System and Method for Authoring New Lightweight Web Applications Using Application Traces on Existing Websites

Disclosed are embodiments of an invention for assisting a user with creating a customized web application from an existing web application. The embodiments use a first computer system to access an existing website. As a user performs a task on the existing website, a software application for a new website is authored by processor(s) on the first computer system and/or a second computer system in communication with the first computer system based on traced interactions between the user and the existing website. Additionally, a storyboard for the new website is developed. The storyboard will contain screens with both automatically-clipped and user-clipped content from the existing website. Navigation details for the transitions between the storyboard screens are provided based on the recorded interaction events. Once developed, the software application for the new website can be uploaded to a proxy server through which it can be accessed by another computer system (e.g., a mobile device) and used to perform the same or similar tasks on the other device.
