User-Agent Switcher by Semalt

User-Agent Switcher by Semalt lets you quickly and conveniently switch the User-Agent to view a site as if you were using another browser or device. A User-Agent is a string your browser sends to a site in the HTTP header and via navigator.userAgent. Servers and scripts can use it to identify the browser and device type and, if needed, deliver different content or apply different rules. With User-Agent Switcher by Semalt, you can easily switch—right inside Chrome and in just a few clicks—to built-in User-Agent profiles for various operating systems, browsers, search engines, devices, and more. ➋ Who can benefit from extension? ➣ Front-end engineers & QA — reproduce issues and test UA(User-Agent)-based redirects, polyfills, and responsive breakpoints without real devices. ➣ Technical SEO teams — check mobile/desktop parity, detect UA(User-Agent)-based cloaking, verify server rules that vary by User-Agent, quick spot-checks for Googlebot rendering (note: this doesn’t make requests from Google; it only changes the header). ➣ Product managers — validate rollouts or fallbacks for legacy browsers before launch. ➣ Customer support — quickly reproduce a user’s environment to triage bugs. ➣ Analytics/MarTech engineers — confirm tracking, tag firing, and AB test buckets that depend on User-Agent. ➣ AdOps/Monetization — verify ad tags and responsive placements under mobile/desktop User-Agents. ➣ Security/testing teams — assess allow/deny rules, WAF behavior, and rate-limit logic tied to User-Agent. ➣ Automation testers — run scripts that must declare a specific User-Agent for compatibility. ➌ How to install the extension?
