Prototyping articles and design guides

A prototype's job is to settle an argument before it reaches production. These articles cover prototyping that's fast enough to throw away and faithful enough to test: interactive Figma flows, code prototypes when fidelity matters, and motion studies that prove an interaction feels right before anyone builds it. We focus on choosing the right fidelity for the question you're actually asking. Skip that step and you end up polishing a prototype nobody needed. My rule is simple: match the fidelity to the doubt. A rough clickthrough answers a flow question in an hour; save the pixel-perfect build for the interaction you already suspect is the real risk.
