Nextcloud
Self-hostable productivity suite. Docs, calendar, contacts and more, all fully European.
Quick facts
Docs, calendar, contacts, talk and file sync all live under one self-hosted roof, so you can genuinely replace a chunk of Google Workspace with a single install. A huge app-store ecosystem covers everything from Kanban boards to a password manager.
Running it well takes real server admin know-how – updates, backups and performance tuning are on you unless you pay for hosted or enterprise support.
Why does it score 87?
Incorporated in Stuttgart, Germany – a full EU member state.
Backed by investors including Deutsche Telekom, but no single non-EU parent company holds a controlling stake.
Nextcloud runs on infrastructure you control yourself – your own server or a hosting provider of your choice – with nothing routed through a Nextcloud-run cloud.
Fully open source and GDPR-compliant, one of the most thoroughly reviewed self-hosted platforms around.
