Fabulous is a modern declarative UI framework for crafting cross-platform mobile and desktop apps in .NET. It aims to bring you a great development experience and confidence in your code by combining an expressive UI syntax, the simple & robust Model-View-Update (MVU) architecture, and functional programming.
Fabulous aims to provide all the tools to let you create your own mobile and desktop apps using only F# and the Model-View-Update architecture (shorten to MVU), with a great F# DSL for building dynamic UIs. The combination of F# and MVU makes for a great development experience.
Note that Fabulous itself does not provide UI controls, so you’ll need to combine it with another framework like Xamarin.Forms, .NET MAUI or AvaloniaUI.
