Euro-Office 1.0 reaches its first stable release as an open-source, browser-based alternative positioned against Microsoft 365 and Google Workspace. Backed by a coalition of EU-based organizations and “Euro-Stack” participants, the project promotes the idea of “digital sovereignty,” aiming to let European organizations host office capabilities on infrastructure in the EU under EU frameworks, while keeping a Microsoft-like editing experience.

Multiple sources describe Euro-Office as an integration component rather than a complete standalone office suite. The software provides document editing, while storage and related features such as navigation, permissions, and sharing are handled by the platform it is deployed with (for example, services like Proton Docs, Nextcloud, or OpenProject). Although it can be installed on a Linux server, early adopters and packaged offerings are described as web-based deployments.

The release is accompanied by open-source infighting. The Document Foundation (TDF), which steward LibreOffice, criticizes Euro-Office for defaulting to Microsoft’s OOXML document format. TDF argues this default reinforces Microsoft “lock-in,” stating that “compatibility is not sovereignty.”
