Very simple and affordable wireframing tool. Works great for both large and small business. Allows multiple users to easily collaborate on a design, and to create projects. Review collected by and hosted on G2.com.
Ironically, the UI for building a prototype is not overly user friendly. All of the icons are very small and thin, and are often hard to navigate through. A lot of the tools are also initially hidden, so it takes a bit of time to navigate through the interface and find what you're looking for. Review collected by and hosted on G2.com.
