The management layer that sits above your header bidding demand partners and coordinates the auction. It handles timeouts, collects bids, passes the winner to the ad server, and provides unified reporting across all partners. Prebid is the dominant open-source option. Proprietary wrappers exist but introduce a dependency on the vendor who built them. Wrapper configuration, particularly timeout settings and partner prioritization, has a direct effect on yield. Most publishers set it once and don't revisit it often enough.
