Sigma Visual builder is a WYSIWYG tool for rapid Web application design and involved script programming. With this powerful builder, Web applications can be developed using only drag and drop, just like what you do in VB or Delphi. More than 35 common AJAX components, including Tabs, Dialog, TreeGrid, TimeLine, and many other Web GUI components are supported. Its rich client-side API works with any backend (such as PHP, .NET, Java, or Python) or static HTML pages. The generated application has wide cross-browser compatibility.
