RapidPrebidServer is a open-source software that allows publishers to conduct automated auctions using server-side (s2s, server-to-server) header bidding technology.
With RapidPrebidServer, publishers can give different DSPs access to their inventory and receive bids from multiple advertisers at once. In such an auction, all DSPs have equal access to bid.
RapidPrebidServer integrates with external DSPs using OpenRTB 2.6 and Dynamic Native Ads 1.2 protocols. Supported formats Display(Banner), Native, Video(VAST).
The ad spaces are served by the RapidPrebidServer on this Demo Page
