Euro-Office (GA June 2026) is an open-source web office you add to Nextcloud, backed by a consortium including IONOS, Nextcloud and Open-Xchange. Email.eu is a different shape: the complete workspace — mail server included — run as one product by one accountable company.
Euro-Office details are from the consortium's public launch materials (nextcloud.com), general availability June 9, 2026 — it is new, and this comparison will be updated as it matures. Last updated June 2026. Euro-Office, Nextcloud, IONOS and Open-Xchange are trademarks of their respective owners, none of which are affiliated with or endorse Email.eu.
One subscription. Everything included.
Mail · Calendar · Contacts · Drive · Docs, Sheets & Slides · Wiki · Chat · Video meetings · Migration engine · SSO & 2FA · Hands-on onboarding
No add-on ladder — no Copilot tier, no Gemini tier, no storage upsell to make the entry plan usable.
Euro-Office is good for Europe, and we mean that — a credible open-source office suite makes the whole category real. But note what you're buying: an editor component. To run a company on it you still assemble Nextcloud, a mail server, video meetings, identity and backups — yourself or through a hoster — and when something breaks, the question is which vendor in the coalition owns the problem.
Email.eu is the assembled result: one login, one bill, one DPA, one company accountable for the whole thing. Same European open-source foundations — Stalwart, Bulwark, La Suite Meet, Authentik — already integrated, operated and onboarded by hand.
If you have the team to run Nextcloud and want full open-source control with no per-seat licence, the Euro-Office stack is a legitimate choice — that DIY freedom is something a hosted product can't give you. Email.eu is for companies that want the sovereign workspace as a finished product, with a roadmap we publish honestly and a human who picks up the phone.
