Marvel

Marvel is the quick prototyping layer you pull up when speed matters. It lets you wireframe, prototype and validate ideas in the browser so you can stop explaining concepts and start showing them. The workflow focuses on moving from sketch to clickable demo, then to testable prototype without extra setup. That straightforward flow is why teams use Marvel to iterate fast and keep stakeholders aligned.

Where Marvel pulls ahead is in integrated user testing and tidy developer handoff. The built in user testing tools let you recruit participants and capture session data without stitching together half a dozen apps, which speeds evidence-gathering for IA and flows. The automatic specs and export options make handoff less argument-prone, and integrations plug Marvel into the rest of your stack so collaboration does not stall at the prototype stage.

The prototyping logic can feel basic for complex conditional states and data driven interactions. For heavier interaction work you’ll probably want a code based prototype or a more advanced prototyping tool such as Framer or ProtoPie. Users also mention a learning curve for some features and occasional export quirks, so test your pipeline before you commit. Still, for fast mockups, legit user testing, and tidy handoff, Marvel is a practical, low friction option that gets work moving.
