Your Own Personal Application Server

Code On Time release introduces a built-in application sever in web apps created with Unlimited edition. Developers are creating modern user interface forms based on the data controllers using drag & drop and cut/copy/paste. Customized data controllers provide powerful REST APIs that allow extending web apps created with Code On Time to any platform supporting REST, JSON, JSONP, and XML.

See an example of HTML form that allows submitting data to the web app database without a single line of code. Learn how to create a native Windows Client for your web app. More examples covering development of cross-domain and embedded jQuery scripts are coming soon. It is now possible to create custom user controls that take a full advantage of data controllers with the help of jQuery.
