Nextcloud is a suite of client-server software for creating and using file hosting services. Nextcloud application functionally is similar to Dropbox, Office 365 or Google Suite . Unlike Dropbox, Microsoft or Google Nextcloud does not offer off-premises file storage hosting. Nextcloud is free and open-source, which means that anyone is allowed to install and operate it on their own private server devices. In contrast to proprietary services like Dropbox, the open architecture allows adding functionality to the server in the form of applications and enables users to have full control of their data.
