Best Prototyping Software

Prototyping software is used to create incomplete or preliminary versions of software and applications. The prototype simulates the final product in order to test, document errors, and deliver feedback. Development teams will use prototyping tools to increase the speed at which they build, test, and iterate their program without the need of developers. The two commonly accepted types of prototypes are horizontal and vertical. Horizontal prototypes are used mainly for user interface testing, while vertical prototypes are more complete and simulate a greater number offunctions. These tests will provide teams with feedback on a variety of components for development and product teams to utilize prior to an official launch. There is crossover between prototyping products and wireframing products, but wireframing tools produce preliminary outlines with significantly less fidelity and functionality.

To qualify for inclusion in the Prototyping category, a product must:

  • Provide tools for creating interactive models of final applications
  • Possess libraries with frameworks, workflow templates, and symbols
  • Provide interface creating and editing tools
  • Possess requirements management tools
  • Possess feedback and communication components
