Prototyping tools are software applications that help designers and developers create early models of products, such as websites or mobile apps. These tools allow users to visualize and test ideas quickly, making it easier to gather feedback and make improvements before final development. Common features include drag-and-drop interfaces, interactive elements, and collaboration options. Some popular prototyping tools include Figma, Adobe XD, and InVision. These tools cater to different needs, from simple wireframes to high-fidelity prototypes. By using prototyping tools, teams can streamline their design process and enhance communication, ultimately leading to better end products.
