The platform combines Nextcloud Files (storage and sync), Nextcloud Talk (chat and video), Nextcloud Groupware (calendar and contacts), and Nextcloud Office (real-time document editing) in a single installation. A REST API and 300+ marketplace apps extend it with LDAP, SAML, SharePoint, and hundreds of third-party integrations.

The platform is GDPR-native, supports HIPAA-capable configurations, and is used by major EU governments, universities, and public institutions that mandate on-premises data sovereignty.

Trusted by Siemens, the German Government, and thousands of public sector organisations across Europe, with 20,000+ GitHub stars and an active global community.

Why choose Nextcloud over Microsoft Office?

The decisive argument is data jurisdiction. Microsoft Office is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

Nextcloud removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.

Frequently asked questions

Is Nextcloud a good alternative to Microsoft Office?

Yes. Nextcloud is one of the top-ranked European alternatives to Microsoft Office in our directory, covering the same cloud & hosting use case. It is headquartered in Germany, where EU GDPR applies.

What's the main difference between Nextcloud and Microsoft Office?

The biggest difference is jurisdiction: Nextcloud is based in Germany, where EU GDPR applies, while Microsoft Office is headquartered in the United States and may transfer data outside Europe. For regulated industries or organisations following Schrems II guidance, this difference is decisive.

Is Nextcloud GDPR-compliant?

Nextcloud is based in Germany, where EU GDPR applies. EU customers should still verify the provider's hosting and subprocessors, but the service is designed for European data-protection requirements.

How do I migrate from Microsoft Office to Nextcloud?

Start by exporting your data from Microsoft Office (most providers offer an export in their settings). Then import into Nextcloud using its native import tool or migration guide. Running both in parallel for a week catches any feature or workflow gaps before you fully switch.
