Creating mockups and prototypes is an essential part of any application development process. Prototypes help set clear expectations for a project and save time and money by avoiding costly reworks. You can also use mockups or prototypes when pitching an idea to investors. Software products in this category provide the necessary tools to build wireframes, mockups, and prototypes. These include tools to create diagrams, flowcharts, images and tools to add colors, logos, and text. Key features of these products revolve around drag-and-drop widgets, libraries of design templates, testing tools, the ability to design with others in real time and the ability to share prototypes with team members and get feedback from them.
