Euro-Office Launches Open Office Suite for Windows, Mac, and Linux
Official distribution via Nextcloud Office arrives on desktops with support for DOCX, XLSX, and ODF, aiming to reduce Europe's dependence on Microsoft 365
Euro-Office has finally gained desktop installation packages. The open-source office suite, officially launched in June 2026, can now be installed on Windows (x86 and ARM), macOS (Apple Silicon), and Linux (DEB and RPM) in the form of Nextcloud Office Desktop.
The official distribution is led by Nextcloud, a German organization founded in 2016 and one of the participants in the Euro-Office project. The tool is free and allows editing of text documents, spreadsheets, presentations, and PDFs, with support for Microsoft's proprietary formats (DOCX, XLSX, and PPTX) and the open OpenDocument standards (ODT, ODS, and ODP).
The architecture behind the name
The confusion between Euro-Office and Nextcloud Office has a technical explanation. Nextcloud Office already existed as a solution based on Collabora Online for browser-based use. Now, the foundation becomes Euro-Office, which in turn is a fork of OnlyOffice.
Euro-Office is the community version, aimed at developers and organizations. Nextcloud Office Desktop is the official distribution packaged for immediate installation. The project has a stated mission to reduce European countries' dependence on United States technologies — although it can be used by people and organizations anywhere in the world.
Why another suite
LibreOffice already occupies the space of an open alternative to Microsoft Office. Euro-Office's bet is different: it is born from a European consortium with governance focused on digital sovereignty, rather than merely as a global community project.
The suite is one of the efforts to make the continent less dependent on Microsoft 365 in the public and private sectors. The availability of native packages for the three main operating systems eliminates the barrier of browser-based installation, which limited adoption in corporate and government environments.
Practical Impact
Technically, the OnlyOffice fork preserves compatibility with Microsoft Office formats, which reduces migration friction in environments already operating with DOCX and XLSX. The community base allows European developers to audit and modify the code, something unfeasible in proprietary suites.
Operationally, the arrival of packages for Windows ARM64 is strategic: it follows the migration of corporate laptops to Arm processors. For European public organizations, the suite offers an adoption route with no licensing costs, with governance based on the continent itself.
