Skia Rendering

Skia Rendering

Avalonia leverages SkiaSharp to render the UI directly. Unlike other cross-platform .NET UI frameworks that simply wrap native controls into a limited API, Avalonia gives developers direct access and full control of rendering behaviour.

This approach ensures your application's UI is responsive and visually consistent across every platform, helping to eliminate platform-specific rendering issues.

No Dependency on .NET MAUI

No Dependency on .NET MAUI

Create beautiful mobile apps for iOS & Android

Avalonia eliminates dependence on .NET MAUI or Xamarin.Forms, freeing your team from fragile, lowest common denominator abstractions.

Avalonia leverages .NET iOS and .NET Android but isn’t tied to them, with internal experimentation exploring removing these dependencies entirely to unlock even greater performance.
