Your browser’s user agent is filled in: see which browser, engine, system and device it says you’re on. Paste any user agent from a log to read it.
User agents carry decades of history: nearly every one starts with Mozilla/5.0 and many mention Safari or Gecko even when they aren’t. This page looks for the parts that matter, in the right order (Edge before Chrome, Chrome before Safari).
| User agent (shortened) | Read as |
|---|---|
| … iPhone OS 17_4 … Version/17.4 … Safari/604.1 | Safari 17.4 on iOS 17.4, phone |
| … Windows NT 10.0 … Chrome/124 … Edg/124 | Edge 124 on Windows 10 or 11 |
| … compatible; Googlebot/2.1 … | Googlebot, a bot |
Less than before: browsers freeze parts of the string for privacy (Chrome reports Windows NT 10.0 for Windows 11). Use feature detection in code where you can.
