Top Cross-Platform Desktop App Frameworks & Tools

Cross-platform software development is the need of the hour because of increasing demand for cost-efficient and short-timeline software projects. Such development process saves lots of efforts and allows writing a single codebase to create apps for multiple platforms.

In this post, we’re showcasing the 9 best frameworks and toolkits for coding cross-platform desktop software.

1. Haxe

As an open-source, high-level, and multi-platform programming toolkit, Haxe‘s single code-base creates applications or games for numerous target platforms. As a compiler, it compiles the source code for various desktop platforms, and the compilation is done source to source, i.e. its compiler produces equivalent source code in different language(s) for different platform(s).

It’s a full pack of a language, a compiler, a set of libraries, useful tools, and Haxe-based frameworks or tools.



  • It’s much faster than other similar compilers like Flash or Flex
  • Its bytecode is much faster than the equivalent produced by others
  • It’s a simple language allows the programmer to go as far as they like
  • Its platform can communicate smoothly with other platforms using ORM

Cons: Programs with native AS3 libraries are not yet fully supported by Haxe. Beside this, debugging difficulties increase after language translation of the source code, hence building something with Haxe requires high coding standards.

2. Electron

Initially built for the Atom code editor, Electron is an open-source framework developed by GitHub. By using the latest Node.js, it allows developers to write cross-platform desktop user interfaces with popular web technologies: HTML, CSS and JavaScript. It’s used by companies like Microsoft, Facebook, Stack and Docker.



  • It relies entirely on web standards that almost every web developer already knows, allowing them to write desktop software
  • It allows developers to focus on the core functionality of the applications by already taking care of the hard parts in software development
  • For desktop apps, it provides various core functionalities like auto-update, crash reporter, installer creator and system-specific features

Cons: No built-in MVC is provided by Electron, and platforms for Chrome are not fully supported as yet. Beside these, it’s also not as feature-rich or mature as NW.js.

3. NW.js

NW or Node Webkit allows developing cross-platform software using modern web technologies like HTML, CSS3 and JavaScript, including WebGL. It provides support for all Node.js APIs and most of third party modules, and lets you create apps for Windows, Mac OS X and Linux. This framework is a complete package for web developers interested in creating desktop applications using web technologies.



  • It has an impressive list of demo applications and video games
  • It provides great community support with easily searchable answers
  • Some of its functions are more feature-rich and mature than those of Electron

Cons: Some hard work features that are available in Electron, such as auto-updater and crash-reporting, don’t comes built-in with NW.js. That said, building with NW.js requires more efforts and extra modules – unlike other solutions.

4. 8th

8th lets developers write code and produce applications for various target operating systems including Windows, Mac OS X, Linux, Raspberry Pi, Android as well as iOS. Its primary focus is providing cross-platform compatibility as well as security in the final software products or distributions.



  • It comes with support for various essential libraries, which minimizes the dependency on external libraries
  • It lets you add features or fix bugs in just one place, and the changes are automatically updated on all the supported platforms
  • It provides enhanced protection by packing the applications in an encrypted container, making it tamper-resistant as well as difficult to crack

Cons: Business applications are the primary focus of this framework, and so far less support is provided to games. Besides, it is very costly, as it requires you to opt for its paid subscriptions for its full functionality.

5. B4J

B4J is more of an IDE than a cross-platform framework for developing applications that run on Windows, Mac OS & Linux systems and ARM boards (like Pi) as well. This solution lets you write code in B4X language, a modern version of Visual Basic. Your application is built for all the supported platforms and per people’s remarks, they work pretty well on the popular desktop platforms.



  • It builds apps with more performance and less overhead in mind
  • Its IDE is more like Visual Studio, allowing VB developers feel as at home
  • It also allows building web apps wherein business logic resides at server-side

Cons: This framework doesn’t provide full support for an obfuscator. Though very popular in the past, Visual Basic is not as popular as Java & other languages nowadays, and finding Visual Basic developers might be a tough task.

6. Kivy

Kivy is an open-source Python GUI framework to build multi-touch applications for desktop as well as mobile platforms. Using this framework, software using the same code can run on all the supported platforms, i.e. Windows, Mac OS X, Linux, Android and iOS. These cross-platform apps are coded in Python, but their GUI is built using the Kivy APIs which provides various layouts and widgets.



  • It provides built-in graphics library for creating rich UIs
  • It has an intermediate language to design custom widgets easily
  • It claims to give better performance than HTML/CSS/JS applications

Cons: The Kivy framework needs large amount of disk space for the development environment, and works or builds more smoothly on Linux development platforms. Besides this, Kivy requires a few minutes to start up on some devices.

7. Xojo

Xojo is a programming environment available for Windows, Mac OS X and Linux. With its Xojo IDE, it provides an easy-to-use, drag-and-drop UI builder, and its own language for coding your application. The IDE also allows testing the app immediately, and when it’s ready, it converts this app to run on multiple platforms.



  • It provides support for building apps for desktop, web, iOS and Pi
  • It supports over 40 built-in UI components that work on multiple platforms
  • It offers built-in support for graphics, database servers and various protocols

Cons: Sometimes, dealing with databases in Xojo is difficult and the programmer has to install some additional tools to facilitate the same. Moreover, the long term usage of its IDE asks for a commercial license, that’s not free, sadly.

8. Enyo

Enyo is an open-source JavaScript framework, like Electron, that allows developers to create native-quality apps for desktop, mobile, and TV. Enyo can run across all the relatively modern and standard web-based environments. It’s battle-tested and comes with a beautiful cross-platform UI toolkit for creating rich user interfaces.



  • It’s an all-JavaScript framework, providing customizable, choosable set of modules or components
  • It allows creating re-usable modules called components, and structures the whole project in these small modules
  • It creates a source map of bundled JavaScript for helping in debugging issues

Cons: This framework doesn’t provide support for IE8. Enyo is not as easy to develop as its competitors like Haxe and Electron, that can be owed to their bigger communities.

9. WINDEV Express

WINDEV Express is an IDE combined with framework for building cross-platform software. This framework allows developing applications for numerous platforms including Windows, Mac OS, Linux and more. It offers its own language called WLanguage to create the cross-platform apps using its IDE.

WINDEV Express


  • It provides its own integrated UI builder for creating rich user interfaces
  • It offers support for numerous databases including Oracle, MySQL and more
  • It allows using multiple modern UI features such as ribbons, workflow controls

Cons: WINDEV is more complicated than other frameworks because of its French releases and the incomplete translation of guidelines for every feature.
