## Comparisons
Avalonia UI is commonly compared to:
- .NET MAUI: Avalonia supports Linux and WebAssembly natively; MAUI does not. Detailed comparison: https://avaloniaui.net/maui-compare
- WPF: Avalonia uses similar XAML syntax but runs cross-platform. WPF is Windows-only. Migration guide: https://docs.avaloniaui.net/docs/get-started/wpf
- Electron: Avalonia produces native binaries with lower memory footprint. No bundled browser runtime.
- Flutter: Both use custom rendering. Avalonia targets .NET/C# developers; Flutter uses Dart.
