Proto.io

Proto.io gives you the power to create high-fidelity prototypes that look and feel like the finished product. You can build complex interactions, transitions, and animations for mobile apps and web interfaces using a simple drag-and-drop editor. It eliminates the gap between static designs and functional reality, allowing you to test user flows and gather feedback before developers write any code.

You can start from scratch or import your existing assets directly from Figma, Adobe XD, or Sketch. The platform is designed for UX designers, product managers, and entrepreneurs who need to communicate their vision clearly to stakeholders. Whether you are building a simple landing page or a complex multi-screen mobile application, you can simulate touch gestures, keyboard inputs, and sensor events to ensure your user experience is flawless.
