Justinmind Prototyper is an authoring tool for software prototypes and high-fidelity website wireframes. It was created by Justinmind and is currently on version 5.1. It offers capabilities typically found in diagramming tools like drag and drop placement, re sizing, formatting and export/import of widgets. In addition, it has features for annotating widgets and defining interactions such as linking, animations, conditional linking, calculations, simulating tab controls, show/hide elements and database simulation. There is support for high-fidelity simulation of Rich Internet Applications. Justinmind Prototyper can then generate HTML prototypes and Microsoft Word specifications.
High-fidelity Prototyping 
The program creates high-fidelity prototypes a step before the first version of a mobile app or website. The prototype can be used for show reels and testing purposes. Justinmind Prototyper can be used to create prototypes and simulations of software without any coding, thus allowing non-programmers to be involved in the project.
Usability testing 
It can be used for remote testing using Justinmind Usernote, which allow users to navigate through the prototype remotely. Users can also create comments over specific elements in the prototype in order to give their feedback. The application also supports the integration of analytic tools like Google Analytics, WebTrends, ClickTale, UserTesting and others to conduct real-time remote testing.
In 2012, Justinmind was awarded with the Best Application Award at the EclipseCon 2012 
In 2011, Justinmind was awarded the second prize of the Eclipse Community Award at the EclipseCon 2011 in Santa Fe, California.
