Couchbase: sovereignty score and 8 European alternatives

Couchbase is a distributed NoSQL database platform, with Couchbase Server as its multi-service database and Couchbase Capella as its fully managed database-as-a-service. It is developed by Couchbase, Inc., headquartered in California and formed in 2011 through the merger of Membase and CouchOne. Couchbase Server can be deployed on premises or on any cloud, so organisations can run it in their own infrastructure or in a cloud of their choice.

Couchbase, Inc. is a US company. It was acquired by Haveli Investments in a transaction completed in September 2025. The vendor's public pages do not state the cloud regions used by Capella, so EU hosting cannot be confirmed; a self-deployed Couchbase Server in the organisation's own infrastructure keeps data under its control. No GDPR commitment or data processing agreement is published.

Why digital sovereignty matters with Couchbase

Couchbase 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.

Couchbase 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.

Couchbase is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Couchbase together with your other vendors and gives a total score, a heatmap and the main risk drivers.
