Adobe XD

Adobe XD is Adobe's UI/UX design and prototyping tool, built to fit naturally into workflows already using Photoshop and Illustrator. It supports vector-based screen design, auto-animate transitions for prototypes, and voice prototyping for testing voice-driven interfaces. XD integrates with Creative Cloud Libraries, allowing shared colors, character styles, and assets to flow between XD and other Adobe apps, which is useful for teams with an existing Adobe-centric design pipeline. While Adobe has shifted investment toward Figma-style collaborative tools industry-wide, XD remains actively used by teams already standardized on Creative Cloud.

ProtoPie

ProtoPie is an interactive prototyping platform used by product design teams at companies including Google, Meta, and Mercedes to build realistic, code-free prototypes. Rather than static click-through mockups, it lets designers wire up dynamic interactions using variables, formulas, and logic, and test them on real hardware such as phones, tablets, smartwatches, cars, and TVs. Beyond screen-based flows, ProtoPie supports native device sensor input, voice interactions, and connections to real data, which makes it popular for prototyping automotive HMI systems and IoT products in addition to standard app and web interfaces. Designs can be imported from tools like Figma and handed off as clean specs once a prototype is finalized.

UXPin

UXPin is a UX/UI design and prototyping tool that lets teams build interfaces using real, code-backed components instead of static shapes, bridging the gap between design and development. It includes built-in React component libraries like MUI, Tailwind UI, and Ant Design, an AI Component Creator, and Git and Storybook integrations for syncing custom design systems.

Justinmind

Justinmind is a design and prototyping platform used to build web and mobile app interfaces ranging from low-fidelity wireframes to high-fidelity interactive prototypes. It offers vector-based UI design tools, reusable design systems and UI kits, and interaction features like web animations, transitions, and mobile gestures such as tap, swipe, pinch, and scroll. The platform is used by teams at companies including Adobe, Google, and Cisco, and combines prototyping with requirements management, letting teams embed and track requirements directly inside prototypes. Finished work can be tested on iPhone, iPad, and Android through companion viewer and emulator apps, and exported as HTML, SVG, PNG, or developer specification documents.
