Overview

Product summary

Review the store description, core capabilities, and common use cases.

User Agent Switcher is simple, but powerful extension. And much easier to use the Internet, regardless of which browser or operating system you prefer.

It adds a toolbar button that you can use to toggle between different commonly used user agent strings.

So what’s a User Agent?

A user agent is a small text description of your device that is sent with every web request. Websites can detect the browser you’re using and serve different content - this is why iPhone and Android users see special mobile websites when they browse the web.

With this chrome extension, you can quickly and easily switch between user-agent strings. Also, you can set up specific URLs that you want to spoof every time.

Changing User-Agent allows you to mimic, spoof or fake other browsers, devices or search engine spiders.

AI product read

Browser user-agent string switcher/spoofer that modifies HTTP request headers and JavaScript navigator objects to emulate different browsers and devices.

Enables users to bypass browser/device detection by websites, allowing access to content that is restricted or differently served based on user-agent strings (e.g., accessing mobile-only pages from desktop, testing how sites render for different browsers).

User clicks the toolbar icon → popup displays grouped user-agent presets (Chrome, Firefox, IE, Safari, iOS, Android, Windows Phone) → user selects an agent → extension applies it via declarativeNetRequest session rules (HTTP header) and content script (JS object override) → badge shows current spoof state → user can also configure permanent per-domain spoofs and custom agents in the options page.

Target users: Web developers testing cross-browser compatibility / QA testers verifying site behavior across different user agents / Users who need to access browser-restricted or device-specific web content / SEO professionals checking search engine bot crawling behavior

Source code is heavily minified, making deep logic tracing difficult, but the overall architecture and absence of login/payment flows is clear
The 'error reporting' option (report_errors to spoofer-extension.appspot.com) is an optional telemetry feature, not a login or paid feature — it's unchecked by default

Monetization

No paid features detected

No paid features, premium tiers, subscription checks, or payment APIs exist. All keyword hits for 'pro' are false positives: in locale files 'pro' is a substring of Czech 'prohlížeč' (browser), in schema.json it's 'properties', and in minified JS it's part of variable names. The 'license' hit is jQuery's MIT license header. The only monetization signal is a cross-promotion banner for the developer's free 'Color Picker' extension in the popup footer — this is not a paid feature.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login or account required. The extension operates entirely locally using chrome.storage APIs (local, session, sync, managed). There is no authentication flow, no user account creation, no OAuth, and no remote login endpoint. The 'jwt' keyword hit is from _metadata/verified_contents.json (signed extension package metadata), and 'session' hits are chrome.storage.session calls for per-tab spoofing state — neither indicates authentication.
