Mockup tools help you take your idea to a digital prototype with ease. They help you “wireframe” a product design with a workflow to create a highly accurate prototype of what a finished product would look and function like.
Mockup tools are mostly used for creating app mockups, but they also help you create user interfaces, web designs, onboarding tools, and more.
Oftentimes, mockup tools can be quite expensive and very advanced, but if you’re looking for a free mockup tool that will help you get the job done quickly and easily, keep on reading!

Figma is one of the best free mockup tools because it comes with a very decent free plan that’s not a trial, and yet it is an all-in-one tool that can help you turn your designs into mockups and prototypes to develop apps or products faster.
This tool helps in three ways. The first and the most important step is brainstorming, where you get to use diagrams, sticky notes, or workshops and even collaborate with a team to get your ideas flowing.
The second step is the design phase, where you get to put all your ideas into the design with a real-time side-by-side view of what’s going on, as you also get to collaborate with your team in this step of the process.
The third step is the build process, where you get to build systems in place that will connect your ideas and your design and make a working mockup out of it so you can not only visualize your idea but also give it a try to see what else needs to be worked on.
Figma is also a pretty popular free mockup tool because it has a community full of freelancers and UI/UX designers who can share ideas, digital assets, and help each other with advice so you won’t ever feel stuck or uninspired.

Marvel is also popular for its user testing feature where you can see how users would interact with your mockup, from where you can gain feedback and collaborate further to improve your prototype.

What’s also unique about MockFlow is that it allows creators to create on-board tours for UI design mockups and even validate their designs with user testing capability. Therefore, you can easily turn your thoughts and ideas into an actual mockup that you can develop further with ease.
