ForeUI is a prototyping tool that allows you to create static or interactive mockups for your software or website. It will ease the process of idea sharing, feedback collection, design documentation and usability testing etc.

You can use ForeUI to mockup quickly with hand drawn style, or create flat wireframe with certain colors and layouts, or implement high-fidelity prototype with complex behavior. You can change the style of prototype by simply switching its UI theme.

You can define the behavior of each element in the prototype without coding. All interactions will be defined with intuitive flow charts.

You can run the prototype as DHTML simulation in Web browser, which is very good for doing usability testing. Also you can export the prototype as image or PDF, which can be used in documentation.
