6 Best Prototype Testing Tools

Imagine this. You are building a brand-new website. Although you are aware of how you want it to function and look, you don’t know if users will like it or not.

It is crucial to validate your website before going live to avoid wasting extra money and time going through the development process and fixing mistakes over and over again.

And that’s where Prototype Testing saves the day.

A website or mobile application’s success is partially attributed to the UX design process. A significant portion of this process involves developing and testing prototypes prior to launch, and like everything in UX, there are a ton of tools available to assist you in completing these steps.

So, if you are struggling to find good prototype testing tools, we’ve compiled a list of the 6 best options on the market. Enjoy!

What is a prototype? 

A prototype is a product that has been developed as “an early sample, model or release of a product created to test a concept or process.” The prototype is typically used to assess a new product’s or concept design’s applicability in the actual world.

What is prototype testing?

Before sharing concepts with stakeholders and ultimately handing off the final designs to engineering teams for the development process, prototype testing involves putting your concept to the test. 

Prototype testing is the process of evaluating the usability of a prototype with real target users. It serves to uncover potential issues and pain points and as a way to identify areas of improvement at an early stage of development.

Why is prototype testing important?

Testing the usability of a developed product is certainly important as well, but imagine having to change the entire logic of your in-product flow because you find out after release that users are confused by it. It would be extremely time-consuming and costly to go back to the drawing board and design and develop the product from scratch again.

Development is expensive, and altering a finished product is more difficult than you would think. So it’s crucial to detect and correct problems as they arise during the design process! That is where testing a prototype saves the day and allows you to create a product that satisfies consumers’ requirements and expectations.

Still deciding whether to prototype or not? Take a look at this post about why prototyping is good for your website in further detail.

How does prototype testing work?

Before building your prototype and beginning testing, you should have a distinct understanding of what you want to test. This will assist you in determining the sort of prototype you require.

The complexity of prototypes can range from simple sketches to fully interactive and functional ones. High-fidelity prototypes are excellent for evaluating usability and finding problems in the process, whilst low-fidelity prototypes are mostly used to test out concepts.

When the prototype is complete, it’s time to show it to your target audience. Try to choose participants who are a good representation of your intended audience. You can find out what works and what needs to be changed by seeing how users engage with your prototype and hearing their comments. You can iterate and develop a better product using the information you’ve obtained.

Although testing prototypes may sound difficult, using the appropriate tools enables you to avoid some severe usability issues.

Here are the 6 Best Prototype Testing Tools:

  1. UXtweak
  2. Maze
  3. UserTesting
  4. UsabilityHub

Maze is a cloud-based software intended to support businesses in testing product prototypes, advertising campaigns, customer input, and design concepts.

prototype testing tools

You may import an existing prototype from your preferred design tool into Maze thanks to its direct integration with Adobe XD, Figma, InVision, Marvel, or Sketch.

Maze has a short learning curve, according to many users, and is enjoyable to use. They even have a community where you can go if you need assistance.

However, Maze doesn’t give a lot of demographic options from which to select a user base, which might be seen as a drawback.


Maze offers a Free Plan for 1 active project. 

If one active project is not enough for you, Maze also has a Professional Plan for $75/month, billed annually. 


For designers, product managers, marketers, and executives, UserTesting provides a range of customer experience (CX) solutions.

prototype testing tools

UserTesting was one of the first unmoderated testing sites ever. Its statistics show that it has more than 1.5 million panellists.

UserTesting supports a broad range of prototyping tools:

  • Adobe XD Plugin
  • Axure
  • Figma
  • Flinto (Lite/ Mac)
  • Framer
  • InVision
  • Justinmind
  • Marvel
  • Proto.io
  • ProtoPie

Your prototype may be shared with contributors through a prototype test or by referring to the content via a URL link and can range from a static image to a partially working prototype of an app or website.

The largest and most obvious drawback of the site is the abundance of pointless answers. Although UserTesting has a sizable volunteer base, it seems that a sizable portion of them are unqualified to take part in worthwhile research.

The fact that you cannot bring your own testers for free is another downside.


UserTesting has three plans, but the price is upon request. 


You may conduct many sorts of research tests and spot usability problems using the remote user research platform known as UsabilityHub. UsabilityHub helps you in validating any design choice for animations, logos, packaging, or video.

With UsabilityHub you can also test Figma prototypes.

They have an on-demand panel of over 170,000 testers embedded into their system. As an alternative, you may ask your own users to take part in the experiment.

Particularly for a single user, UsabilityHub is praised for how simple and easy it is to use. They have metrics for work time, open text analysis, click visualizations, and other reporting tools.

Textual responses to your research questions are UsabilityHub’s biggest drawback since they make it impossible to understand the genuine sentiments of your participants.


The free version is just intended for testing and lasts no more than two minutes.

Their Basic plan is $79/month and allows you to test for up to 5 minutes.

The Pro plan costs $199/month and includes multi-user plans, unlimited testing, and bespoke branding.


Userlytics is a long-standing international cloud-based usability testing tool that aids small and large enterprises in assessing a variety of digital assets, including websites, apps, prototypes, rivals, and more. By identifying the target demographic, the technology helps users to optimize the whole customer experience.

All prototype systems, including Proto.io, Invision, Figma, Marvel, Axure, JustInMind, UxPin, and others, are compatible with the Userlytics platform.

The absence of PDF reports as a feature of Userlytics is one of the biggest drawbacks.


The Quick & Easy program’s entry-level price is 49€/participant, while the Enterprise option is 69€/participant.

Additionally, they have the choice of providing customized pricing.


For designers and product managers who are interested in seeing how users engage with their apps, Lookback is a user experience (UX) screen recording tool.
