Prototyping is a crucial step in the UX design process. It entails creating a model of the product to validate your ideas. Prototypes can be low or high-fidelity but often when they’re used for testing with users, prototypes are clickable and you’re able to run specific scenarios with them before they’re taken live.
Like anything in UX, there are countless prototyping tools out there to help you get the job done. If you’re spoiled for choice and struggling to narrow it down, this guide is for you. We’ve compiled the 10 best UI UX prototyping tools for UX designers, complete with an explanation of how they work.
When you get to the end, you’ll also find some tips on how to choose the right prototyping tool for your needs.

Unlike some other prototyping tools on our list, ProtoPie focuses solely on prototyping, so you’ll need to import your static designs from another tool first. ProtoPie has plugins for Figma, Adobe XD and Sketch.
Once you’ve imported your wireframes, you turn them into interactive prototypes by adding triggers, responses, and objects. The trigger is the user action that will “cause” the interaction. The object is the element that the user will interact with in order to set the trigger in motion. The response is the result of the interaction—for example, opening a link or jumping to another page. You can build these interactions by simply selecting pre-made triggers and responses from the drop-down menu in the toolbar.
From there, you can use a range of additional features and tools to make your interactions more complex and precise. You can then preview your prototypes in the preview window, upload them to the cloud and share a link, or generate a QR code which you can scan in order to view the prototype using your smartphone.
ProtoPie is a powerful yet easy-to-use prototyping tool, a great combination for new UX designers. You can learn more about how to get started with ProtoPie in this tutorial.

How does UXPin work as a prototyping tool?
When prototyping with UXPin, you can either start from scratch or import existing designs from Sketch or Photoshop, as well as static PNG or JPG files.
Your prototypes are nested within projects, so you can navigate to the project view to see an overview of all your prototypes, as well as an activity feed on the right-hand side to see who’s working on what.
Once you’re working on a prototype, you’ll find that the UXPin interface is fairly similar to Sketch and Photoshop: a blank canvas in the middle and then various tools, shapes and icon libraries on the right and left-hand sides.
If you’re designing from scratch, you can use the pen tool and shapes to add the basic UI elements. From there, you can draw out clickable hotspot areas to add interactivity, insert ready-made elements and build out advanced interactions such as button hovers, expandable menus and conditional navigation flows. Or you can use AI elements to make fully functional prototypes in minutes. Drag and drop components that AI can render as code, or plug in code that renders as UI.
You’ll end up with fully clickable prototypes which, depending on their visual fidelity, can feel almost indistinguishable from a real, live product.

How to choose between prototyping tools
Some of the prototyping tools on our list are focused solely on prototyping, like Fluid UI and Proto.io. Others serve as end-to-end design tools, with all the features you need to go from static wireframes right through to developer handoff.
Some offer “free forever” plans ideal for solo designers, while others are more expensive and geared towards team collaboration.
Some tools offer AI components with their tools such as Visily or Uizard, while others haven’t gone the AI route yet, like Sketch.
Finally, we’ve also covered a mix of Mac-only tools, tools that are compatible with all operating systems, and some that work purely in the browser.
All this to say: Choosing the right prototyping tools depends on your specific needs with regards to:
- The number of people who will be using the prototyping tools
- The scale of your projects and the desired fidelity of your wireframes
- Whether or not you want to use AI in your prototypes
- Your budget
- The prototyping tools you already have in your UX toolkit
- The type of computer and operating system you’re using
Those factors alone should help you shortlist a few suitable tools! From there, sign up for free trials and experiment with different tools to see how you get on. It’s also worth checking if your preferred prototyping tools has good supporting resources, such as step-by-step guides and video tutorials you can follow along with.
