Features & Capabilities

Have you ever been blocked from a website for using the "wrong" device? Or needed to test how your responsive web design looks on a mobile screen? Smart UA Manager is the essential tool that gives you complete control over your browser's User-Agent on a per-website basis.

This lightweight and powerful extension allows you to set specific User-Agent (UA) rules for any domain you visit. The rules are saved and automatically applied every time, ensuring a seamless experience without needing to change settings on every visit.

Key Features:

Per-Site Management: Create and manage unique User-Agent rules for each website. Your settings for one site won't affect others.


One-Click Presets: Instantly switch to a standard Desktop (Windows Chrome) or Mobile (Android Chrome) User-Agent with a single click in the popup menu.
Fully Custom User-Agent: For advanced control, you can define and save your own custom UA string for any domain.
Active Domains Dashboard: Easily see a list of all websites with active UA rules and remove them at any time from the extension's popup.
Deep Spoofing: Smart UA Manager goes beyond just changing the HTTP header. It also modifies the navigator.userAgent property within the page's JavaScript, providing deeper and more reliable compatibility with modern websites that use client-side detection.

Simple & Efficient: A clean, intuitive interface makes managing your UAs effortless. The extension runs efficiently in the background without slowing down your browser.

Who is this for?

Web Developers & QA Testers: Quickly test mobile and desktop versions of your site without needing multiple devices.


Power Users: Access mobile-only deals, bypass "use our app" banners, or view sites that incorrectly block your browser.

Privacy-Conscious Individuals: Mask your browser's default fingerprint by providing a more common User-Agent.

Take control of your web browsing experience with Smart UA Manager!
