Prototype

An interactive mockup used to test and demonstrate a design before build.

A prototype is a clickable simulation of a product, ranging from low-fidelity (linked wireframes) to high-fidelity (realistic, animated flows). It lets you test ideas with users, pitch to stakeholders, and catch problems before expensive development.

High-fidelity prototypes — for example built in Framer — can look and behave like the real product, making user testing and fundraising far more convincing.
