Our verdict on Uno Platform
Uno Platform is an open-source .NET framework for teams building mobile, web, desktop, and embedded applications from a shared codebase. Developers work in C# and XAML, or optional C# Markup, against an API compatible with WinUI 3. Targets include Windows, Android, iOS, macOS, Linux, and WebAssembly, making it relevant to teams that want to share application code across device types. It is a less natural fit for teams without C# experience or those seeking a framework centered on another language.
The framework offers both native platform rendering and Skia rendering, so teams have a choice in how interfaces are drawn across targets. Uno Toolkit provides controls and helpers, while Hot Reload supports a quicker development workflow. Figma design-to-code integration and WebAssembly browser deployment extend the workflow beyond native apps. Official tooling supports Visual Studio, Visual Studio Code, and JetBrains Rider. These capabilities offer breadth, but teams should assess their target platforms and rendering approach rather than assume every interface behaves identically everywhere.
The core framework is free and Apache 2.0 licensed; the paid subscriptions cover optional Uno Platform Studio tooling. Community is free and includes Developer Essentials, Hot Reload, Uno Toolkit, and unlimited MCP use. Pro costs $39 per user monthly or $390 annually, adding Hot Design, Studio App, 100 AI credits, and unlimited MCP use. Business costs $119 monthly or $1,190 annually per user, with Hot Design Previews, Hot Design Snippets, and 200 AI credits. A 15-day free trial is available. Teams primarily seeking a shared C# foundation can start with Community; those wanting Studio's additional design and AI tools should compare the paid tiers. Teams that do not need C# or cross-platform code sharing should consider a narrower fit.
