Inspect any site's ad tech stack — ad networks, header bidding, ad server slots, SDK data, and iframe hierarchies. For ad ops. Inspect any site's complete ad tech stack — ad networks, header bidding bids, ad server slots, SDK data, and iframe hierarchies — directly in your browser. AdStackLens is the fastest way for ad ops, publishers, and programmatic advertising professionals to debug live campaigns, audit competitor ad tech setups, and uncover ad serving chains without leaving the page. Hover over any ad to instantly see the network, size, and serving details. Open the detail panel to explore live bid responses with CPMs, slot targeting parameters, header bidding auction data, and nested cross-origin iframe hierarchies. DUAL DETECTION ENGINE FOR COMPLETE AD STACK VISIBILITY Two complementary detection layers work together to map the full ad tech stack: - CSS selector matching identifies ad containers across major ad networks and SSPs commonly used by publishers worldwide - SDK introspection reads runtime data directly from supported header bidding libraries and ad server tags to surface live bid data, slot configuration, and targeting parameters Combined, these layers give you the complete ad stack picture that no single detection method can provide — fast, organized, and right where you need it. WHAT YOU CAN INSPECT - Ad placements: identify and visualize every ad slot on the page - Ad server slots: slot paths, sizes, targeting key-values, out-of-page configurations - Header bidding: bid responses, CPMs, bidder names, ad server targeting, auction timeouts - SDK data: live data from supported ad tech SDKs including auction results and bidder parameters - Iframe hierarchies: nested ad serving chains across cross-origin frames - Custom CSS selectors: add your own detection rules for any ad network the built-in rules miss BUILT FOR AD TECH PROFESSIONALS PUBLISHERS & MEDIA OWNERS Audit your own ad tech setup, verify ad slots render correctly, and catch revenue leaks from header bidding misconfiguration before they cost you CPM. AD OPERATIONS Troubleshoot live campaigns by inspecting slot targeting, header bidding bids, and SDK parameters in seconds. No more guessing why a campaign is underdelivering. COMPETITIVE & MARKET ANALYSIS See which ad networks, SSPs, and header bidding partners power competitor sites. Useful for media planners, business development, and ad tech sales teams researching prospect accounts. SALES & PARTNERSHIPS Walk into prospect meetings with hard data on what ad tech the publisher already uses — instead of asking blind discovery questions.
