A WYSIWYG, or “What You See is What You Get” App Builder, helps you build the UI visually, as opposed to writing code. Besides dropping components on a design surface, you can create custom layouts for your screens. And then change the position and presentation of each component inside the layouts.
With a WYSIWYG, you can review the final look and behavior of the app even before you generate code. And when you generate, you see it pixel-perfect in the final app. A WYSIWYG editor makes it easier for product managers, developers, and designers to work together. This can avoid costly and wasteful iterations in the final app by catching errors early.
