Prototyping tools are software applications that help designers and developers create interactive models of their products before final production. These tools allow users to visualize and test ideas quickly, making it easier to gather feedback and make improvements. Common features include drag-and-drop interfaces, pre-built components, and collaboration options. Popular prototyping tools include Figma, Adobe XD, and InVision. Each tool offers unique functionalities, such as real-time collaboration or advanced animation capabilities. By using these tools, teams can streamline the design process, reduce development costs, and enhance user experience through iterative testing and refinement.
