ProtoPie

ProtoPie is a no-code interactive prototyping tool that enables designers to build high-fidelity prototypes with realistic interactions, conditional logic, and sensor-based inputs—without writing a single line of code. Unlike simpler click-through prototyping tools, ProtoPie supports variables, formulas, conditional statements, and multi-device communication, making it one of the most powerful interaction prototyping platforms available.

Designers import their visual designs from Figma, Sketch, or Adobe XD and then layer complex interaction logic on top using ProtoPie's visual interaction editor. The tool supports interactions driven by device sensors such as gyroscope, accelerometer, sound input, and camera, which makes it particularly valuable for prototyping mobile, automotive, and IoT experiences.

ProtoPie Connect is a standout capability that bridges prototypes with external hardware, APIs, Arduino boards, IFTTT, and other connected devices. This allows teams to prototype multi-screen experiences where multiple devices communicate with each other in real time—a feature that sets ProtoPie apart from competitors like Figma's built-in prototyping, Principle, and Framer.

The platform is used by design teams at companies including Google, Microsoft, Samsung, BMW, Hyundai, and Nintendo. It has found particular traction in the automotive and IoT industries, where complex multi-screen and sensor-driven interfaces require prototyping fidelity that standard design tools cannot deliver.

ProtoPie runs on both macOS and Windows, and prototypes can be tested on real iOS and Android devices using the ProtoPie Player app. Teams can share prototypes via cloud links for stakeholder review, and the Enterprise plan supports on-premise deployment and single sign-on for organizations with strict security requirements.

As of early 2025, ProtoPie offers a free tier for individual use, paid Pro and Team plans for professional designers and collaborative teams, and custom Enterprise pricing for large organizations requiring advanced administration and deployment options.
