A prototyping tool enables a designer to weave visuals, navigational elements, and interactions together to give a solid representation of how a design will behave and feel. It's an essential tool in any UI/UX designer's arsenal. If you haven't found the right tool to suit your needs just yet, here's a comprehensive list of some of the best prototyping tools used by top designers in the industry.

Prototypes are an opportunity to try things out and fine-tune the details. They’re an essential tool in communicating to stakeholders, and decision makers, how all of the elements of an idea will function together.

14 prototyping tools for UI/UX designers

Here are 14 prototyping tools to help you with your own design process:

1. Figma

Figma is an all-in-one tool that makes collaboration and accessibility easy for UX designers, developers, and anyone else on a team with a browser-based, cloud-hosted platform. If you’ve worked with Sketch before, you’ll find that Figma has a similar feel that makes it easy to get started with.

Consistency is a priority in web design, and you can use Figma’s flexible styles to control the appearance of text, grids, and other elements across a project. And a variety of useful plugins, like Autoflow for illustrating user flows, Figmotion for creating animations, and many others, enhance Figma’s functionality.

2. InVision Studio

Released in 2011, InVision has a well-established reputation, and their dedication to rolling out new functionality and adding to their design platform makes them a favorite among many designers.

With a host of well-designed tools, InVision gives designers the power to put together functional prototypes quickly and to share them with others. It offers so many nice features, including a handy vector drawing tool, repeatable components that can be changed sitewide, and tools for creating animations and other dynamic visual effects.

Collaboration and communication are also strengths of InVision. Freehand lets team members draw, add notes, and offer feedback. And through LiveShare, a prototype can be demonstrated with full interactivity. InVision makes it easy for team members to stay connected and work together throughout the course of a project.

3. Adobe XD

Adobe XD offers a vector-based system for putting together prototypes, including tools for creating interactions, transitions, and other types of dynamic functionality. Because it’s vector based, scaling and resizing elements is no problem.

Adobe XD work well alongside other Adobe family apps like Illustrator and Photoshop. It’s nice to be able to edit Adobe images, like a .psd, right in the application.

From UI design to UX design, Adobe XD covers all the tools a designer needs from conceptualization through high-resolution prototypes. And they’re continually adding to this product with monthly updates that expand its functionality.

6. Origami Studio

If you’re Facebook and your designers don’t have an app that they need, you build it for them. Origami Studio was created for Facebook designers out of necessity, and Facebook so graciously shared it with the rest of the design world.

For designers who need a more advanced system, Origami Studio offers powerful prototyping tools for websites and mobile apps. Central to Origami Studio is a patch editor that lets you build logic, behaviors, animations, and interactions. It comes with many prebuilt patches, and the site says you’ll most likely use just 15–20 of these for most of your prototyping work.

Origami Studio does have a bit of a learning curve that can be daunting at first. But the payoff of knowing how to use their prototyping tools and pulling off sophisticated prototypes makes it well worth learning. This power, along with its compatibility in working with Sketch, makes Origami Studio an important tool for designers who want to go above and beyond standard prototyping.

7. Justinmind

justinmind tool

Justinmind has been gathering momentum as a popular prototyping tool. There are quite a few reasons why, from drag-and-drop functionality, the capabilities to create the simplest to most sophisticated of apps and web prototypes, and plenty of support, like videos and blogs to help you learn how to use it. Justinmind isn’t as huge as some of the other prototyping tools out there, but they’re certainly an up-and-comer.

Justinmind comes with UI libraries and templates, as well as many other practical features.

Along with a well-designed user interface, Sketch offers a host of shortcuts at your fingertips to speed up the design process.

Many consider Sketch an industry standard when it comes to wireframes and prototyping, and its feature-packed and user-friendly interface are just a few reasons why so many designers choose it.
