Marvel
Marvel is a cloud-based design and prototyping platform offering wireframing, mockups, and user testing. Drag-and-drop tools build interactive mobile and web prototypes with transitions. A “Handoff†feature provides developers with CSS code and design specs. Marvel also supports advanced user testing, capturing heatmaps and screen recordings. Real-time collaboration helps design teams gather feedback in one place. While a free plan is available for small personal projects, advanced capabilities (brand settings, unlimited projects) require paid subscriptions. Marvel’s intuitive interface suits both novice designers and experienced teams.
