CoreDNS: sovereignty score and 8 European alternatives

CoreDNS is a DNS server written in Go. It works as a chain of plugins, each performing one DNS function, for example serving zone files, rewriting queries, exposing Prometheus metrics, signing zones or resolving Kubernetes services. Administrators configure it in a Corefile and can compile a build that contains only the plugins they need. It integrates with Kubernetes for service discovery and with etcd, and has plugins for Azure DNS, Google Cloud DNS and Amazon Route 53. CoreDNS is software that you run yourself, on servers or in clusters; the project does not offer a hosted service.

CoreDNS is open source under the Apache License 2.0 and is a graduated project of the Cloud Native Computing Foundation, part of the Linux Foundation. Development takes place on GitHub. Because you operate it yourself, DNS data stays wherever you deploy it, including within the EU, and no vendor has access to your queries. This gives a European organisation control over hosting and updates, at the price of running and maintaining the service.

Why digital sovereignty matters with CoreDNS

CoreDNS is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Data is hosted exclusively in the EU, so CoreDNS scores best on data residency.

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