Is it possible to export and import custom devices from chrome developer tools?

I created my own custom devices on the Chrome developer tools and I would like to export them and import them in other computers ( or the same one in future installations ) without having to re create them one by one.

Is it possible to import/export some items or the whole list?

Solution

  • As wOxxOm has commented, the data is in the Preferences file.

    A more complete explanation for importing/exporting would be the following one:

    • On the source computer open a chrome tab and navigate to chrome://version/ this will give you some info. Get the Profile Path property, that's where the preferences file is saved.

    • Open the preferences file and look for the "customEmulatedDeviceList" property on this file and copy it, that's where all the custom devices have been stored.

    • Now open the same file on the target computer ( first close the Chrome browser or the new settings will be overriden by the current opened browser ) and paste the data you just copied. ( note: you need to create a custom device on this target computer or the "customEmulatedDeviceList" property won't exist ).

    The structure to be selected, copied and pasted is easier to locate if you first format the json file with any auto formatter.
