Why isn't there a way to make near-native desktop UIs that's similar in ease to browser and electron UIs?
it seems ridiculous that we have to embed an entire browser, meant for internet web browsing, just to create a cross-platform UI with moderate ease.
Why are native or semi-native UI frameworks lagging so far behind? am I wrong in thinking this? are there easier, declarative frameworks for creating semi-native UIs on desktop that don't look like windows 1998?
Ha! I'm partially looking at this issue in my bachelor's thesis.
It's not at all necessary to embed a browser, but it's really easy to transfer your web app to a "near native" experience with stuff like electron, ionic, cordova, react native or whatever other web stuff is out there. The issue is mostly that native APIs are complicated and relying on web views or just providing your own "browser" is a relatively easy approach.
Stuff like Flutter, Xamarin or .NET MAUI compile depending on the platform to native or are interpreted by a runtime. There's a study I use that compares Flutter to React Native, native Java and Ionic on Android and finds that unsurprisingly the native implementation is best, but is closely followed by Flutter (with a few hiccups), with the remainder being significantly slower.
The thing is. I don't think these compiled frameworks lag behind in any way. But when you have a dev team, that's competent in web development, you won't make them learn C#, Xaml, Dart or C++, just to get native API access - you'll just let a framework handle that for you because it's cheaper and easier.
Edit: To add some further reading. This paper and this one explore the different approaches out there and suggest which one might be "the best". I don't feel like they're good papers, but there's almost no other write up of cross-platform dev approaches out there.
Edit2: I also believe that the approach "we are web devs that want access to native APIs" may be turned around in the future, since Flutter and now also .NET offer ways to deploy cross-platforn apps as web apps. I'll get back to writing the thesis now and stop editing.

I remember thinking that Qt seemed like a really good approach that should be more widely adopted...until I actually had to use it.
Not that it's terrible; it's really not. But C++ is just not at all a good language for <s>anything</s> UI stuff.
QML on the other hand is awesome imo.
It's not that native UIs are lagging behind, there is a whole set of reasons.
TL;DR: browsers, as opposed to desktop apps, are stardartized - because they were originally designed to display and deliver text documents. We were never supposed to build complex application UIs on a web stack.
First, there is no standard way of making native UI on a desktop. Every OS uses it's own solution, while Linux offers several different ones. Browsers rely on a set of open standards developed specifically for the web, and even there not everything works exactly the same.
Second, browsers are designed to draw a very specific kind of UI through a very specific rendering mode - they run an immutable hierarchy of elements through layouting and painting engines. It works great for documents, but it becomes extremely unweildy for most other things, which is why we have an entire zoo of different UI implementations (crutches, most of them) for browsers.
On the desktop we often make a choice of what UI technology would fit best our purpose. For a game engine I would use an immediate-mode UI solution like ImGUI, for the ease of prototyping, integration and fast iterations.
For consumer software I might choose between something like QT or GTK for robust functionality, reliable performance, acessibility and community support. Mobile platforms come with their own native UI solutions.
For data-intensive UIs and heavy editors (e.g. CAD, video and music production, games) I might need to designan entirely new rendering pipeline to comply with users requirements for ergonomics, speed, latency etc.
It is also easy to notice that as a team or employer, it is often much easier to hire someone for web stack, than for native development. Simply put, more people can effectively code in JS, so we get more JS and tech like Electron enables that.
If you are interested in a single solution that will get you nice results in general, no matter the platform - you might see some success with projects like Flutter or OrbTK.
UI rendering in general is a deep and very rewarding rabbit hole. If you are in the mood, this article by Raph Levien gives a good overview of existing architectures: https://raphlinus.github.io/rust/gui/2022/05/07/ui-architecture.html
This is because each desktop operating system using a different graphics rendering engine—Quartz on macOS and X/Wayland on Linux, for example. In order to write an application that works on all major operating systems, you either need to use a graphics library that has already done the heavy lifting of calling the native frameworks under the hood or you have to do it yourself. Or you can use a web-based graphics library that has also already done that heavy lifting, with the added advantage that you can use languages like HTML, CSS, and Javascript to easily create visual elements. This is attractive when the alternatives like Qt are notoriously difficult to deploy and force you to use C/C++.
Quartz (usually referred to as Core Graphics) isn’t recommended anymore on Macs.
Developers should be using SwiftUI now, which is a completely different approach:
class HelloWorldView: NSView { override func draw(_ dirtyRect: NSRect) { super.draw(dirtyRect) // Drawing code here. guard let context = NSGraphicsContext.current?.cgContext else { return } // Set text attributes let attributes: [NSAttributedString.Key: Any] = [ .font: NSFont.systemFont(ofSize: 24), .foregroundColor: NSColor.black ] // Create the string let string = NSAttributedString(string: "Hello World", attributes: attributes) // Draw the string string.draw(at: CGPoint(x: 20, y: 20)) } }Here’s the same thing with SwiftUI:
struct HelloWorldView: View { var body: some View { Text("Hello World") .font(.system(size: 24)) .foregroundColor(.black) .padding() } }Quartz is a layer beneath SwiftUI or AppKit. SwiftUI is still using Quartz under the hood. The way you use Quartz directly from SwiftUI vs AppKit is a bit different, though still fairly similar. A more fair comparison of the SwiftUI code would be:
struct HelloWorldView: View { var body: some View { Canvas { context, _ in context.draw( Text("HelloWorld") .font(.system(size: 24)) .foregroundColor(.black), at: CGPoint(x: 20, y: 20) ) } } }Alternatively an AppKit solution (not using Quartz directly) would be something like:
class HelloWorldView: NSView { override init(frame frameRect: NSRect) { super.init(frame: frameRect) let text = NSAttributedString( string: “Hello World”, attributes: [.font: NSFont.systemFont(ofSize: 24), .foregroundColor: NSColor.black] ) let label = NSTextField(labelWithAttributedString: text) addSubview(label) } required init?(coder: NSCoder) { fatalError() } }In either AppKit or SwiftUI, you can access Quartz directly to implement custom views. However, most of the time the UI code you write in either SwiftUI or AppKit won’t call Quartz directly at all, but will instead be composed of built-in views, like
(NS)TextFieldor(NS)Button. Under the hood, SwiftUI is mainly just using the AppKit components at the moment, but provides a significantly nicer way to use them (especially in regards to layout and data synchronization).
