Euro-Office Launches Desktop App Amid Open-Source Software Controversies
The European open-source project Euro-Office is releasing a dedicated desktop application for Windows, macOS, and Linux to provide an independent alternative to Microsoft 365, according to announcements.
While the project aims to reduce reliance on US-based IT infrastructure, its technical foundations have drawn scrutiny. According to project disclosures reported by WinFuture, Euro-Office is built on the source code of OnlyOffice, a platform with development roots in Russia. Furthermore, the Document Foundation has criticized the suite’s reliance on Microsoft’s proprietary OOXML file formats rather than the open Open Document Format standard.
Desktop Application and Offline Features
The new desktop software marks a significant expansion for Euro-Office, which previously operated exclusively through web browsers. According to project announcements, the local client delivers faster processing speeds, improved document previews, and advanced filtering options. Alongside core office tools, the updated platform introduces shared workspaces for project groups, calendar integrations with enhanced room-finding capabilities, relational spreadsheet columns, and a local optical character recognition assistant for images and documents. Users will be able to download the installation files directly from participating partner platforms.
Licensing Disputes and Code Origins
Despite its positioning as a sovereign European solution, Euro-Office faces ongoing questions regarding its pedigree. Analyses cited by WinFuture indicate that substantial portions of the underlying code originate from developers operating in Russian time zones. Additionally, project adjustments prompted a public reprimand from Ascensio System SIA, the developers of OnlyOffice, over brand and AGPL license compliance. The initiative originally formed to build compliant data infrastructures for European schools and public administrations, but it continues to navigate these architectural and legal hurdles as it rolls out local clients.
