A wireframe is a simplified representation of a screen or interface that focuses on structure, content hierarchy, layout, and functionality before detailed visual styling.
A wireframe may show navigation, content sections, controls, forms, tables, and primary actions using simple shapes and placeholder content.
The goal is to make structure visible.
A mockup normally includes more realistic visual styling. A wireframe stays focused on layout and hierarchy.
A wireframe can be static. A prototype simulates interaction or flow.
Wireframes can become clickable prototypes when linked together.
Realistic content often reveals layout and hierarchy problems earlier.
If visual details dominate the conversation, the artifact may no longer serve its purpose.
A good single screen can still belong to a broken journey.
A wireframe asks: before we style this, is the information and functionality arranged in the right way?