Depends on your language.
I'm not too familiar with slinr or fybe but DearImGui seems like an odd one out here.
You mean like qt/qml? Due mind that even with those ui toolkits you will need to ship 'some' library. In case of QT it is not minimal at all. GTK can be more minimal but it still is significant.
Also there is tauri. Which doesn't ship a browser, but uses the platform native we view and is compiled while still having an amazing dev experience.
How is webview different from a browser exactly?
Electron apps ship their own chromium-based renderer, but 'webview' means the OS gets to use its own renderer. It's still a browser-like environment, but at least the OS can choose the most performant one.
Check out Tauri.app
I don't understand exactly how this is different. Is "WebView" not still very similar to a browser?
but.... but..... RUST!!!!!!!!!!!!!!!!!
q. e. d.
\s
It doesn't embed Chromium, it uses the native webview that already exists on the system. The average app I make using Tauri is less than 15MB, and being Rust on the backend you can go as low level as you like. The Tauri API provides access in your front end code to all the native APIs you can think of.
A genuinely cool and somewhat lean alternative to Electron!
Lots of other very pragmatic solutions also seem ridiculous.
Every problem is going to cost either clock cycles or highly skilled programmer time.
Currently, in the world, all eleven competent user interface element developers are occupied with more important tasks.
Until one of those eleven finds some extra free time, the rest of us get to slap electron into everything, and he thankful we can spread our atrocious CSS anti-talents to one more problem-space.
Who are these eleven? Didn't realize the number is so small. Who determines who they are?Turns out it was an exaggeration
I am, hopefully, exaggerating on the 11 count. I don't know the exact number, and likely no one does - but it genuinely is shockingly small, considering how critical usability and accessibility are to everyday use of code.
Anyone can study the principles of usability and accessibility, but the number of experts we have really is far too few, and I suspect it's is why we have so much reuse instead of innovation, right now.
basically this comes down to time and money. if you're a hobbyist, you have lots of options available, but they take time to learn and you probably already know html. if you're a professional, developer time is more expensive than cpu cycles and you probably already employ a web developer. unless there's a good reason, most people won't learn an entirely new GUI toolchain.
Plus, on average web developers earn less. So if you can create your desktop application with a web tech-stack, that saves you money as a manager, which in turn increases your bonuses: You're incentiviced to do that!
Really depends where you live
https://slint.dev/ has gotten there, IMO. They're working on a python binding and even to compile to android apps.
Check out qtquick, it's a bit clunky but capable
The painfully obvious solution is for these to open in a browser you already have.
The real question is how we got any portable solution to this problem in the first place.
To me problems are fundamentally economic and political, not technical. For example, the unique circumstances that led to a portable web standard involved multiple major interventions against Microsoft by antitrust regulators (in 2001, 2006, 2009, 2013, etc). The other tech giants were happy to go along with this as a way to break microsoft's monopoly. Very soon after, Google and Apple put the walls straight back up with mobile apps.
If you go back before HTML, OS research was progressing swiftly towards portable, high-level networked GUI technology via stuff like smalltalk. Unfortunately all of the money was mysteriously pulled from those research groups after Apple and Microsoft stole all the smalltalk research and turned it into a crude walled garden of GUI apps, then started printing money faster than the US Mint.
Whenever you see progress towards portable solutions, such as Xamarin and open source C#, React Native, or even Flutter, it is usually being funded by a company that lost a platform war and is now scrambling to build some awkward metaplatform on top of everyone else's stuff. It never really works.
One exception is webassembly, which was basically forced into existence against everyone's will by some ingenious troublemakers at Mozilla. That's a whole other story though!
I need that story
Check out kotlin compose multiplatform. Takes the Android declarative jetpack compose UI framework and makes it run cross platform. You get most of the modern UX conveniences from Android, can reuse libraries etc. Works with either JVM or compiling to native code too.
Avalonia is great. It's cross-platform, supports hot reloading, it's XAML based, so not too different from HTML, it's FAST, has IDE integration and can be styled to match any OS's native UI.
It's much easier to write an abstraction over one platform, an embedded chromium browser, than it is to write abstractions over several drastically different platforms. For most applications, the developers are satisfied with the performance and footprint anyway and see no value in maintaining a different application for the different platforms when it can all be written once with something like Electron.
Still, there are people out there trying to write cross-platform, native UI frameworks. For example, I believe that's what Slint is trying to do, although I've never tried it myself.
It depends on just how "cross-platform" you want to make it. If you came up with another standards-based UI framework that had the same cross-platform penetration of web browsers, then you'll have effectively reinvented the browser. For everything else, you can basically pick a maximum of two: cross-platform, native, and easy.
I'm not sure what you mean about embedding a browser - do you mean writing your UI in XAML? If so I wrote a whole blog post suitable for beginners and up on how to write a MAUI UI using only C# Creating MAUI UI's in C#
Never expected to see imgui mentioned in one sentence with flutter ngl
Why's that?
Haven't dabbled with them yet but I've heard of Avalonia and Compose.
There's https://redbean.dev/, but it's not quite what you mean.
It runs on the browser with a local host reference to a lua server with access to c libs.
