What is ForeUI?

With ForeUI GUI Prototyping Tool, you'll find an easier way to share ideas, review design concepts, collect feedback before committing hours, and measure usability in a meaningful way. Featuring the ability to skin your prototypes in a variety of popular themes, ForeUI GUI Prototyping Tool lets you test out several looks and feels to get things right before you engage in any heavy duty coding. ForeUI is a user-interface prototyping tool that allow you to create mockup/wireframe/prototype for the application or website in your mind. A prototyping tool is one that creates the prototype or mockup of the actual application you are making.

Featuring the ability to skin your prototypes in a variety of popular themes, ForeUI GUI Prototyping Tool lets you test out several looks and feels to get things right before you engage in any heavy duty coding. ForeUI is a desktop-based prototyping tool that works by dragging and dropping pre-designed UI elements onto a blank page. These elements are organised into Prototyping - Tools for Mockups, Wireframe and Prototypes. ForeUI is a UI prototyping tool, designed to create mockups, wireframes and prototypes for any application or website. With ForeUI, the prototype project will be skinnable, since the style of the prototype can be changed by switching the UI theme.

ForeUI is an easy-to-use UI prototyping tool, designed to create mockup / wireframe / prototypes for any application or website you have in mind. With ForeUI, your prototype project will be skinnable, since you can easily change the style of your prototype by simply switching the UI theme. You can even design the behavior of prototypes by defining intuitive flow charts to handle specific events. Your prototype can then be exported to wireframe images, PDF documents or HTML5 simulation. All of these make ForeUI a very useful productive tool for sharing ideas, reviewing design concepts, collecting feedback and usability testing.

What’s more, the HTML5 code generated by ForeUI has very high performance and could directly communicate with the back-end web services. So it is possible to use ForeUI as an IDE for developing front-end of real web applications (some examples here).

ForeUI works in Windows, Mac OS X, and Linux systems.

What do our customers say?

I just had to take a minute to tell you what a great job you guys did on ForeUI. I’ve been writing software for 20 years and have used thousands of software apps for building all kinds of software and your product for building out prototypes and wireframes is about the easiest and the nicest to use that I’ve ever seen. Bravo to you guys and we are definitely going to purchase this for our company or I will purchase it myself.

— Chris Wright, Senior Software Engineer at Avolve Software Corporation

I’m stunned at how easy it is to use the program. Literally within 15 minutes I had created a sample page with links, logic, graphics, the works. A brilliantly designed piece of software. It’s going to take no more than a couple days to get the majority of our proposed site design mocked-up so we can begin making the tough decisions on key functionality, only this time we’ll have a realistic prototype to use as the basis for our decisions. What a difference! I can already see huge benefits in getting a clean, comprehensive design upfront, not to mention greatly minimizing or eliminating late-stage rework. Without question this will be the most important tool for streamlining our development cycle.

— Tim Weichman, Director of Online Development at Life of Learning Foundation

ForeUI provided us with fast and easy wire-framing capabilities well beyond any other tool we evaluated. The user audience that made use of the tool are not usability professionals, but the user-friendly interface and expansive functionality of ForeUI allowed them to rapidly pick up the tool and make it work for their products in record time. ForeUI comes with a wide range of styles and functionality that are readily available, but most importantly, it gives you the ability to create wireframes and workflow that is quickly digestible to many audiences. This tool has become critical to the successful integration of user experience into our Agile process. Thank you ForeUI!

— Deb Brown, User Experience Architect at Iron Mountain Digital

ForeUI is an incredibly powerful tool for rapidly realizing a wide variety of interactive projects. I’ve used it successfully to design and validate a number of product concepts and will continue to do so because it works so well. There are few, if any products that match ForeUI’s extensive capabilities at any price. What’s more, ForeUI is frequently updated with new features being introduced as a result of direct user feedback. I look forward to each and every release!

— Ari Feldman, Director of User Experience at AdMeld, Inc.

You have an incredible product. The reason I did not register is “not” because of the ForeUI product. It’s because of me. I am not really doing anything in the website development area that requires regular usage of such a fine product. I was just dabbling, more for the fun of it. If I were going to become seriously involved with that kind of responsibility, I would buy it. Quite honestly, after experimenting with just about every competitive product, I think that ForeUI is the easiest, and yet, most powerful UI prototyping tool that I have ever used.

— David Ellenbogen
