Cyberduck is a free and open-source FTP, SFTP, WebDAV, S3, Backblaze B2, and Azure Blob Storage client for macOS and Windows. Essentially, it[SQ]s a program that lets you easily transfer files to and from servers using various internet protocols. Think of it as a graphical user interface (GUI) that makes interacting with remote servers much simpler than using command-line tools.

It provides a familiar file browser-like experience, allowing you to drag and drop files, create folders, and manage files on remote servers just as you would on your local computer. This makes it a popular choice for web developers, designers, and anyone who needs to regularly transfer files to and from remote servers.
