ArcadeDB: sovereignty score and 8 European alternatives

ArcadeDB is an open-source multi-model database. It stores graphs, documents, key-value pairs, full-text search, vectors and time series in one engine, and it is licensed under Apache 2.0. The software is developed by Arcade Data Ltd, a private company. It is delivered for self-hosting: the project documents Docker, Kubernetes, binary installs and embedded use from Java. The vendor states that there are no cloud-only editions and offers paid Enterprise Support subscriptions. It can replace proprietary multi-model database licences.

Arcade Data Ltd is listed at a London address in the United Kingdom, which is outside the EU and the EEA, so the maintainer is not an EU company. The vendor pages do not state where data is stored or whether a GDPR or data processing agreement is offered. For a European organisation, the main sovereignty lever is the deployment: the Apache 2.0 code can run and be inspected on servers in the EU, without a foreign cloud provider in the loop.

Why digital sovereignty matters with ArcadeDB

ArcadeDB is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

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

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