Office EU: Europe's New Digital Sovereignty Play in the Productivity Suite Wars

The European Union is making a bold move in the digital sovereignty arena with the launch of Office EU, a new cloud-based productivity suite that aims to challenge the dominance of Microsoft 365 and Google Workspace while keeping European data firmly within European borders.

A Familiar Stack Under the European Flag

At first glance, Office EU presents itself as a complete cloud-based office suite that is "100 percent European-owned and runs entirely on European infrastructure." The company, registered as EUfforic Europe BV in November 2025 and based in The Hague, Netherlands, is positioning itself as the European answer to American tech giants.

However, a closer examination reveals that Office EU is essentially a hosted instance of Nextcloud Hub, the popular open-source collaboration platform. The website's description links directly to the Nextcloud homepage rather than a specific product page, and further investigation confirms that the suite is built on Nextcloud's foundation.

The Office Suite Under the Hood

The real story lies in what powers the document editing capabilities. Nextcloud has gone through several iterations of integrated office suites:

• 2020: Nextcloud 18.0.0 integrated OnlyOffice
• 2020: Nextcloud 19.0.0 switched to Collabora Online as the default
• 2025: Nextcloud added Thinkfree Office as an additional option

The current iteration of Office EU appears to be using Collabora Online, which is based on LibreOffice and developed by Collabora Productivity. This choice is significant because it represents a mature, open-source solution that can handle Microsoft Office document formats while maintaining complete European control over the codebase.

Why Digital Sovereignty Matters Now

The timing of Office EU's launch is particularly relevant. At the recent Open Source Policy Summit, digital sovereignty emerged as a much more immediate concern than in previous years. European organizations are increasingly wary of relying on US-based cloud services, especially given concerns about data privacy, surveillance, and the potential for sudden policy changes that could affect European businesses.

Office EU's hosting infrastructure appears to be based in a Hetzner datacenter in Helsinki, Finland. While Hetzner is a large German company with extensive European presence, this choice demonstrates a commitment to keeping European data within European borders.

The Self-Hosting Alternative

One of the most interesting aspects of this development is that organizations don't actually need to rely on Office EU to achieve similar results. Nextcloud Hub, with either Collabora Online or OnlyOffice, can be self-hosted on European infrastructure. This means that technically savvy organizations can achieve the same goals of data sovereignty without depending on a third-party provider.

However, the reality is that many organizations, particularly those looking to migrate away from US providers quickly, may lack the technical expertise or resources to set up and maintain such systems themselves. This is where services like Office EU become valuable – they provide a turnkey solution for organizations that want European sovereignty without the complexity of self-hosting.

The Register has reached out to both Office EU and Nextcloud for comment on this analysis, and will update this story if responses are received.

The Broader Context

This move fits into a larger pattern of European efforts to assert technological independence. From the Gaia-X initiative for federated data infrastructure to various national efforts at developing European cloud services, there's a clear push to reduce dependence on American and Chinese technology providers.

Office EU represents perhaps the most direct challenge yet to the American productivity suite duopoly in the European market. By combining the proven technology of Nextcloud with European hosting and ownership, it offers organizations a path to maintain productivity while ensuring their data remains under European jurisdiction.

The success of Office EU will likely depend on factors beyond just the technology – pricing, support, integration with existing European IT infrastructure, and the ability to convince organizations to switch from established platforms will all play crucial roles. But as digital sovereignty becomes an increasingly important consideration for European organizations, Office EU has positioned itself at the intersection of a growing need and a proven technological solution.
