Marvel is an approachable prototyping tool for non-designers and small teams: drag-and-drop wireframing, hotspots and transitions for clickable prototypes, plus automatic CSS/Swift/Android XML spec generation for developer handoff.
Free tier available. Pro $12/month. Team $42/month. Enterprise custom. Up to 25% off with annual billing.
Startups and non-designers who need to go from idea to a clickable prototype quickly, without learning a complex professional design tool first.
Automatic dev-spec generation (CSS, Swift, Android XML) from the prototype is a real time-saver for handoff, worth using even for simple prototypes if engineering needs implementation specs.
Turn sketches, mockups, and wireframes into interactive prototypes.
