Nextcloud Office: sovereignty score and 8 European alternatives

Nextcloud Office is the document-editing layer of the Nextcloud collaboration platform. Users write documents, work on spreadsheets and presentations and edit PDFs in the browser, with real-time co-editing, comments, tracked changes and a form builder. Supported formats include DOCX, XLSX, PPTX and ODF. The editing engine can be Collabora Online, which builds on LibreOffice technology, or Euro-Office, which is based on the ONLYOFFICE codebase; according to Nextcloud, from Hub 26 Spring either can be chosen with one click. Files are edited without leaving the Nextcloud server, which an organisation hosts itself or obtains from a provider.

Nextcloud GmbH is a German company with offices in Berlin and Stuttgart. It states that everything it does is 100% open source, without open-core or proprietary extensions; Nextcloud itself is licensed under the AGPL-3.0. Because the server runs where you choose, on your own infrastructure or with a European provider, the operator decides where data is stored and who controls the keys.

Why digital sovereignty matters with Nextcloud Office

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

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

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