Rollbase is a on-demand application development platform for business users that uses point and click, drag and drop tools in a standard web browser. The service is designed for users who aren’t programmers. There are a few pre-built applications for Rollbase in the Application Directory - including bug tracking, customer relationship management, and a document library.

The platform is relatively easy to learn and simple to start development. I signed up for the 60-day trial and was designing an application in minutes. There is a video demo of the Rollbase Beta posted on their site.

There is currently no pricing posted on the Rollbase site, but the service competes with the Saleforce.com platform so expect pricing to be inline.
