> Avalonia's big money-maker is their drop-in replacement platform for WPF, which allows you to basically take an old WPF application and turn it into a Windows/macOS/Linux/web application with two lines of code, if you're willing to pay the price. Perhaps they'll add some kind of auto-mobile-form-factor conversion to that system as well? Ah interesting, I didn't know this. > A mouse+keyboard design just doesn't fit a mobile screen well, you're going to need to redesign and reimplement large parts of your application regardless of what platform you pick. I think you're understanding this backwards. I'm not aiming to port a desktop app to a mobile app, I'm aiming to choose a UI toolkit that works fine in mobile by default and requires tweaks in your app to make it work in desktop (rather than choosing a UI toolkit that works fine in desktop by default but requires tweaks in your app to make it work in mobile).

This is a pipe dream and will remain one.

  Why? The web does it pretty easily.

    The web? That's the opposite of what was requested here. Most websites look good on desktop but require tweaks to be seen properly on mobile. Not the other way around.

      > Most websites look good on desktop but require tweaks to be seen properly on mobile. This is a weird take. Most web browsing these days is done on a mobile device. Even HN, with its table-based layout, works completely fine on a phone, because it has to- at some point someone put in the minimum to make it work nicely on a mobile screen (basically one meta attribute and perhaps a few CSS media queries). You can build a single web app (without detecting the user's device and switching versions) that scales from the smallest phone to a theater screen thanks to media queries and CSS. It's even a best practice manifested as "Mobile First Design" that it's better to build a mobile web app first, and get that right, then use responsiveness and media queries to iterate that into a desktop version. I personally think this is a debateable proposition, but it seems weird to state that "most look good on desktop but require tweaks to be seen properly on mobile", when it is in fact the case that most websites and apps are designed for mobile first. The web is fully capable of delivering an appropriate experience across all form factors, on websites and on web apps. If the web can do it, I don't think it's a pipe dream to capture that capability in a non-web native/cross-plat UI framework designed to do what the web is already doing today. Admittedly CSS is big and crazy and insanely powerful because it has to be, and is probably overkill outside of HTML (though I've seen some UI frameworks approximate it), but a middle ground is definitely possible if you think creatively about it. Now "possible" and "it exists" are two different things- that's why the web is such an alluring platform: It is probably the single most powerful and flexible user interface framework (in a sense) ever designed.

  It is MAUI.

  So Avalonia is built on top of Skia which is Google’s portable 2D rendering engine. So in theory it is as cross platform capable as Chrome/Electron without all the overhead that html brings. Brilliant play, imho. Now, as long as Apple doesn’t manufacture a reason to ban apps based upon it…

    Skia is also used by Android, Flutter and Xamarin, among others.
