What Is User-Agent and Why Change It?
User-Agent is a string that the browser sends to the web server with every request. It contains information about the browser, operating system, and device. Servers use User-Agent to determine content compatibility and also to detect bots.
When web scraping and automating, it's important to use realistic User-Agent strings. If your bot sends the same UA (or the standard "Python-requests/2.28"), websites will quickly detect and block it. UA rotation is one of the key methods for bypassing anti-bot systems.
How Does the Generator Work?
Our generator contains a database of current User-Agent strings for Chrome, Firefox, Safari, Edge, and mobile browsers. You can select browser type, platform (Desktop/Mobile), and quantity (1-50). Generation happens instantly in your browser.
Usage Tips
For scraping, we recommend using Chrome User-Agent strings of recent versions — they're the most common and cause the least suspicion. Combine UA rotation with quality proxies from GProxy for maximum effectiveness.
FAQ
How often should I change User-Agent? Ideally, with every new request or session. Use different UAs from the same browser family.
Can websites detect UA spoofing? Some anti-bot systems check UA consistency with the browser's JavaScript fingerprint. So during headless scraping, make sure the UA matches the actual browser.
