Very soon there will be Office EU - Europe's Open-Source Productivity Suite
Office EU is an open-source content collaboration platform, which means the code can be inspected and audited by anyone. In practice, it supports transparency and reduces vendor lock-in compared to closed platforms.
Office EU provides desktop sync clients for Windows, macOS and Linux, plus mobile apps, so files can follow you across devices. You can also use the web interface if you don't want to install anything.
Office EU is a complete cloud-based office suite (like Microsoft 365 or Google Workspace) that is 100% European-owned and runs entirely on European infrastructure.
Office EU includes all the essential productivity apps for documents, spreadsheets, presentations, file storage, email, calendars, and video meetings.
