Nextcloud is a self-hosted workspace that brings files, calendars, contacts, chat and document editing together under your own control. Instead of handing your data to a large cloud provider, you run it on your own server or a provider you trust. It is well suited to families, teams and organisations that want everyday collaboration without giving up privacy.
