Cyberduck is an open source FTP, SFTP, WebDAV, Mosso Cloud Files and Amazon S3 browser for the Mac. It features an easy to use interface with quickly accessible bookmarks.

The outline view of the browser allows to browse large folder structures efficiently and you can quickly preview files with Quick Look. To edit files, a seamless integration with several external editors makes it easy to change content quickly. Both Amazon CloudFront and Cloud Files from Rackspace can be easily configured to distribute your content in the cloud. Many OS X core system technologies such as Spotlight, Bonjour and the Keychain are supported and a large number of translations makes you feel at home.

Cyberduck features the same intuitive interface for both FTP and SFTP browsing and is now Mac-only, with a completely rewritten user interface using the Cocoa framework. You can open connections to multiple servers, thanks to its document-based interface. A Simple Favorites manager allows you to store frequently used servers. Drag and drop is supported for both downloading and uploading files. Just drag a file or folder from the Finder to the browser window or vice versa to start the transfer. File deletion and renaming, checking, and changing of permissions is possible with a Finder-like info panel. Rendezvous also is supported.

Built around a gorgeous, newly overhauled interface, this free, GPL-licensed FTP browser is a lean, mean file-managing machine. CyberDuck can communicate with standard FTP volumes as well as the more secure SFTP. The application easily manages bookmarks with an OS X-styled drawer. We like the quick-connect drop-down, which allows you to pop into recently accessed or bookmarked servers in a snap. We generally found both up and downstream file transfers to be speedy. While Cyberduck can be seen as limited in terms of functionality due to its entry-level nature, the program handles basic tasks with ease.
