One of the most significant steps in the designing process, a prototype is a temporary sample version of the final product. As the final launch requires relevant investment in terms of time and money, a prototype is used for testing purposes before the final launch. A website prototype is an interactive demo of what a website will look like when it is finally launched. It allows its users the freedom to navigate from one page to another and access its drop-down menus and various other functions. A design prototype can be a paper sketch or digital or HTML prototype. Some examples of specialized prototyping tools are Axure, Blasamiq and Mokingbird.
