Qt is described as 'Cross-platform application framework that is widely used for developing application software that can be run on various software and hardware platforms with little or no change in the underlying codebase, while having the power and speed of native applications' and is a very popular app in the development category. There are more than 50 alternatives to Qt for a variety of platforms, including Windows, Linux, Mac, Android and Self-Hosted apps. The best Qt alternative is GTK, which is both free and Open Source. Other great apps like Qt are Flutter, Electron, Tauri and React Native.
GTK is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK is suitable for projects ranging from small one-off tools to complete application suites.
GTK+ is more portable (including embedded systems) and includes wrappers to more languages than Qt.
Build apps for any screen. Flutter transforms the app development process. Build, test, and deploy beautiful mobile, web, desktop, and embedded apps from a single codebase.
If you can build a website, you can build a desktop app. Electron is a framework for creating native applications with web technologies like JavaScript, HTML, and CSS. It takes care of the hard parts so you can focus on the core of your application.
GUI design isn't just for making web pages.
Electro is a completely different kind of software. It's like comparing a car to a bicycle, for real.
It is very ineficient compared to qt and not as crossplatform
Tauri is a toolkit that helps developers make applications for the major desktop platforms - using virtually any frontend framework in existence. The core is built with Rust and the CLI leverages Node.js making Tauri a genuinely polyglot approach to creating and maintaining...
React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about — learn once, write...

wxWidgets is a C++ library that lets developers create applications for Windows, OS X, Linux and UNIX on 32-bit and 64-bit architectures as well as several mobile platforms including Windows Mobile, iPhone SDK and embedded GTK+.
Mono is a free and open source project led by Xamarin (formerly by Novell and originally by Ximian) to create an Ecma standard compliant .NET Framework-compatible set of tools including, among others, a C# compiler and a Common Language Runtime.
Kivy is a Python library for development of multi-touch enabled media rich applications. The aim is to allow for quick and easy interaction design and rapid prototyping, while making your code reusable and deployable.
Svelte Native is a new approach to building mobile applications using NativeScript. Where other JavaScript mobile development frameworks like React Native and NativeScript-Vue do the bulk of their work on the mobile device, Svelte Native shifts that work into a compile step that...
Avalonia is a WPF-inspired cross-platform XAML-based UI framework providing a flexible styling system and supporting a wide range of platforms including: Windows, Linux (desktop & embedded), macOS, Android, iOS and Browser.
not well maintained, the documentation that says to be for version v11 is the same as for version 10, and the actual packages are completely different. NOT RECOMMENDED
