UA Switcher Pro - Multi-Level User-Agent Control

UA Switcher Pro is an advanced User-Agent (UA) switcher designed for developers, testers, and privacy-conscious users. It offers an unprecedented multi-level rule control system (Global, Domain-specific, and Tab-specific) and four flexible UA switching modes (Built-in, Custom, Append Text, and Random). Combined with a rich built-in UA library, powerful customization features, and zero-delay switching technology, it allows you to manage your browser's identity with ease and precision. Whether you need to debug mobile compatibility, bypass website restrictions, or enhance your online privacy, UA Switcher Pro provides the most reliable and flexible solution. ✨ Core Features 1. 🚦 Powerful Three-Tier Rule System Our unique "Tab > Domain > Global" priority rule system offers you ultimate flexibility and precise control: Global Rule: Set a default UA that applies to all websites you visit. Domain Rule: Assign a specific UA for a particular website (e.g., *.google.com or example.com), which overrides the global rule. Tab Rule: Set a temporary UA for the current tab only, which expires when the tab is closed. It's the perfect choice for quick tests or one-time visits and has the highest priority. 2. 🎭 Four Flexible UA Modes Freely choose the most suitable UA switching mode based on your needs: Built-in Mode: We have curated a library of over 200 real device UAs across 15 major categories, including the latest desktop browsers for Windows/macOS/Linux, mobile devices for iOS/Android, game consoles (PlayStation/Xbox/Switch), smart TVs, and even in-app browsers for specific applications like WeChat and TikTok. Custom Mode: Easily add, manage, and categorize your own UA strings to build a personalized library. Append Mode: Add a custom string to the end of your browser's original UA, ideal for traffic tagging or specific A/B testing scenarios. Random Mode: Automatically rotate UAs from a predefined pool (e.g., mobile devices only, or from your custom library) for each request or tab, significantly enhancing your anonymity. 3. ⚡️ Advanced Technology, Zero-Delay Switching Built on Manifest V3: Utilizes the latest Chrome extension standard for enhanced security and performance. Zero-Delay Rule Application: By leveraging the declarativeNetRequest API and an innovative "rule pre-registration" mechanism, we ensure the UA is modified before the network request is sent, fundamentally preventing any real UA leakage. Comprehensive Spoofing: Not only does it modify the User-Agent in HTTP headers, but it also spoofs JavaScript properties like navigator.userAgent and navigator.platform to bypass advanced detection methods. 4. 🛠️ Professional Configuration Management Import & Export: Easily back up all your rules and custom UA libraries, or share configurations with your team. Remote Configuration: Load configuration files from a URL for centralized team management and dynamic updates. Category Management: Organize your custom UAs and appended texts into categories to keep your library neat and tidy. 🎯 Why Should You Install UA Switcher Pro? 👨‍💻 For Web Developers and Testers: Efficient Debugging: Quickly simulate various desktop and mobile browsers to test responsive layouts and compatibility without switching devices. Precise Issue Reproduction: Use specific UAs to reproduce user-reported issues, dramatically improving debugging efficiency. Bypass Restrictions: Emulate search engine crawlers or specific clients to access APIs or content that requires a particular UA. 🕵️‍♂️ For Privacy-Conscious Users: Protect Your Digital Fingerprint: Reduce the uniqueness of your browser fingerprint by frequently and randomly changing your UA to prevent cross-site tracking. Access Restricted Content: Some websites limit content based on the User-Agent (e.g., mobile-only access). This extension allows you to bypass these restrictions easily. 📊 For Content Creators and Data Analysts: Simulate Different Devices: Understand how your content appears on various devices and platforms. Data Scraping: Mimic specific devices or crawlers to gather data more effectively and reliably. We are dedicated to creating a powerful, high-performance, and user-friendly User-Agent management tool.
