User-Agent Parser
Paste any User-Agent string to identify the browser, rendering engine, operating system, and device type, or detect common search engine and social media crawlers.
Parsed using common pattern matching for major browsers, operating systems, and search/social crawlers. Unusual or spoofed User-Agent strings, and less common browsers, may not be recognized correctly.
Frequently asked questions
Can User-Agent strings be faked?+
Yes, easily, any client can send any User-Agent string it wants, so this is useful for debugging and analytics, not for security decisions.
Why do so many User-Agent strings mention multiple browsers?+
For legacy compatibility. Chrome's UA includes "Safari" and Edge's UA includes both "Chrome" and "Safari" because many websites historically checked for those substrings before making decisions.
Does it detect search engine crawlers like Googlebot?+
Yes, common crawlers and bots (Googlebot, Bingbot, social media link-preview bots, popular SEO tools, and common HTTP client libraries) are recognized and labeled separately from real browsers.
