Developed by Microsoft, the .NET MAUI (multi-platform app UI) is an open-source framework to build native mobile and desktop applications for multiple platforms, including Android, iOS, macOS, Windows, and more, and that too, using a single codebase. Unlike the Xamarin forms, where developers have to maintain a separate codebase for each targeted platform.
