A high-fidelity prototype is a detailed and interactive model of a product that closely resembles the final design in terms of functionality, aesthetics, and user interface. It often includes advanced features such as clickable elements, animations, and realistic content, providing a comprehensive user experience that allows stakeholders to interact with the product as they would with the finished version. In contrast, a [[low-fidelity prototype]] is a simplified representation of a product, typically using basic sketches or [[wireframe prototype|wireframes]] to convey the overall structure and flow without focusing on detailed design elements or interactivity. Low-fidelity prototypes are usually quicker and less expensive to produce, making them ideal for early-stage conceptualization and iterative feedback, while high-fidelity prototypes are used in later stages to refine details and test usability more accurately.
