Axure RP

Axure RP Software for prototyping and specifying websites and applications.

• It is possible to create common projects for several people to work on one prototype at a time.
• Drag-and-drop is supported.
• Elements can be grouped into templates, thereby making changes to several pages at once.
• RIA applications can be emulated with the program.

An interface specification generator is available.
