About this tool
A random User-Agent generator creates browser identification strings that websites read to detect what browser, operating system, and device a visitor uses. FirstRandom's User-Agent tool builds realistic strings drawn from real-world browser signatures, ready to drop into your tests and scripts.
How It Works
Each generated User-Agent looks like a string a real browser would send - the right format, the right structure, and a believable mix of browser, version, and platform details. Set the count to generate as many random User-Agent strings as you need in a single click, then grab the results with copy or download.
Who Uses Random User-Agents
Web scrapers and crawlers rotate User-Agent strings to avoid being blocked or rate-limited by target sites. QA engineers feed varied User-Agents into automated tests to verify how a site responds across different browsers and devices. Backend developers use them to populate logs and test analytics pipelines with realistic traffic data. Security researchers rely on random User-Agents during web audits and penetration testing.
