This random user agent generator online produces realistic browser and device UA strings for API testing, scraping, and compatibility checks. The User-Agent (UA) is a string sent by the browser or client in requests; servers often use it to identify device type, browser, and OS.
Open the page and click "Generate" or "Random" to get a random User-Agent. Click again to get different UAs for testing various client environments.
If the tool offers filters, you can limit to desktop or mobile, or to a specific browser (e.g. Chrome, Safari, Firefox), then generate a matching UA.
Copy the generated UA into your request headers (e.g. the User-Agent field) or test tool to simulate that client. Use only for legitimate testing and development in accordance with the target site’s terms.
Servers use the UA to identify client type and version and may return different content or APIs. Changing the UA during development helps simulate different devices or browsers and debug compatibility.
The tool generates strings based on real browser and device UA patterns, so they look plausible, but are not guaranteed to match a specific real device—suitable for testing and development only.
Using them for scraping or to bypass anti-bot measures may violate a site’s terms or the law. Use only on your own services or with permission, for compatibility testing and development.
