Complianz vs ConsentOS
Which cookie consent tool fits your site best?
The choice between Complianz and Consentos is essentially a choice between a commercial automation tool and a bare-bones open-source framework. Where one is aimed at end-users, the other is purely designed as a building kit for developers.
Where they are identical
Although their approach differs significantly, the end result is identical: both tools facilitate making your website GDPR-compliant. They provide a mechanism to request visitor consent, store it (locally), and act upon it by blocking external scripts. In doing so, the consent data never leaves your own server.
Where the difference lies
Convenience versus Control. Complianz (Dutch) is installed as a plugin in your WordPress environment. It scans your website automatically for cookies, includes a built-in generator for your privacy or cookie policy, and blocks the most common scripts fully automatically (via a wizard). Consentos does not provide this convenience. It is a self-hosted framework that you must install on your own server. It lacks an automatic scanner or policy generator; a developer must manually link all script logic.
Platform and Installation. Complianz is primarily focused on and built for the WordPress ecosystem. Consentos is platform-independent and integrates into any system via custom-made connections, provided you have the technical expertise in-house.
Costs. Consentos is free and open-source, but the implementation will cost you a significant amount of development hours. Complianz costs money (a fixed amount starting around $5/month), but saves those exact hours through extensive automation and the ready-to-use end product.

Our recommendation
For the vast majority of (WordPress) websites, we recommend Complianz. The time, effort, and technical frustration you save through the built-in policy generator and the automatic wizard easily outweigh the low monthly costs.
Choose Consentos exclusively if you are part of a technical development team that wants to be 100% independent of external software licenses, is willing to maintain the script logic internally, and does not use WordPress.
Setting up a banner does not equal compliance. Most violations occur post-installation because scripts still load too early via Google Tag Manager. Always run a free scan after configuration to verify it actually works.
