MariaDB: sovereignty score and 8 European alternatives

MariaDB is a relational database created by the original developers of MySQL as a drop-in replacement for it. MariaDB Server is free and open-source software licensed under GPLv2. The company MariaDB also sells a product line: Community Server for development environments, Enterprise Server with support and long-term releases, the MaxScale database proxy, and MariaDB Cloud, a fully managed cloud service. According to the company, the platform handles transactional, analytical, semi-structured and AI data, with features such as vector search and MySQL and Oracle compatibility.

The MariaDB Foundation is a non-profit organisation incorporated in Delaware, US, which safeguards the continuity of MariaDB Server. The commercial company has been owned since September 2024 by K1 Investment Management of California, US, following a tender offer for all of its shares. That US ownership is the CLOUD-Act signal. Because the server is open source, you can run it yourself in a European data centre; the sources consulted do not state which regions MariaDB Cloud offers.

Why digital sovereignty matters with MariaDB

MariaDB is headquartered in FI and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

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

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