Cyberduck is an FTP client (also with SSL), SFTP, WebDAV, Windows Azure Storage, Swift (OpenStack), Amazon S3, Google Cloud Storage, Rackspace Cloud Files, Backblaze B2, Google Drive and Dropbox, with a simple graphical interface, built from scratch for easy file transfer. It can only be used with the drag-and-drop method. Cyberduck allows you to connect to multiple servers at once and exchange data simultaneously with all servers.

The speed and number of transfers can be specified by the user, as well as the order and encoding of characters used by the server. Once the connection is broken, the transfer can be resumed, regardless of whether it was downloading or uploading files. Connections can be saved as bookmarks.

Passwords can be stored by the program together with bookmarks, it is possible to connect to the resources found using Bonjour, setting up notifications about the end or error of the transfer and extension of the program.
