The Uno Platform is an Open-source platform for building single codebase native mobile, web, desktop, and embedded apps quickly. It allows C# and WinUI XAML and/or C# code to run on all target platforms, while allowing you to control every pixel. It comes with support for Fluent, Material, and Cupertino design systems out of the box. Uno Platform implements a growing number of the WinUI APIs, such as **Microsoft.UI.Xaml** to build your UI, and WinRT to get cross platform access to non-UI APIs (sensors, file system, devices, etc...), to enable WinUI applications to run on all platforms with native performance. It allows you to leverage your familiar IDE and enhance your productivity with our [XAML/C# Hot Reload](xref:Uno.Features.HotReload) features and [Hot Design](xref:Uno.HotDesign.Overview), to design and run your application on iOS, Android, macOS, Windows, Linux, and WebAssembly. Visit [our documentation](xref:Uno.Documentation.Intro) for more details. # Getting Started See the complete [Getting Started](https://platform.uno/docs/articles/get-started.html) guides for starting with Visual Studio, Visual Studio Code, or JetBrains Rider.
