+| `browser.mobile` | boolean | A boolean that is true if the browser is running on a mobile device [3] |  |
+| `browser.platform` | string | The platform on which the browser is running [4] | `Windows`; `macOS`; `Android` |

+The list of possible values is defined in the [W3C User-Agent Client Hints specification](https://wicg.github.io/ua-client-hints/#sec-ch-ua-platform). Note that some (but not all) of these values can overlap with values in the [`os.type` and `os.name` attributes](./os.md). However, for consistency, the values in the `browser.platform` attribute should capture the exact value that the user agent provides.
