Data & Infrastructure
90
Nextcloud sells self-hostable AGPL software; the vendor does not hold customer data, so residency follows the operator's own (often EU on-prem) infrastructure with no vendor-side CLOUD Act exposure. Score reflects that residency depends on the deployer, not the vendor.

What we don’t know
3 open questions — they lower confidence, never the score
- ?
Exact shareholder split of Nextcloud GmbH (founder vs. other holders) is behind registry paywalls.
Slightly lowers ownership confidence; the EU-control conclusion holds, but the precise founder stake is unconfirmed.
- ?
Current, vendor-confirmed employee headcount and revenue — public figures range from ~100 (vendor) to ~143 (trackers) and ~$7M revenue (third-party estimate).
Affects operations precision and scale pills, not the EU-centered conclusion.
- ?
For any given user, where data actually resides depends entirely on the operator's deployment choice, which the vendor does not control.
Infra score is for the vendor/architecture; a poorly chosen host could undercut real-world sovereignty despite the software.
EU Cloud Sovereignty Framework lens
The EU Cloud Sovereignty Framework targets cloud service providers; Nextcloud is self-hostable software, not a cloud, so this is an analogous mapping for orientation, not a certification.
Strategic
German founder-owned, self-funded, explicitly mission-driven on EU digital sovereignty; no foreign control or acquisition pressure.
Legal & jurisdictional
German GmbH fully subject to GDPR/BDSG and EU law; no foreign parent or extraterritorial owner.
Data & AI
Self-hosted, customer-controlled data; supports server-side and end-to-end encryption; vendor holds no user data by default.
Operational
EU-centered HQ and leadership; revenue base is European governments and enterprises; distributed but Europe-anchored team.
Supply chain
AGPL software stack reduces vendor lock-in, but real deployments depend on the host's infrastructure and any third-party SaaS partner chosen.
Technological
100% open source (AGPLv3), forkable and auditable; near-maximum anti-lock-in posture; open standards (LDAP/SAML/OAuth2).
Security & compliance
Bug bounty program, end-to-end encryption, used in high-assurance government settings; compliance ultimately depends on the operator's configuration.
Environmental sustainability
No vendor-operated data centers to assess; environmental footprint depends on the self-hosting operator.
EU alternatives
Already a near-maximum EU sovereignty option: German-owned, open source, self-hostable. The strongest peer in its category.
German government-backed sovereign workplace suite (which itself integrates Nextcloud); fully EU-controlled public-sector alternative.
French open-source, end-to-end encrypted collaboration; narrower feature scope and smaller backer than Nextcloud.
How the method works
Methodology v2 (provisional): the score is the midpoint of two axes — Control (who owns and governs the company) and Data (where your data lives and who can reach it). Each axis is scored only on verified evidence; unknowns reduce confidence, never the score. Every input below is sourced; the weights and judgments are open to challenge.
