ProtoPie is a specialist for the moments when a clickable mockup is not enough. Designers import screens from Figma or Sketch and then add interaction logic, so prototypes can run across several devices at once. Through the Connect add-on, prototypes talk to Arduino boards and native hardware, which is why ProtoPie markets itself to automotive, aviation, medical and IoT teams. Handoff recordings and Dev View show developers exactly how an interaction should behave. The free plan holds 2 prototypes with 8 scenes each and 50 MB of cloud storage. Basic costs $25 per month for a single seat on yearly billing with 20 prototypes and no watermark, and Pro at $47 per editor per month adds unlimited prototypes, team libraries and 5GB of storage per team. ProtoPie does not replace a layout tool: you still draw screens elsewhere, so its cost sits on top of Figma, Sketch or Penpot.
