Best prototyping tools to help UI/UX designers build better products

For some, failure isn’t an option. But for designers, it’s just part of the process. 

That’s because the journey to building a product that fits your target market establishes customer-centricity, and fills a specific user need can be long, complex, and iterative. Building a working model—a prototype—can help. With it, you can more quickly and easily confirm that a product or concept is viable, and that it does indeed solve a real-world problem. 

Let’s unpack what a prototype really is and explain the benefits of prototyping, then we’ll give you our take on the best prototyping tools for you and your business.

Tools listed in this article: 

• Balsamiq: Ideal for quickly sketching out wireframes with a drag-and-drop interface.
• Justinmind: An all-in-one tool for web and mobile app prototyping without code.
• Figma: Known for its collaborative features, allowing real-time design and prototyping.
• Marvel: A versatile platform for creating prototypes, with templates to speed up the design process.
• Framer: Offers extensive interactivity for prototyping, with the ability to import and export components and assets.
• Adobe XD: A comprehensive tool that integrates with other Adobe products and supports a range of design needs.
• Origami: A tool for creating highly detailed prototypes, particularly for Apple devices.

• UXPin: Known for its high-fidelity prototypes that aim to bridge design and development.

By definition, a prototype is an early sample, model, or release of a product built for the purpose of testing a concept or process. Generally, the prototype is used to evaluate a new product or concept design for its usefulness in the real world.

Additionally, the main motive behind a prototype is to validate the design early by collecting feedback from your target market that will guide your product development efforts.

Would you ever walk into a stakeholder meeting to present your concept without first getting customer feedback? Hopefully not. Doing so could undermine your credibility and your capacity to defend your design.

But communicating and justifying the value, look, and feel of your product to stakeholders before it’s been built can be a challenge. Prototyping makes it easier. 

Prototyping can help you:

• Better depict the intent of your final design
• Defend your design decisions with customer feedback
• Save you time and money by making needed changes early, rather than in final development
• Feel confident that what you present has a strong product-market fit

How to choose the right prototyping tool

With hundreds of different user testing tools out there today, it’s important to make sure the prototyping tools you choose will do what you need them to do. Here are four key things to consider.

• Purpose: What exactly does the tool do? Do the capabilities it offers match your specific testing needs? For examples, do you need a tool for building wireframes or something more general?
• User adoption: How easy will it be for your designers to adopt the tool? In other words, how easy will it be for them to go live on it and learn how to use it? How does the tool foster collaboration with other users, both inside and outside your company?
• Usage: How many people can use it at the same time? How will it help optimize your UX workflow?
• Price: What’s the pricing structure? What’s included at no additional cost with the tool, and what will cost extra? What are the thresholds at which the initial cost will increase?
