Klaro: sovereignty score and 8 European alternatives

Klaro is a consent manager for websites that helps with compliance with the GDPR and ePrivacy rules. It makes third-party services and tracking scripts on a site transparent and blocks them until the visitor gives consent; both implicit and explicit consent are supported. Klaro is lightweight, available in 23 languages and customisable. It can be used in three ways: loaded from the CDN, as a JavaScript file hosted on your own server, or via npm. KIProtect also offers a paid hosted service with server-side consent records, URL scans, a REST API and statistics.

The client library is open source under the BSD-3 licence. If you self-host Klaro, everything runs in the visitor's browser and no consent data is sent to a third party; the open-source version has no server-side functionality. KIProtect GmbH, the company behind Klaro, is based in Germany. The pages consulted do not state where the hosted service runs.

Why digital sovereignty matters with Klaro

Klaro is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Klaro hosts data outside the EU (Multiple). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Klaro 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 Klaro together with your other vendors and gives a total score, a heatmap and the main risk drivers.
