OpenDataDiscovery: sovereignty score and 8 European alternatives

OpenDataDiscovery, known as the ODD Platform, is an open-source data governance platform that brings data discovery, data quality, a business glossary, lineage and data modelling into one environment. Data teams use it to catalogue datasets and check whether pipelines deliver what downstream users expect. The platform runs locally with Docker Compose or on Kubernetes with Helm charts, and the makers also offer a hosted SaaS version.

The platform is maintained by Provectus IT, Inc., based in San Francisco, California, United States, and is released under the Apache 2.0 licence. The source code is public on GitHub, so you can run it entirely on your own servers and keep the metadata within your own infrastructure. Because the vendor is US-based, a SaaS service is subject to US law, and the vendor's website does not state where that service is hosted. European organisations that want to keep catalogue metadata under their own control can use the self-hosted deployment and review the SaaS terms before choosing it.

Why digital sovereignty matters with OpenDataDiscovery

OpenDataDiscovery 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.

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

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