Proto.io

Web-based platform for high-fidelity, interactive app prototyping.

1. Overview

Proto.io is a browser-based tool for building high-fidelity prototypes of mobile, web, and desktop applications without writing code. It enables designers to create realistic, animated interactions using a visual interface and timeline editor. With built-in UI components, drag-and-drop editing, and user testing support, Proto.io is ideal for UX designers and product teams who need to simulate complex flows before development. Prototypes can be shared, commented on, and tested across devices.
