ProtoPie

ProtoPie is a high-fidelity interaction prototyping software that falls under the category of UX/UI design and product prototyping tools. It is specifically designed for creating realistic, interactive prototypes without writing code, making it an essential solution for designers, product teams, and developers who need to validate complex user interactions before development. Launched by Studio XID Korea, ProtoPie enables designers to go beyond static mockups by simulating real-world behaviors and device functionalities. Unlike basic prototyping tools that only allow simple screen-to-screen transitions, ProtoPie supports advanced interaction logic, conditional flows, and sensor-based triggers. This means designers can prototype experiences that involve gestures, voice commands, accelerometer data, and even multi-device communication. For example, you can create a prototype where tilting a phone changes the interface or where a smartwatch interacts with a mobile app in real time. ProtoPie integrates seamlessly with popular design tools such as Figma, Sketch, Adobe XD, and Photoshop, allowing teams to import their UI designs and enhance them with dynamic interactions. Once the prototype is ready, it can be tested on actual devices using the ProtoPie Player, which supports previews via USB, QR codes, or IP connections. This real-device testing capability ensures that prototypes behave as they would in production environments, reducing the gap between design and development. One of ProtoPie’s standout features is its ability to handle cross-device and hardware integration. It is widely used in industries like automotive, IoT, and consumer electronics, where realistic interaction testing is critical. Automotive companies such as BMW and Ford use ProtoPie to prototype in-vehicle interfaces, while tech giants like Google and Meta leverage it for mobile and wearable experiences. This hardware-level fidelity makes ProtoPie a preferred choice for teams working on complex ecosystems. From a collaboration standpoint, ProtoPie offers cloud sharing, team libraries, and interaction recording, enabling smooth communication between designers, developers, and stakeholders. These features make it easier to conduct usability tests, gather feedback, and iterate quickly. Additionally, ProtoPie provides educational resources through ProtoPie School, helping users overcome the learning curve associated with advanced interaction design. In terms of business impact, ProtoPie has gained global traction, serving over 50,000 companies across 180+ countries. It has received multiple UX awards and consistently ranks as a top advanced prototyping tool in industry surveys. Backed by significant funding, ProtoPie continues to innovate by expanding sensor support, improving integrations, and enhancing real-time collaboration features. Uses of ProtoPie include: Designing and testing mobile app interactions with realistic gestures and animations. Prototyping automotive HMI systems for dashboards and infotainment. Creating IoT and wearable device experiences with sensor-based triggers. Conducting user testing and stakeholder demos with high-fidelity prototypes. Reducing engineering dependency by validating complex behaviors before development.
