European Consortium Launches Euro-Office, an Open-Source Office Suite Based on OnlyOffice Code

• April 6, 2026

A coalition of European technology companies has introduced Euro-Office, a new suite of office applications developed using the open-source codebase of OnlyOffice. The consortium behind the project includes prominent names such as Nextcloud, Ionos, and Proton.

Promoting European Software Independence and Open-Source Development

Euro-Office is positioned as a key initiative to enhance software sovereignty within Europe by providing an alternative office productivity platform grounded in open-source principles. By leveraging OnlyOffice’s code, the project aims to offer a robust, interoperable solution that respects user control and data privacy.

The initiative has stimulated broad discussion across the tech community about issues surrounding software sovereignty, licensing, and the trustworthiness of open-source ecosystems. Given the involvement of well-established companies known for their secure and privacy-focused services, Euro-Office reflects a broader European effort to reduce reliance on non-European software products.

The suite is designed to integrate seamlessly with cloud and collaboration platforms, offering tools necessary for document editing, spreadsheet management, and presentations. As a collaborative project, it relies on shared resources and development efforts from the consortium members, each bringing expertise in privacy, cloud infrastructure, and secure communication.

While the project details regarding deployment and commercial strategy have not been widely publicized, Euro-Office represents a strategic step toward fostering a digital infrastructure that aligns with European values of transparency and autonomy.

This development may resonate particularly with governments and enterprises seeking to align their IT environments with regional security and compliance standards, further encouraging adoption of open-source alternatives in productivity software.

Euro-Office, a new European office suite built on OnlyOffice code, aims to strengthen software sovereignty and open source trust.
