Nextcloud gives you access to all your files wherever you are.
Where are your photos and documents? With Nextcloud you pick a server of your choice, at home, in a data center or at a provider. And that is where your files will be. Nextcloud runs on that server, protecting your data and giving you access from your desktop or mobile devices. Through Nextcloud you also access, sync and share your existing data on that FTP drive at the office, a Dropbox or a NAS you have at home.Get started
Share with others on your terms.
The easy web interface allows you to share files with other users on your server, to create and send password protected public links, to let others upload files to your cloud and to get notifications on your phone and desktop when a user on another cloud server shares files directly with you. And you can do all these things from the desktop or mobile clients, too.Share with Nextcloud

With Nextcloud, system administrators can control and direct the flow of data between users on or between servers. Rule based file tagging and responding to these tags as well as other triggers like physical location, user group, file properties and request type enables administrators to specifically deny access to, convert, delete or retain data following business or legal requirements. Nextcloud puts you in control of your data and keeps it safe.Workflow handling

External storage, securely encrypted
The external storage feature of Nextcloud gives you access to your data wherever it is. Nextcloud can access files stored with a wide variety of popular cloud service providers such as Amazon, Google and Dropbox, but you can also access them using standard protocols such as NFS, (S)FTP, WebDAV and more.
The Encryption App can encrypt data at rest for both local and remote storage, protecting data stored on networks outside of your infrastructure. Keys can be handled by an external key management server or stored locally, on the server. Nextcloud will keep your data where it is and retrieve it over a secure communication channel whenever you need to access it.Learn more
