I love one of the responses:

> Sure QT can create cross platform UIs, but with a $300 yearly price tag for one developer and no support.

It's kind of amazing that we've gotten to a world where $300 for high-quality dev tools is considered an unreasonable price. If your software has any kind of revenue model at all, $300 a year is nothing! Cripes, I'm old enough to remember the days when you had to pay companies like Microsoft four figures per year per developer just for access to documentation.

Except you can use Qt for free in proprietary applications too, the response to that comment makes it clear.

You can, but then you have 50MB of useless DLLs that static linking would eliminate. At that point you have the same disk footprint as an electron app. Memory use would still be order of a magnitude better though.

This is not true, did you mean 50Mb ? And do you staticly build GTK or Electron?

Qt is split into modules, so if you don't use Webkit you don't include that module, if you don't use networking you don't include that, if you only do a CLI app you don't include the GUI module.

Its been about two years, but ~50MB was the range. Its quite possible the necessary optimization wasn't done (I wasn't responsible for that). But internal builds with static linking gave you that for free.

Maybe they were using some debug version and maybe bundled 32 and 64 bits in the same package(I think for OSX had multiarch packaging a few years back when I was making Qt packages)

I just checked VLC now and the Windows download has 38Mb, Qupzilla installer has 78Mb(this is a browser so it bundles webkit and probably some js enbine),

This was on Windows, and dynamic linking as the project was proprietary. If you pay the fee or are open source you can static link and it will be much smaller.

I still don't believe that the Qt dlls are 500Mb, I tried to Google around and what I found is someone complaining of the size, in his case a simple Qt GUI app had 14Mb. If you think 500Mb is the right number maybe you can find a link so I update my knowledge.

I am familiar with this complaint , at a previous workpolace we switched to Adobe AIR because of the installer size (the boss felt better if the customers installed AIR from Adobe and then our 2 Mb installer). At that time Qt did not had a built in way to create installers, signing them, and autoupdate applications,(not sure it has now) Adobe AIR had such mechanism so this also was a factor on switching to this toolkit then.

So if you think Qt is big what would you use instead?

Fifty. Not 500.

You misread my original comment, and the follow up.

I thought you were being smart with 50 megabits in your earlier comment or I would have caught that misunderstanding earlier.

Sorry, I can swear it was 500 but my eyes tricked me.

You did not mention what cross platform tool is smaller and works with proprietary software.1
