Firebird SQL: sovereignty score and 8 European alternatives

Firebird is a relational database with many ANSI SQL standard features, strong concurrency and support for stored procedures and triggers. According to the project, the software has been used in production systems since 1981 under various names. Firebird runs on Linux, Windows and several Unix platforms, and it is free to download, use and deploy, including in commercial products, with no registration or licence fees. The database is installed and operated by you; there is no vendor-hosted service.

The project is supported by the Firebird Foundation, a non-profit association under Czech law registered in Prague. The foundation raises money through dues, donations and sponsorship, grants funds for development and infrastructure, owns the Firebird trademark and protects the project's legal interests. Modifications to the source code must be released under the same IDPL licence. Because you host Firebird yourself, you decide where the data resides; there is no US parent company or cloud provider between you and your data.

Why digital sovereignty matters with Firebird SQL

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

Firebird SQL hosts data outside the EU (self-host). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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