Overview

U-Eyes is a Chrome extension for simulating mobile views on websites. Its core job is to help people preview responsive layouts, inspect how pages behave on different devices, and capture that view as screenshots or recordings.

The product pages position it as a tool for responsive testing, mock-up work, and website previews. The pricing page says it supports 35+ mobile devices, while the mockup page provides free high-quality device mockups for popular phones and tablets in downloadable PNG format.
