FAQ
User-Agent is a field in HTTP request headers that contains information about the client browser, operating system, device type, and more. Websites and servers use User-Agent to identify visitor device environments for adaptation or analytics.
It can identify browser name and version, OS name and version, device type (desktop/mobile/tablet), device vendor and model (Apple/Samsung/Google, etc.), and whether it is a bot/crawler.
Yes. The tool has built-in detection rules for common search engine crawlers (Googlebot, Bingbot, YandexBot, etc.), social media crawlers (Facebook, Twitter, etc.), and common crawling frameworks.
No. All parsing is done locally in the browser. Your User-Agent data is never uploaded to any server, protecting your privacy.
