String breakdown
| Fragment | Meaning |
|---|---|
Mozilla/5.0 | Historical compatibility token. Nearly every browser claims "Mozilla/5.0" so that old servers do not serve it broken pages. |
AppleWebKit/537.36 | WebKit rendering engine, build 537.36. Chromium browsers keep this token for compatibility. |
KHTML, like Gecko | Compatibility note: the engine descends from KHTML and behaves like Gecko. Kept for legacy browser sniffers. |
compatible | Compatibility token — historically sent by IE, now mostly by bots. |
Amazonbot/0.1 | Amazonbot 0.1 — an automated crawler/bot, not a real browser. |
Chrome/W.X.Y.Z | Chrome (or a Chromium-based browser), version W.X.Y.Z. |
Safari/537.36 | Safari/WebKit build 537.36 — a compatibility token, not the Safari version. Chromium browsers send it too. |
