Consent-O-Matic: sovereignty score and 8 European alternatives

Consent-O-Matic is a browser extension that answers cookie consent pop-ups on websites on the user's behalf, applying the choices made during setup. It is available for Chromium-based browsers, Firefox, Edge and Safari and targets individual visitors rather than website operators. The extension downloads and updates rule lists, and sends a report containing the site address only when a user flags a site that does not work. Preferences are stored locally in the browser.

The extension was developed by the Center for Advanced Visualization and Interaction (CAVI) at Aarhus University in Denmark, and its source code is published under the MIT licence. Because the software runs in the user's own browser and reports go to a service hosted by the university, a European user keeps control over the settings and over almost all of the data involved. Organisations looking for a consent management platform for their own websites need a different type of product.

Why digital sovereignty matters with Consent-O-Matic

Consent-O-Matic is headquartered in DK and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Consent-O-Matic scores best on data residency.

Consent-O-Matic is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Consent-O-Matic together with your other vendors and gives a total score, a heatmap and the main risk drivers.
