Proto.io  cover

About Proto.io

Proto.io is a web-based prototyping application. People build interactive web, iOS and Android prototypes by dragging and dropping elements, with no code involved, and can move from a basic wireframe to something that feels like a finished app.

What Proto.io offers

  • Drag-and-drop editor — the building blocks for a first prototype.
  • UI libraries — components that mimic their native counterparts.
  • Templates — customisable starting points for web and mobile.
  • Animation — micro-animations, state animations on a timeline and eighteen transition types.
  • Asset collection — static and animated icons, stock images and sound effects.

Who it works with

UX designers, entrepreneurs, product managers, marketers and anyone with an app idea.

Key facts

  • Delivery: runs entirely in the browser.
  • Skills: no coding needed.
