About ProtoPie

ProtoPie is the go-to tool when Figma's built-in prototyping isn't enough. It creates production-realistic interactions using sensors (accelerometer, gyroscope, sound), device features (camera, haptics), variables, conditional logic, and multi-device communication—all without writing code. Import designs from Figma, Sketch, or Adobe XD and add interactions that feel like the real app. ProtoPie Connect enables multi-screen prototypes and even hardware integration via Arduino. Used by Google, Microsoft, and Nintendo for testing complex interactions before development. Pricing: Free tier allows 1 active prototype; Basic ($13/month billed annually) removes limits; Pro ($25/month) adds team features; Enterprise includes ProtoPie Connect for hardware prototyping.
