canonic VS unpoly

I just founded a company where we're building a cross-platform native desktop app. Perhaps given we're on HN we can scope this to ask why aren't any _startups_ building native desktop apps?

It's something I wonder about as well. We're building real-time performance critical software, so we don't have much of an alternative. Given these constraints, we also ruled out Electron, Avalonia, React Native early on.

We're using Qt Quick which doesn't get nearly the love it should. I was a web developer for 5 years in a past life, and I'm pretty blown away by how pleasant and well-designed Qt Quick's QML language is. One of our team members created Canonic, https://www.canonic.com to explore how the web might look if QML was used as the document markup for the web.

The popular opinion around Qt Quick is that it is best suited for mobile or embedded projects with a dynamic UI, animations, etc. But over the last few years, it has really become a great desktop solution – to the point where Qt put Widgets into maintenance mode and is focusing efforts on Qt Quick across desktop, mobile and embedded targets.

With Qt 6, the GUI is drawn using native graphics acceleration: Metal on macOS, DirectX11 on Windows, Vulkan on Linux. This makes it really easy to bring in a texture you're drawing in some other piece of code outside of Qt. As a result, the QtMultimedia framework in Qt6 is zero-copy on most platforms with the FFmpeg backend. Frames get decoded if a GPU HW decoder is available, then this texture can be read directly by QtQuick and then rendered by the display server without ever being copied. I don't think there's a single other cross platform framework out there that achieves the same level of usability, performance and easy access to platform native APIs.

Here are just a few non-trivial desktop apps that come to mind using Qt Quick:

Here's the website if you want to test it out: https://www.canonic.com

No, the end goal is to have an entirely separate browser which browses website built with all instead of html / js / css ; since Qt compiles to WASM it's a simple way to try it but the actual thing exists as a standalone desktop app: https://github.com/canonic/canonic

I really like the potential for sending minimal document elements, though it seems like these features should be built into the browser. Unpoly, for example, has its own entire reimplementation of fetch():

Do any browsers have the early workings of a native web application sdk?
