Euro-Office
FOSS office suite based on OnlyOffice
From Wikipedia, the free encyclopedia
Euro-Office is a FOSS office suite and collaborative software platform, based on software from a more restrictively licensed office suite called OnlyOffice, that provides editors for documents, spreadsheets, presentations, and PDFs. The software includes web-based applications designed for document creation, editing, and collaborative work.[3]

History
The project began in March 2026 in a quest to gain full independence from Microsoft Office being used in EU public computers.[4][5][6] The project is a collaboration between various organizations, companies, and open source developers. The original collaborators were IONOS, Nextcloud, Eurostack, XWiki, OpenProject, Soverin, Abilian and BTactic, with Office EU and Open-Xchange joining the project soon after its announcement.[7][8]
One of the first changes made to the Euro-Office codebase was to remove licensing terms deemed to be "unenforceable and non-obligatory" additions to the GNU AGPL licence.[9] Three days later, the developers of OnlyOffice responded by publicly calling these changes a licensing violation.[10][11] Soon after, OnlyOffice announced it would be suspending its partnership with Nextcloud due to the conflict.[12]
In response to these accusations, statements were issued by Nextcloud Software,[13] the Free Software Foundation,[14] and legal experts[15] asserting that both the letter and the spirit of a free software license expressly prohibit the use of license addenda to revoke the freedoms guaranteed by the original license. In the case of the addenda to the GNU AGPL license introduced by the OnlyOffice developers, they contained mutually exclusive requirements (specifically, a simultaneous prohibition on altering branding and a prohibition on the use of the trademark). The position held by the creators of the GNU AGPL—as well as by legal experts—is that restrictive supplementary clauses may be omitted from the license during redistribution; this principle is explicitly stated in Clause 10 of the original GNU AGPL license.
The first stable version was released on 9 June 2026. It was reported that OnlyOffice's allegation of license violation had been resolved.[16]
Products
Similar to OnlyOffice, the Euro-Office ecosystem consists of several core applications and tools designed for document editing, collaboration, and workspace management.[citation needed] These include:
| Feature/Component | Description |
|---|---|
| Euro-Office Docs | The core document editing engine providing web-based editors for text documents, spreadsheets, presentations, PDF files, and fillable forms. It supports formats including DOCX, ODT, XLSX, ODS, PPTX, ODP, and PDF. The editors provide real-time collaborative editing with features such as comments, version history, track changes, document comparison, and built-in chat. Euro-Office Docs can be deployed on a private server or used through cloud services. |
Reception
Some supporters of the open source competitor LibreOffice, questioned some of the motives and logic concerning Euro-Office[17] in using Microsoft standards by indicating that by seeking to be fully Microsoft compatible, Euro-Office is inadvertently reinforcing Microsoft going forward as the global dominant standard rather than supporting development of competing standards.[18][19][20]
