A safe home for all your data
Nextcloud provides a file sync & share solution that respects your privacy and is fully open source. Sync clients are available for all major platforms. Nextcloud comes with a rich ecosystem of apps including Contacts, Calendar, Video calls, Mail, Newsreader and much more.
Nextcloud originated as a fork of ownCloud. It is preferred because ownCloud has an "open core" product model and lacks some security features Nextcloud has.
