Track browser information with the web trackers
The Snowplow web tracker supports tracking in all modern browsers, including newer browser features such as client hints.
Browser entity
Add an entity to every tracked event that records information about the user's browser. Configure it at tracker initialization.
The browser entity is automatically tracked once configured.
Availability
The browser entity is available since version 3.9 of the tracker.
Atomic event properties
The web trackers automatically capture browser and page information and add it to every event. You don't need to configure or manually include these properties.

These values are captured when the tracker initializes and remain constant for the session:

br_lang | Browser language |
dvce_screenwidth / dvce_screenheight | Screen resolution |

Set on every event
