Marvel Overview
Marvel is a web-based design and prototyping platform from Marvel App, Inc. that makes it quick and simple to turn ideas into interactive prototypes for apps and websites, usable on Windows and macOS through the browser. It is designed to be approachable for designers and non-designers alike: you can create screens within Marvel or upload designs and images, then add hotspots and transitions to link screens into a clickable prototype that behaves like a real app. Marvel includes simple design tools, a large set of UI elements, and user-testing and feedback features, and it can generate developer hand-off specifications, including measurements, colors, and downloadable assets, so teams can move from idea to build smoothly. Because it runs in the browser and emphasizes speed and ease, it is popular for rapid prototyping, design reviews, and collaboration. It is freemium, with a free tier and paid plans for teams.
