Office EU, a 100% European owned alternative to Microsoft Office and Google Workspace, has officially launched in The Hague. The announcement marks another attempt to capitalise on Europe's growing frustration with cloud dependency. Yet beneath the sovereignty rhetoric lies a more complicated picture: the new service is built on established open-source foundations, raising questions about what genuine independence actually means in a globalised technology market.
The software is partly built on Nextcloud, the leading European open source platform. Further investigation suggests it likely uses Collabora Online, a LibreOffice-based document editor. This is not inherently problematic. Nextcloud and Collabora Online are proven, capable tools deployed across European governments and enterprises. The ability to assemble a reliable service from open-source components is itself a genuine strength.
What matters more is the honest conversation about what sovereignty actually delivers. The software is designed to fully comply with European laws and regulations and is therefore safe from legislative non-European control. The company was founded in 2024 and started operating early 2026. Data residency in European centres certainly helps. Yet legal scholars and security analysts note a persistent complication: even services hosted entirely in Europe may fall within reach of US legal demands under the CLOUD Act if their parent companies have any US connections.
The market context is real. Around 45% of organizations surveyed in Europe said interest in implementing digital sovereignty solutions has grown because of a host of recent geopolitical uncertainties from trade tensions to regional conflicts and regulatory shifts. Organizations legitimately want alternatives. The question is whether new entrants can deliver what marketing promises suggest.
Organizations looking to get their data and tools away from providers in the US and bring it inside the EU, in a hurry, may well lack the people and skills to do this. The more companies ready to help and make this easier, the better. This principle holds. Office EU's entry is welcome precisely because it reduces switching costs and removes barriers. Even if it is built on existing technology, assembling components into a managed service solves a real operational problem.
A measured perspective acknowledges both the genuine appeal and the practical limits. Europe should welcome competition in productivity software. Digital sovereignty is a legitimate concern that deserves serious solutions. At the same time, claiming total independence from US jurisdiction remains legally uncertain, even for European-hosted services. The honest answer is that Office EU and similar platforms offer real improvements in data control, privacy compliance, and operational autonomy, whilst remaining subject to the same international legal frameworks that constrain all technology providers operating globally. That is not failure; it is the current reality of digital infrastructure. Building better European alternatives remains worthwhile, provided we measure them by what they actually achieve rather than what marketing materials claim.
