What is User Agent Parser?
A user agent parser analyzes the user agent string that every browser sends with HTTP requests.
It extracts structured information including the browser name and version, operating system and version, device type (desktop, mobile, tablet, or bot), and the rendering engine (Blink, WebKit, Gecko, or Trident). This tool auto-detects your current browser's user agent on page load and lets you paste any custom user agent string for analysis.
