Applications can be built by using the tools in Visual Studio on Windows, including XAML and C#, and run on iOS, macOS, Android, Windows or in WebAssembly in a web browser.[5] A plug in for Microsoft Visual Studio is available from Microsoft's Visual Studio Marketplace,[6] VS Code Marketplace,[7] or JetBrains Rider Marketplace.[8] In addition to traditional IDEs, Uno Platform also offers an MCP server compatible with CLI environments and AI agents such as GitHub Copilot CLI, OpenAI Codex, Google Antigravity, and Cursor[9]. The community surrounding Uno Platform open source project comes together at its annual conference UnoConf.[10]
Uno Platform is an open-source project sustained by a support model like Red Hat’s[11] and via revenue from its commercial product, Uno Platform Studio, for which it raised a seed round.[12] Microsoft and Uno Platform announced official collaboration on maintaining .NET for iOS and .NET for Android GitHub repositories, as well as co-maintenance of SkiaSharp repository.[13][14] Microsoft lists Uno Platform as one of the alternatives to its own development stack.[15][16]
