Abstract: Systems and methods for providing a debugging interface for inserted elements in a resource are provided. One method includes detecting a trigger for a request to provide a debugging interface for a webpage, the webpage including a content interface configured to display third party content items. The method further includes transmitting the request for the debugging interface to a remote device, and receiving a script representing the debugging interface from the remote device. The method further includes inserting the debugging interface into the webpage by injecting the script into data of the webpage during loading of the webpage. The method further includes detecting a characteristic of at least one of the webpage, the content interface, or the remote device; and generating debugging information using the detected characteristic. The method further includes providing the debugging information in the debugging interface.
