The short version

  • Only Osano has a free tier, so it costs nothing to try first.
  • Each has a real cost: Didomi pricing is based on monthly unique visitors and is not published, so a large publisher cannot estimate cost before entering a sales process, and traffic spikes translate directly into billing surprises.; 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.
  • They diverge on capability: Didomi covers Google CMP certification, Osano covers Consent banner.
  • Prices and features above were last checked on 31 August 2026.

  • A privacy counsel who wants a vendor that will contractually stand behind its consent product rather than disclaim all liabilitynot Didomi

Where each one falls short

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

Didomi

  • Pricing is based on monthly unique visitors and is not published, so a large publisher cannot estimate cost before entering a sales process, and traffic spikes translate directly into billing surprises.
  • Consent banners depress measurable traffic by design, and Didomi cannot prevent that, so publishers moving from a non-compliant banner should expect an immediate drop in tracked users and attributable conversions.
  • Certification is a moving target: Google and IAB update requirements periodically and each version change forces integration work on your side, not only on the vendor's.
  • Connected TV consent collection depends on the app platform and remote control interface, and implementations are considerably more involved than a web banner, often requiring per-platform development.
  • The wider privacy suite beyond consent is thinner than dedicated privacy platforms, so an organisation needing data subject rights automation and data mapping usually buys a second vendor anyway.

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.

Yes, it is a registered TCF CMP, currently supporting version 2.2 and later revisions.

Not published. Pricing is based on monthly unique visitors and quoted.

Osano: Can it handle US state privacy laws as well as GDPR?
