The project favors a modern architecture and may continue collaboration with Collabora, potentially integrating Collabora components into Euro-Office.

A European alliance led by Ionos and Nextcloud unveiled Euro-Office, a sovereign, Microsoft-compatible office suite designed to rival Microsoft Office, with a public tech preview now available and a first stable release planned for the summer.

Leaders stress that Euro-Office represents trusted, durable, Europe-managed digital infrastructure, with Nextcloud CEO Frank Karlitschek underscoring responsibility for a vital system.

Officials frame the project as appealing to public sector buyers and regulated industries by offering governance, licensing terms, and long-term maintenance under European stewardship.

Backers argue that current alternatives compromise compatibility, usability, or governance, highlighting legal and licensing concerns for public bodies handling sensitive data.

Development follows a shared governance framework including commercial open-source firms, independent developers, and civil society groups, with participants such as IONOS, Nextcloud, EuroStack, XWiki, OpenProject, Soverin, Abilian, OpenXchange and bTactic.

European policymakers and industry leaders say Europe has the talent and resources to manage its digital infrastructure domestically, presenting Euro-Office as a practical step toward greater autonomy and control over IT spending.

The motivation is to reduce dependence on non-European productivity platforms by offering a fully open-source, transparent, European-governed alternative.

Open-source licensing enables other providers to operate Euro-Office components, including potential use by OpenDesk, and supports adoption by public sector and other stakeholders.

A broad European consortium backs the initiative, including EuroStack, XWiki, OpenProject, Soverin, Abilian, and bTactic, aiming to foster autonomous European digital infrastructure.

Euro-Office aims to handle common file formats seamlessly, minimize migration friction, and avoid trademark constraints through open licensing and transparent development.

Success will hinge on the tech preview’s compatibility with Microsoft formats and ease of migration for large administrations with established workflows.
