not your application) if you publicly publish your application you will get Qt for free under the terms of the LGPL or the GPL.

    If you are interest in the prices of Qt feel free to ask Digia.

  • Thanks Lukas you just made something more clear to me: So I can use QT for free
    for a commercial closed source application provided I 1) use dynamic linking 2)Publish source code of modifications to QT. Cool, since I'm happy to publish my mods to QT (if I make any)
    and for most application style applications dynamic linking is preferred as a matter of good software engineering. So as far as I can see the only real prohibition the on use of the free
    license is using QT to make binary libs, since these must to be statically linked.

    I still do like my confusion theory its got a nice whiff of conspiracy about it.
