Cyberduck is an open-source client for FTP and SFTP, WebDAV, and cloud storage (OpenStack Swift, Amazon S3, Backblaze B2 and Microsoft Azure), available for macOS and Windows (as of version 4.0) licensed under the GPL. Cyberduck is written in Java and C# using the Cocoa user interface framework on macOS and Windows Forms on Windows. It supports FTP/TLS (FTP secured over SSL/TLS), using AUTH TLS as well as directory synchronization. The user interacts with the user interface (GUI), including file transfer by drag and drop and notifications via Growl. It is also able to open some files in external text editors.

Cyberduck includes a bookmark manager and supports Apple's Keychain and Bonjour networking. It supports multiple languages including English, Catalan, Czech, Chinese (Traditional and Simplified), Danish, Dutch, Finnish, French, German, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian, and Welsh.
