Euro-Office, Europe's Bet on Office Software Sovereignty

Published on April 06, 2026 | Translated from Spanish

A consortium formed by Nextcloud, Ionos, and Proton has presented Euro-Office, an office suite based on OnlyOffice. This development seeks to offer a European alternative to solutions like Microsoft Office, prioritizing control over the code and data. The initiative responds to the EU's digital sovereignty strategy. A preliminary version is on GitHub, with the stable version scheduled for the summer.

Technical base, licenses, and roadmap 📄

Euro-Office is built on the open-source core of OnlyOffice, ensuring compatibility with DOCX, XLSX, and ODF formats. The project adds specific integrations and is deployed on infrastructure under European jurisdiction. The licensing model and management of contributions to the base code are key aspects under development. The goal is to create an ecosystem maintained and controlled by European entities.

Goodbye to Clippy, hello to digital bureaucracy 🧾

While some miss the clip-shaped assistant, Euro-Office promises an authentically European experience. Imagine an assistant that, instead of suggesting fonts, reminds you to comply with GDPR before saving a document. Or that the toolbar includes a button to generate reports in the 24 official languages of the EU, with the same efficiency as an administrative procedure. Digital sovereignty has its own pace.
