What does the User Agent Viewer do?

The user agent (UA) string is sent by your browser to every website and describes the browser, version, operating system and device type. Support teams often ask for it when troubleshooting. The viewer parses it into readable fields and, in browsers that support User-Agent Client Hints (Chrome, Edge and others), shows more precise details like platform version and architecture.

User agents are increasingly “frozen” for privacy — for example Windows 11 still reports “Windows NT 10.0” — so parsing is a best estimate.

How to use the User Agent Viewer

  1. Your user agent is filled in automatically.
  2. Read the parsed browser, OS and device details.
  3. Paste a different user agent (for example from server logs) to parse it.
  4. Copy the string for a support ticket.

Examples

Server log

Paste a UA from your logs to see whether a visit came from a phone, a desktop or a bot.

What is a client hint?

A newer, more privacy-aware way for browsers to share device details on request.
