Interactive prototyping tool for creating high-fidelity prototypes with advanced interactions and animations.
Interactive prototyping tool for creating high-fidelity prototypes with advanced interactions and animations.
ProtoPie is a freemium no-code interactive prototyping tool in the design and interaction design category, with paid plans starting at $13/month for individuals and $41/user/month for teams, purpose-built for creating high-fidelity prototypes with realistic interactions, conditional logic, and sensor-based inputs without writing code.
Unlike simpler prototyping features built into visual design tools, ProtoPie supports variables, formulas, conditional statements, and multi-device communication through its proprietary ProtoPie Connect technology. This makes it one of the most capable no-code prototyping platforms available, particularly for complex interaction design in automotive, IoT, and multi-screen product environments.
ProtoPie is used by over 100,000 designers across design teams at major enterprises including Google, Microsoft, Samsung, BMW, Hyundai, and Nintendo. According to ProtoPie, the platform is used by teams at 9 of the top 10 global automakers for HMI prototyping, and it has been adopted by over 50 Fortune 500 companies for product design workflows. The platform supports importing designs directly from Figma, Sketch, and Adobe XD, allowing designers to keep their existing visual design workflow while adding a sophisticated interaction layer on top. ProtoPie Studio runs natively on both macOS and Windows, while the ProtoPie Player app is available on iOS and Android for on-device testing with full sensor support.
Key capabilities that set ProtoPie apart include native device sensor support (gyroscope, accelerometer, compass, sound input, and camera), voice interaction prototyping, and the ability to prototype complete multi-device ecosystems where screens communicate in real time. ProtoPie Connect extends prototyping to hardware integration with Arduino boards, APIs, and IFTTT-connected devices, making it the tool of choice for automotive HMI and IoT interface design.
The platform offers a free tier for individual learners and basic prototyping, with paid plans scaling from individual designer use to enterprise deployments with SSO, admin dashboards, and on-premise hosting options. ProtoPie also provides ProtoPie School, a structured learning resource with over 200 tutorials, to help designers master the interaction logic engine. In 2025, ProtoPie introduced ProtoPie AI in beta, adding AI-assisted prototype generation capabilities to the platform. With integrations with the most popular design tools in the industry, ProtoPie fills a critical gap between static design mockups and fully coded prototypes.

ProtoPie's interaction engine supports variables, formulas, and conditional statements that enable truly dynamic prototypes. Designers can create interactions like real-time form validation, calculated fields, and state-dependent UI changes—all without writing code. This logic layer is what elevates ProtoPie beyond simple animation tools into a full interaction prototyping platform.
ProtoPie Connect bridges the gap between screen prototypes and the physical world by enabling real-time communication between multiple devices, Arduino boards, APIs, and IFTTT. Teams can prototype complete ecosystems—such as a car's instrument cluster, infotainment screen, and mobile companion app all interacting simultaneously. This capability is unique among no-code prototyping tools and is the primary reason enterprises in automotive and IoT choose ProtoPie over alternatives.
Prototypes can respond to real device sensors including gyroscope, accelerometer, compass, sound input, and camera. This means designers can prototype tilt-to-scroll interfaces, shake-to-undo gestures, or sound-reactive animations that behave identically to production apps. Testing on real devices via ProtoPie Player makes sensor-driven prototypes feel indistinguishable from finished products.
Launched in 2025, ProtoPie AI introduces artificial intelligence capabilities to assist with prototype creation and interaction design. The AI feature aims to reduce the time spent building complex interaction logic by helping designers generate and refine prototypes more efficiently. As a beta feature still under active development, its capabilities are evolving—designers should check the ProtoPie website for the latest information on supported AI workflows and availability.
ProtoPie supports voice command recognition and speech-based interactions natively within prototypes. Designers can build and test voice-controlled interfaces, conversational UI patterns, and multimodal experiences that combine voice with touch and gesture inputs. This is particularly valuable for automotive, smart speaker, and accessibility-focused product teams designing hands-free experiences.
