Prototyping is an indispensable part of the UI/UX design process. Where wireframes and sketches give both designers and stakeholders a sense of a product’s core functionality, and mockups offer a chance to get feedback on the visual design, interactive prototypes are a vital step because they allow designers to test the usability of a product’s various user interfaces, observe user interactions, and understand what issues need to be addressed before the final design is implemented in the final product.

UX prototyping tools can be as simple and low fidelity as pencil and paper. But most UI/UX designers incorporate a variety of software-based tools to create interactive prototypes—complete with complex assets, dynamic content, interactive elements, and animated graphics—without having to build the product using code. In fact, prototyping software has over the years become so sophisticated that different programs can now support a variety of templates across desktop and mobile apps as well as iOS and Android devices, allow for responsive and adaptive views, and enable collaboration and app integrations.

There is no one-size-fits-all prototyping software, which is why it’s not uncommon for UI/UX designers to use multiple tools on a project, or switch between prototyping tools depending on the demands of a project.

Why Prototyping Tools Are Crucial in UI/UX Design

Importance of tools for UI UX

The goal of prototyping is to test ideas and designs before they are baked into the final product. Prototyping tools enable UI/UX designers to see these ideas in action without having to involve developers. In fact, so advanced are today’s prototyping tools that most designers can use them to create high-fidelity prototypes with interactive components through the click of a button.

In addition to helping designers visualize their ideas, prototyping tools also allow them to test for usability and show stakeholders and clients how a website or platform responds to user interaction. Transitions, user workflow, interactivity, and layout can all be brought to life in prototypes, which allows stakeholders to offer input or express reservations before a project goes into production. In other words, prototypes can help companies save money by revealing and creating opportunities to address issues before they have been built into the end product. 

Tips on Choosing the Right UX Prototyping Tools

How to choose thee right tool

Every designer should ask themselves several key questions when choosing between different prototyping tools:

  1. What do you need the tool to accomplish?
  2. How much time are you willing to devote to learning how to use the tool? 
  3. Do you require features such as real-time collaboration? 
  4. What’s your budget?

Each of these questions is important because they can rule out certain tools. For example, if you need to build high-fidelity prototypes, then it would rule out popular tools like Balsamiq, which are best used for making quick wireframes. If you need a tool that can be quickly introduced with an easy learning curve, it might rule out powerful all-in-one tools like Adobe XD. And if you’re on a tight budget and can’t afford to buy product licenses for yourself or your team, it would rule out tools such as InVision or Axure RP. 

“Defining the goal of the prototype can help you think through the level of fidelity and functionality needed, which directly informs the choice of prototyping tool,” according to designer Fabricio Teixeira. “A common mistake designers make at the beginning of a project is to jump right into their favorite prototyping tool, without taking the time to meet with the team and discuss the context in which that prototype will be built, shared, and visualized. Changing your mind will be hard if you’ve invested many hours in building the first version of a prototype.”

10 Popular Prototyping Tools for UI/UX Designers
