What people use each for

The jobs each tool is most often brought in to do.

AdBlock Plus

  • Ad blocking for display ads, video advertisements including YouTube pre-roll/mid-roll/post-roll, pop-ups, flashing banners, and overlay adsnot Osano
  • Performance enhancement by eliminating ad content to accelerate page load times and reduce data and battery consumption on mobile devicesnot Osano

Osano

  • A mid market company selling into the EU and California that needs one banner honouring different consent rules by visitor regionnot AdBlock Plus
  • A privacy counsel who wants a vendor that will contractually stand behind its consent product rather than disclaim all liabilitynot AdBlock Plus
  • A marketing team that needs Google Consent Mode signals wired correctly so analytics and ads degrade rather than break when consent is refusednot AdBlock Plus
  • A company with a handful of brand domains wanting one consent record and one scanning schedule across all of themnot AdBlock Plus

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AdBlock Plus

  • Acceptable Ads allowlist model generates controversy over ad filtering conflicts of interest
  • Smaller feature set compared to open-source alternatives like uBlock Origin
  • Less customization and dynamic filtering compared to uBlock Origin
  • Mobile version less comprehensive than desktop extension
  • Chrome version increasingly limited due to Manifest V3 migration

Osano

  • The published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • The no fines guarantee is bounded and conditional on configuring the product as instructed, so it is a marketing differentiator with an indemnity cap rather than the insurance policy the name suggests, and the limits should be read before it influences a decision.
  • Everything beyond consent, including subject rights automation, data mapping and vendor monitoring, is enterprise quoted, so the transparent pricing that attracts buyers covers only the cheapest part of the platform.
  • Tag blocking depends on tags being loaded through the mechanisms Osano can intercept, and marketing teams that inject scripts directly into templates or through server side tagging routinely leak trackers past the banner without anyone noticing.
  • It is a privacy platform rather than a security compliance one, so organisations that also need SOC 2 or ISO 27001 evidence collection run it alongside a separate tool and duplicate parts of the vendor and asset inventory.
