‘Euro-Office’ Launches as Europe’s Sovereign Alternative to Microsoft Office

Casablanca – A coalition of European tech companies led by IONOS and Nextcloud has launched Euro-Office, a new open-source productivity suite aimed at giving public institutions, schools, and businesses a sovereign alternative to Microsoft Office, as demand for European-controlled digital tools continues to rise.

The tech preview went live last Friday following a Berlin press event, with the first stable release expected this summer.

The software is designed for documents, spreadsheets, and presentations, with developers promising strong compatibility with Microsoft file formats and an interface familiar enough to limit retraining during migration.

The project brings together more than a dozen organizations from across Europe, including Eurostack, XWiki, OpenProject, Soverin, Abilian, and BTactic, in what backers describe as a community-governed effort built fully under open-source licensing.

The push comes as European institutions increasingly rethink their reliance on US productivity and cloud platforms, especially after a year marked by geopolitical tensions and renewed concerns over digital dependence.

IONOS CEO Achim Weiss said those developments created a clear need for a “fully Microsoft-compatible and easy-to-use sovereign office solution” under European stewardship.

Nextcloud CEO Frank Karlitschek said the building blocks had existed for years, but Europe lacked a coordinated effort to turn them into a complete product.

That broader shift has already been visible in the market. Just days before the Euro-Office announcement, Nextcloud said sovereign workspace adoption had accelerated sharply, adding more than two million professional seats in 2025 alone.

The company said leads tripled last year compared with 2024, with especially strong demand from Germany, France, the Netherlands, Denmark, and even Brazil, suggesting the move toward sovereign software is no longer only a European conversation.

Several major public-sector deployments helped fuel that growth, including France’s Ministry of National Education, which currently has 400,000 employees using Nextcloud and aims to reach 1.2 million, as well as SURF in the Netherlands with 100,000 users.

Bookings rose by more than 50% year over year, giving added momentum to the launch of Euro-Office as Europe’s latest attempt to build a resilient digital infrastructure it can fully control.
