Uno Platform is an open-source (Apache-2.0) .NET framework for building native mobile, web, desktop, and embedded applications from a single C#/XAML codebase using the WinUI 3 API surface. It includes UI controls, themes, Hot Reload, and AI-powered tooling (MCPs, visual designer) for modern .NET workflows.

Use cases

build a cross-platform app from one c# codebase
reuse winui xaml skills to target ios android and web
create a webassembly app in c#
build a desktop app for windows mac and linux with .net
port an existing winui library to mobile and web
design ui in figma and import to xaml
develop embedded linux applications with c# and xaml

When to choose

your team knows C# and XAML and wants one codebase across mobile, web, desktop, and embedded
you want WinUI 3 API compatibility with pixel-perfect rendering via Skia
you need enterprise-grade, actively maintained cross-platform .NET tooling with Hot Reload and AI-assisted design

When to avoid

you prefer native platform languages like Swift or Kotlin for maximum platform fidelity
you need a lightweight JavaScript/TypeScript web-only framework
you want a fully free toolchain including all AI Studio features, since some Studio tooling is commercial
