📖 About

Avalonia is a cross-platform UI framework for dotnet, providing a flexible styling system and supporting a wide range of platforms such as Windows, macOS, Linux, iOS, Android and WebAssembly. Avalonia is mature and production ready and is used by companies, including Schneider Electric, Unity, JetBrains and GitHub.

Considered by many to be the spiritual successor to WPF, Avalonia UI provides a familiar, modern development experience for XAML developers creating cross-platform applications. While Avalonia UI is similar to WPF, it isn't a 1:1 copy, and you'll find plenty of improvements.

For those seeking a cross-platform WPF, we have created Avalonia XPF, enabling WPF applications to run on macOS and Linux with little to no code changes. Avalonia XPF is a commercial product and is licensed per-app, per-platform.
