6. Flutter

Flutter has gained significant traction as an alternative to Eclipse RCP, particularly for building cross-platform desktop applications with a focus on mobile-first experiences. Developed by Google, Flutter offers developers a reactive framework and a rich set of UI components for creating visually appealing and performant applications using a single codebase written in Dart.

Pros: Flutter allows developers to build applications for multiple platforms, including desktop, web, and mobile, using a single codebase. Its Hot Reload feature enables fast iteration and improves developer productivity. Flutter also provides excellent performance and a customizable UI toolkit.

Cons: As Flutter is a relatively new framework, its ecosystem may not be as mature compared to some other alternatives. Additionally, the lack of native UI components may require additional effort to achieve platform-specific UI designs.

7. Avalonia

Avalonia is an up-and-coming alternative to Eclipse RCP, providing developers with a cross-platform framework for building desktop applications using XAML and C#. Inspired by Windows Presentation Foundation (WPF), Avalonia offers a similar programming model and a rich set of UI controls, enabling developers to create modern and responsive applications for Windows, macOS, and Linux.

Pros: Avalonia seamlessly integrates with the .NET ecosystem and supports XAML-based UI design, making it an attractive choice for C# developers. It offers good performance, supports styling and theming, and provides a familiar development experience for those familiar with WPF.

Cons: As Avalonia is still relatively new, its community and ecosystem may not be as large or mature compared to some other alternatives. Additionally, the learning curve for Avalonia may be steep for developers who are not familiar with XAML or the .NET framework.

8. Gtk#

Gtk# is a powerful competitor to Eclipse RCP, providing developers with a cross-platform framework for building desktop applications using C# and the Gtk toolkit. With its extensive set of UI controls, support for internationalization, and seamless integration with the Mono framework, Gtk# offers developers a flexible platform for creating native-looking applications on Windows, macOS, and Linux.
