DataMashups.com offers developers a new approach to develop web applications. The hosted service offers an integrated development environment to rapidly create mashups and web applications with limited or no need for server side code. The service is based on the open source AppliBuilder - a AJAX builder tool.
i.e Create mashups and web applications using our open source visual builder tool and integrated SQL.

AppliBuilder is a drag-and-drop visual mashup builder to create data integration applications using Ajax widgets and a variety of visual components. Using the power and convenience of AJAX, web components, and distributed data, AppliBuilder allows rich client applications to be developed faster than ever.

Developers can shift part of enterprise application development from complex server based applications, to more lightweight client-side applications using AppliBuilder. It provides tools for securing the client from unauthorized access to data as required, while allowing developers to quickly script necessary functionality including direct SQL access via client-side Javascript.

Application developers can sign up and use the free service once the service is launched . A paid premium service is also planned. Though only a demo version of the service is currently available.
