ClickHouse: sovereignty score and 8 European alternatives

ClickHouse is an open-source, column-oriented database for analytical (OLAP) workloads. Users run real-time analysis in standard SQL over large volumes of data, for example for analytics, observability, data warehousing and vector search. The software was originally developed at Yandex and is released under the Apache 2.0 licence. You can run ClickHouse yourself on your own machines or in the cloud, or use it as a managed service: ClickHouse Cloud, available on AWS, Google Cloud and Azure.

The company ClickHouse, Inc. is based in the San Francisco Bay Area, with a subsidiary, ClickHouse B.V., in Amsterdam. For the managed service, European regions are available, including Frankfurt, Ireland, London, the Netherlands and Germany (Azure), alongside regions in the United States. Because the code is open source, you can also host the database entirely yourself and keep data location and operations under your own control. With the managed service, the provider remains a US company.

Why digital sovereignty matters with ClickHouse

ClickHouse 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.

ClickHouse hosts data in US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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