Master User Agent management and discover the best proxy software tools for maintaining online anonymity, optimizing web scraping operations, and managing multiple accounts with professional-grade solutions.
What is a User Agent and Why Does It Matter?
A User Agent is a string of text that your browser sends to websites, identifying what type of device, operating system, and browser you're using. This seemingly simple piece of information plays a crucial role in how websites serve content, track users, and implement security measures.
Example User Agent String
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36This tells the website you're using Chrome 120 on Windows 10 with a 64-bit architecture.
