  • They diverge on capability: Osano covers Consent banner, uBlock Origin covers Ad blocking.

Where each one falls short

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

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.

uBlock Origin

  • CNAME uncloaking of third-party trackers disguised as first-party is only available on Firefox, because the required DNS API does not exist in Chromium
  • HTML filtering of response bodies requires the webRequest.filterResponseData API, which is only available in Firefox
  • On Chromium-based browsers uBO is not reliably ready at browser launch, so tracker and advertisement payloads can reach already-open tabs before filtering starts
  • Pre-fetch blocking is not reliable on Chromium-based browsers because they give websites precedence over user settings
  • The Chromium build does not use the WebAssembly filtering code paths, because the extra manifest permission would create friction publishing to the Chrome Web Store
  • LZ4 storage compression is Firefox only, and on Chromium in incognito mode IndexedDB resets, so uBO launches with out-of-date filter lists
