Updated: May 16, 2022, the organization that oversees open source Prebid programmatic advertising solutions, announced the release of Professor Prebid. It is an open-source Chrome browser extension that allows for easy debugging and troubleshooting on publisher websites using Prebid.js to streamline header bidding management.

Professor Prebid provides an intuitive interface that detects when a web page has Prebid.js installed and offers an array of features to help publishers, including the ability to:

  • Check all ad units available to Prebid along with what banner sizes it supports and what bidders are participating
  • Deep-dive into the bids, including bid value, bid currency, response time, and ad server targeting keywords
  • View a detailed timeline of the auction’s main milestones
  • Confirm the main Prebid modules and their configurations (Price Granularity, Bidder settings, Prebid Server, CMP, User ID Modules)
  • View the user IDs available from the different ID providers on the page
  • Access to tools that enable Prebid Debug data on console view, which allows setting up manual bid filtering and the creation of CPM overrides to test various bidding scenarios easily.
