Mockup vs. prototype

Mockup vs prototype

Brief definitions

Any design of a product, app, website etc. relies heavily on the ability to visualize ideas before they are brought to life. This takes the form of mockups and prototypes. And even though sometimes they are used interchangeably, understanding their distinct differences is essential to effectively communicate and manage stakeholders’ expectations.

A mockup is a static, high-fidelity representation of the design visual elements. It aims to showcase the aesthetics, including the color schemes, typography, and images without providing any interactive features.

On the other hand, a prototype is a working model of a design that allows user interaction. With the help of a prototype tool, designers can create interactive elements, demonstrating the flow and functionality of the design.

Differences between mockup and prototype

When comparing mockup vs prototype, their individual purposes become clearer. While a mockup mainly provides a visual illustration of the final product, a prototype goes further to illustrate the functionalities and interactive elements of the product.Therefore, they follow a sequential order, each being addressed at a particular phase of the design process.

Mockups are important because they help in finalizing the visual aspects and securing stakeholders’ approvals. They're used to show stakeholders what's planned, get their thoughts, and eventually win their support. At this stage, small tweaks or even big improvements can still be made.

On the other hand, prototypes are vital in usability testing, allowing the design team to identify and rectify issues before moving to the development stage. They can be tested not only with the internal team, but also with users. In this way, the design can still be refined before it goes into development.

Mockup vs. prototype. A comparison.

We can consider a few elements that make the two different from each other: purpose, fidelity, functionality, resources needed, and the time spent to develop them.

A mockup is a static, visually detailed model showing the design's aesthetics. It's high-fidelity, but not interactive. It requires resources like images and color schemes and takes less time to produce than a prototype.

In contrast, a prototype is always interactive, showing the design's functionality and the experience the user will have. It can vary in fidelity, from low-fidelity to high fidelity prototypes,  and needs a prototype tool to create. It’s time intensive, meaning that it takes longer to create because of its emphasis on user experience. This means the prototype must mimic the functionality and interaction of the final product, requiring careful planning, design, and testing of each element and pathway.

After a prototype is produced, it has to undergo usability testing to identify problems and potential improvements.

Where does the confusion come from?

The terms 'mockup' and 'prototype' are often misused in conversations, leading to some confusion among designers and stakeholders alike.

The main reason for the mix-up comes from the interactive element. A high-fidelity mockup, rich with design details, can sometimes be mistaken for a prototype due to its comprehensive appearance. The key distinction lies in the functionality - while a prototype allows user interaction, demonstrating the flow and response of a design, a mockup remains a static, visual representation only. Understanding this difference is crucial to clear communication and efficient design process management.


Understanding these nuances, and the distinct value each provides, is essential for effective design work. As we navigate the complexity of the design process, the efficient use of both mockups and prototypes helps us translate abstract ideas into concrete, user-friendly products that can be presented to stakeholders and users.
