User-Agent Parser Online - Detect Browser, OS, Device from UA String

🧠 What is a User-Agent String?

A User-Agent is a string sent by your browser to the server that contains information about your device, operating system, browser type, and rendering engine. It's used for analytics, debugging, and content customization.

🔍 What This Tool Does

This free User-Agent Parser tool helps you decode and analyze any UA string to reveal:

  • Browser name and version (e.g. Chrome 114.0)
  • Operating system (e.g. Windows 10, macOS, Android)
  • Device type (Desktop, Mobile, Tablet)
  • Rendering engine if available (e.g. Blink, Gecko)

📘 Example

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36

Parsed as: Chrome 114.0 on Windows 10 (Desktop)
