Adserver.Online review
Broad ad formats and programmatic workflows, with monthly plans tied to request volume.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Adserver.Online is a cloud-based ad serving platform for publishers, advertisers, ad networks, and agencies managing direct and programmatic campaigns across websites, apps, and video inventory. It combines ad delivery with targeting, conversion tracking, reporting, and white-label options. Its low entry price and broad format coverage make it relevant to small teams, while its workflows and APIs also address more involved ad operations.
The monthly plans scale by included ad requests: Promo Starter costs $29 and includes 1M requests; Core is $89 for 3M; Premium is $199 for 10M; and Ultimate is $599 for 50M, plus 15M empty programmatic requests and a 99.99% SLA. A 14-day trial is available, but there is no ongoing free plan. Buyers should compare expected monthly request volume with these tiers, especially if programmatic traffic is material.
Format and workflow breadth are central strengths. The platform serves image and HTML5 banners, third-party tags, native ads, popups, and video, with VAST, VMAP, VPAID, and SIMID support. OpenRTB, XML/JSON feeds, Prebid.js, and Prebid Server support programmatic workflows; targeting can use location, device attributes, carrier/ISP IP ranges, URLs, referrers, and user-agent substrings. REST and JavaScript APIs cover management, reporting, ad decisioning, dynamic loading, and callbacks, while white-label options include custom panel and ad-serving domains. Teams wanting broad capabilities on a budget may find a fit, but those seeking a free tier or support beyond documentation should look elsewhere.
