Mobile View Switcher
The lightweight Chrome Extension for developers and privacy enthusiasts. Simulate devices, switch User-Agents, and browse without boundaries.
Why I built this tool
Mobile View Switcher is a professional-grade Chrome extension that empowers you to spoof your browser's
User-Agent string with a single click.
It enables you to masquerade as an iPhone, iPad, or Android device, forcing websites to serve their
mobile versions. Built on the modern declarativeNetRequest API, it operates without
injecting heavy scripts, ensuring your browsing remains fast, private, and secure. It's the essential
utility for developers, testers, and power users who need to break out of the desktop view.
