Overrides are persistent per page. You can set them standalone or during navigation.
# Set viewport and geolocation standalone
chrome-devtools --target main emulate --viewport 1920x1080 --geolocation 40.71,-74.00
# Emulate mobile device
chrome-devtools --target main emulate --viewport 375x812 --mobile --device-scale-factor 3
# Navigate with atomic emulation (sets environment before loading URL)
chrome-devtools navigate https://geotargetly.com --geolocation 51.50,-0.12
# Navigate as mobile device
chrome-devtools navigate https://example.com --viewport 375x812 --mobile
# Open new tab with atomic emulation
chrome-devtools new-page https://example.com --viewport 375x812
# Clear emulation overrides
chrome-devtools --target main emulate --clear-all
