What are the differences between Crosslight Form Builder and Xamarin Form?

Crosslight Form Builder is designed for developers to easily create rich data form targeting multiple platforms with a set of simple attribute-based metadata. Crosslight Form Builder is built with MVVM design pattern for the best separation of concern where the data input is provided in the model and ViewModel, which are then bound to the View in loosely-coupled manner. This means that Form Builder is not designed to unify the heterogenous views across different platforms which will cause a lot of issues and limitations.

Xamarin Form, in the contrary, is built with Unified View pattern which mixes UI definition, logics and input together. Since it unifies the views across all platforms, it can only provide features that conform to the lowest denominators of all platforms. This means that developers cannot leverage the unique UI features available in a particular platform. Compared to Crosslight, Xamarin Form falls short of architectural design and feels like an incomplete solution. It's a quick solution only for small projects and targeting novice developers who don't concern much on architectural aspects such as maintainability, extensibility, and scalability in the long run.

Unlike Xamarin Form, Crosslight Form Builder is only a subset of feature available in Crosslight. There are much more features that Crosslight has to offer, including a comprehensive solution for building enterprise-class mobile apps for iOS, Android, Windows Phone and Windows 8. It includes not only powerful frameworks, but also tons of gorgeous UI components, data access components, and best tooling support.
