    Ask HN: Which cross platform desktop GUI to use instead of Electron?

    16 points tones411 | 15 comments | 14 Oct 25 08:03 UTC | HN request time: 0.8s | source | bottom

    Electron gets hate due to filesize and memory bloat. C++ gets hate for memory leaks. Rust with Tauri relies on a webview which could change versions underneath the app when the OS gets an update.

    Which language and cross platform desktop GUI framework checks the boxes for being lightweight in terms of filesize and memory usage, has native controls, supports accessibility and uses retained mode rendering, and works the same ten years from now as the day it was installed?

    If someone were to build an installable desktop app with buttons, checkboxes, inputs etc. (so not a video game) which language and GUI framework should they to use to please the memory and filesize conscious?

    Tk using the themed ttk widgets might meet your needs, not sure about accessibility though. Wxwidgets is also an option but can get weird with the native controls, not sure about accessibility there either.

    Java. JavaFX has native binding to the underlying platform.

    I always go for Qt for this(with C++ for bigger project and Python for lighter).

    There's also Delphi, which ticks all the nice boxes for UI requirements. But licencing is tricky there, not everything is available in community edition and more difficult to find support / developers for the project. Having said that, it's still great.

    Kotlin with compose multiplatform shaping up too, so something to test out if it matches your current requirements.

    The most obvious answer would be to use the OS's native UI widgets, e.g. in Windows maybe even Win32 widgets. With under 200 lines (!) of C/C++ code you get windows, buttons, text fields, lists, tables, whatever you need. The end result is an executable of size less than 8 kilobytes, and has been working last 20-30 years in the past, and most probably will work decades in the future.

    Besides, there isn't really "cross-platform GUI", because not every platform has same kind of widgets and behaviors.

    Honestly, I don't get the Electron hate. The majority of developers here on HN probably use VS Code as their editor, and that editor was made with Electron. For a lot of companies who don't have a desktop app as their main product, it simply isn't feasibly to have a dedicated Windows developer, a Mac developer, and a Linux developer, when you can do everything with one codebase.

    PWAs! Just use the browser. The safest, fastest option

    I came to mention this. I'm doing a Python/Qt project right now and I love it.

    Consider Compose Multiplatform and Kotlin Multiplatform

    A few other options to consider:

    - Lightweight local web server + web page combo

    - Native layer for each platform + shared business logic parts

    - Some game dev engine could also work - Unity, Godot..

    Qt? MAUI?

    I'm one of the developers of Slint[0], a framework the should be ticking all the boxes for stable, lightweight, and native-style UIs supporting accessibility

    I am very impressed with Slint, especially once you jump through the hoops to enable the skia rendering backend.

    I am using wails in one of my personal project currently. It's basically a combination of any frontend stack with go. File size is pretty minimal.

    So far, I have tried Qt directly with C++ and python bindings (pySide6, pyQt), where C++ is definitely the lighter option.

    If you consider python bindings, you could also look into JavaFX. It has the advantage of native images or the option of a fat jar containing all platform dependant FX modules. But the resulting files won't be small.
