The short version

  • Each has a real cost: Clio priced per user per month, so cost scales directly with headcount and adds up for growing firms; 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.
  • They diverge on capability: Clio covers Matter management, Didomi covers Google CMP certification.
  • 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.

Clio

  • Priced per user per month, so cost scales directly with headcount and adds up for growing firms
  • Advanced features including some automation and reporting sit in higher tiers rather than the entry plan
  • Aimed at small and mid-sized firms; large firms with complex matter structures often need heavier systems
  • Strongest in North America, with less depth in other jurisdictions’ compliance requirements

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.
