Our verdict on OpenX

OpenX is a supply-side platform for publishers managing programmatic advertising across connected TV, display, video, mobile, digital out-of-home, and native formats. It combines inventory and deal management with header bidding, audience targeting, supply-side targeting, ad quality controls, and marketplace access. The platform is suited to small, mid-market, and enterprise publishers that need to connect inventory with advertiser demand while managing yield and buyer activity across multiple channels.

Pricing follows a contact-sales model, so publishers need to engage OpenX directly to discuss commercial terms. The product is delivered through the cloud and exposes web and API access. Its platform scope covers curated inventory, private marketplace deals, and first- and second-price auctions, giving teams options for both open-market monetization and more controlled trading arrangements. Real-time reporting and customizable reports cover yield, buyer activity, and the bid landscape, supporting ongoing revenue analysis.

OpenX’s breadth is its defining strength: publishers can manage varied formats, apply first- and third-party audience targeting, and filter, review, or block creatives from one supply-side environment. That range makes it a fit for organizations operating across several inventory channels or requiring detailed deal controls. Buyers seeking transparent self-serve subscription tiers, non-cloud deployment, or dedicated support channels should compare alternatives. Publishers comfortable with a sales-led purchasing process and community-based support will find a broad toolkit for inventory monetization and exchange operations.
