German office suite (TextMaker, PlanMaker, Presentations) with strong Word/Excel/PowerPoint compatibility. Includes Duden dictionary and proofreader. Subscription model (Office NX) plus a free version.

Free open-source office suite from The Document Foundation. Native ODF, broad format support. Mature on Linux/macOS/Windows; mobile story is weak.

Office suite with the highest fidelity to Microsoft formats among open-source options. Browser-based, Nextcloud/ownCloud integrations, self-hostable Document Server. Headquartered in Latvia.

Browser-based office editing inside Nextcloud, powered by Collabora Online (LibreOffice engine). Self-hosted, end-to-end under your control. Nextcloud GmbH is German.

End-to-end encrypted collaborative office suite (rich text, sheets, slides, code, kanban). French project by XWiki. Server cannot read your content.

Affordable German office suite (text, spreadsheet, presentations). Built on the SoftMaker engine. Windows-only.

KDE office suite with integrated graphics tools. Linux-first. Niche but interesting for designer workflows.

Open-source, browser-based fork of OnlyOffice positioned as a European alternative to Microsoft Office and Google Workspace. Early stage.

Enterprise LibreOffice that runs in the browser. The engine behind Nextcloud Office; also stands alone. UK-based but EU-deployable.

End-to-end encrypted collaborative documents from Proton (Swiss). Part of Proton Drive. Newer; rich-text-first, no spreadsheets/slides yet.

Reference baseline. Industry standard but US-jurisdiction (CLOUD Act). Listed for honest comparison, not as an EU alternative.
