German-developed, self-hostable file sync, share, and storage platform used as a private alternative to Dropbox and Google Drive.

Nextcloud is an open-source content collaboration platform centered on file storage, sync, and sharing, which organizations can self-host or run via Nextcloud-certified providers to keep full control of their data. It targets businesses, public institutions, and privacy-conscious individuals wanting Dropbox- or Google Drive-like functionality without US cloud providers.

Beyond core storage and sync, it offers desktop and mobile clients, file versioning, end-to-end encryption options, and collaborative document editing. This entry covers Nextcloud’s core Files and storage-and-sync product, distinct from the separately listed Nextcloud Talk, the suite’s video and chat module.
