Chrome User Agent String Example

Paste any user-agent string — from a server log, a support ticket, or curiosity — and decode its browser, OS, engine and device type instantly, including known bots like Googlebot.

Paste a user-agent string above to see it decoded — browser, OS, engine, device type and known-bot detection, live as you type.

Result

This page prefills the parser with a real, current-format desktop Chrome user-agent string and decodes it on load, so you can see exactly what a typical Chrome-on-Windows request line looks like and how each of its parts maps to a browser name, version, operating system and rendering engine.

This is a worked example for the parser, not a report on your own browser — even if you happen to be reading this in Chrome right now, the box below shows the sample string, not your live navigator.userAgent. That distinction matters for anyone who needs to recognize a Chrome UA inside a log file or an incoming request rather than check what browser they personally are using; for your own current browser instead, use the separate What Is My Browser tool.

Once you have seen how the sample decodes, clear the box and paste in any other Chrome-family string — a different version, a Chromium-based browser claiming to be Chrome, or an unusual build — to see how the same parsing rules apply to it, including an honest 'Unknown' wherever a detail genuinely cannot be read from the string.

Accepted Formats & Rules

  • Live parsing as you type or paste, with no submit button: browser name and version, operating system, rendering engine and device type (desktop, mobile, tablet or bot) update on every keystroke.
  • Explicit known-bot detection with a plain yes/no flag plus the matched bot's name — Googlebot, Bingbot, facebookexternalhit, Twitterbot, AhrefsBot, SemrushBot and more.
  • A 'load my own current browser's UA' button fills the box with your real navigator.userAgent as a quick way to try the parser, though the core use case is pasting any arbitrary string.

Key Benefits

✓ Decode any user-agent string you paste in — copied from an access log, a support ticket or a webhook payload — not just your own browser's.
✓ Known crawlers and bots are called out explicitly by name, so you can tell a real visitor from Googlebot, Bingbot, AhrefsBot and dozens of others at a glance.
✓ Honest results: when a string cannot be confidently decoded, the tool says so plainly instead of guessing a browser or OS that is not really there.

Use Cases

  • • Paste a line copied straight out of a server access log to see instantly whether the visitor's UA is a normal desktop browser or a crawler pretending to be one.
  • • Check a suspicious hit in your analytics against the known-bot list to decide whether it is Googlebot, Bingbot, AhrefsBot or SemrushBot before writing a robots.txt rule around it.
  • • Verify a UA string a QA report or bug ticket mentions actually parses to the browser, OS and engine the reporter claims, instead of taking their word for it.
