ForeUI is a handy UI prototyping tool. It can rapidly create static or interactive, skinnable UI prototypes of your website or software. You can use ForeUI to:

* Draw the GUI in your mind and make others understand quickly.
* Make runnable mockup of website or software to collect feedback from potential users.
* Perform usability testing before releasing the beta version.
* Generate the schematics that can be inserted in the design documents.

Features

* Various UI Themes

ForeUI provides various UI themes for mockups (why?), including Hand Drawing, Wireframe, Windows XP and Mac OS X themes. The UI themes cover high, middle and low fidelity degrees. You can switch the UI themes at anytime, that means you can design the UI with on theme and preview it with other themes later.
* Interactive Simulation

You can run your prototype in your browser! You can define the behavior of each element, so that your prototype can provide real user experience. The simulation is DHTML based, you can also upload the simulation to your website and make it work as part of your site. The simulation is also skinnable, the look and feel of simulation will be the same with current UI theme of the prototype. Here are two interactive simulations generated by ForeUI: Website Simulation & Installer Simulation.
* Customized Element

You can create your own element and keep it for future usage. The customized elements can have their own behavior, that means you can create some functional widgets.
* Slide Show and PDF Exporting

ForeUI support editing multiple plots at a time. Each plot can contain multiple pages, you can view your design with slide show, export your design to PDF file, or export the pages to PNG, JPG, BMP, GIF and WBMP images. You can also make some annotation on your slide show.
* Rumple Effect

Rumple effect is a special feature of ForeUI. It can create the rumple on the plot and make the mockup more like a design on the paper. What's more, you can decide the magnitude of the effect as you need.
