Proto.io is a browser-based prototyping platform that lets designers and product teams build interactive, high-fidelity mockups without writing code. It supports mobile, tablet, and web app prototypes.
Users can create fully animated, touch-gesture-aware prototypes that closely mimic real app behavior. The platform includes a drag-and-drop editor, a library of pre-built UI components, and support for sharing prototypes with stakeholders for feedback. It integrates with tools like Sketch and works across teams through collaborative project features.
