The short version

  • Only uBlock Origin has a free tier, so it costs nothing to try first.
  • Each has a real cost: TrustArc the software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.; 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
  • They diverge on capability: TrustArc covers Nymity Research, uBlock Origin covers Ad blocking.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

TrustArc

  • The software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • The integration catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.
  • Certification services are sold separately from the platform subscription, so the seal that is often the reason for choosing TrustArc is an extra line item and an extra annual renewal.
  • Reported contract values vary enormously by module mix and organisation size, and the absence of published pricing means smaller buyers have no anchor and routinely discover the entry price is higher than expected.
  • TrustArc stays inside privacy, so organisations that later want third-party risk, security compliance or ethics reporting on the same platform will be running a second vendor anyway.

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
