Device Type

Learn how to set Oxylabs Agent Browser device types for more accurate scraping of responsive layouts and device-specific content.

Instead of manually setting viewports, touch support, and User-Agent headers in your local library config (which can create fingerprint mismatches and trigger connection timeouts), the Agent Browser allows you to emulate specific device classes natively by adding the p_device query parameter to your connection string:

wss://username:[e-mail]?p_device=mobile

Supported device profiles

You can configure the p_device parameter using three supported device profiles:

Parameter value	Description
desktop (default)	Full-size viewport, desktop platform headers, standard mouse/keyboard input schemas, and a desktop User-Agent string.
mobile	Compact mobile viewport, touch event APIs enabled, mobile OS platform headers, and a mobile User-Agent.
