A clickable UX prototype is an interactive version of a product mockup that allows you to show its functionalities and the user’s navigation flow in practice. It is a high-fidelity prototype of a product, but with no backend. A visual design allows you to see how a given functionality works in the context of the entire product. You can then decide whether it makes sense to send it to developers for coding. The UX prototype can be treated as a standalone project, e.g. to prove that your innovative idea for a new product really works and is worth investing in. It can also be a step in the overall development process of a Minimum Viable Product, e.g. to iron out potential wrinkles and ensure the product sent for coding is exactly what your future users expect.
