Best Free Mockup Tools

If you’re a UI/UX designer who is looking for a simple, convenient, and most importantly, free way to create mockups, any of these 15 best free mockup tools can become very handy, so check out the list to find the one that will fit your needs the best!

1. Figma

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.

2. Marvel

Marvel is a free mockup tool that can help take ideas to life while providing designers and teams to collaborate on projects in real-time.

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.
