    Proto.io is the perfect solution for UX/UI designers that need to create and share interactive prototypes. Proto excels at the interactive part. There are so many different ways to make elements change or interact, whether you're viewing the prototype on a computer (mouse clicks) or on a phone (screen touches). We could build and prototype our entire mobile app on here if we wanted to because Proto.io has the customization that we need to make the app look and feel like ours. If you're looking for a software to create wireframes and static mockups, Proto.io is probably overkill for you.

    Supernova.io
    Supernova is the best documentation platform on the market, having tested numerous alternatives, including the more popular zeroheight, Knapsack, etc. It's ideal for low-code solutions for brand guidelines and detailed component documentation. Their automated exporter pipelines are the icing on the cake, enabling them to pull what you see in Figma and push it directly into your codebase.

    It is occasionally buggy, but nowhere near as buggy as zeroheight.

    Proto.io is definitely the premier mockup and wireframe application. Lucidchart shares some of the capability but can be a bit clunky. Proto.io is interactive and smooth and helps you to see exactly how your UI will look and behave before the development stage. Additionally, it's library of native components is robust.

    Supernova.io
    Supernova has best-in-class customer service. Our Figma library is a huge file and was unable to automatically sync with most platforms (including Supernova) - of all three platforms we tried, Supernova was the only one that actively assigned engineers to our case and offered a solution within a couple of days. They've been great partners.
