Need a tool that detects violations, not just hosts banners?
Every CMP on this list helps you display a banner. Only ConsentScope tells you if that banner is actually working. Catch cookies, scripts and storage leaks before your users do.
Frequently asked questions
Do I need a CMP and a cookie audit tool?
Ideally, yes. A CMP (like Cookiebot or OneTrust) displays the consent banner and manages user choices. A cookie audit tool (like ConsentScope) verifies that the CMP is actually blocking cookies and scripts before consent. They complement each other.
Which tool is best for small websites?
For small sites with basic needs, Cookiebot's free plan or Complianz (WordPress) are solid choices. If you need to audit multiple client sites or generate compliance reports, ConsentScope Pro is the most cost-effective at a one-time $19.99 payment.
Can I use ConsentScope with my existing CMP?
Absolutely. ConsentScope does not replace your CMP. It sits next to it as a monitoring and verification layer. It recognizes Cookiebot, OneTrust, Didomi, Usercentrics and 8+ other platforms automatically.
Is OneTrust worth the price for small teams?
For most small teams, OneTrust is overkill. You pay for enterprise features like vendor risk monitoring, policy management and DSAR workflows that you may never use. Consider starting with a simpler CMP and upgrading when your compliance needs grow.
