Cyberduck

Cyberduck is a graphical client for macOS and Windows that lets users browse and manage files on a wide range of remote servers and cloud storage services. It supports standard protocols such as FTP, SFTP, WebDAV, and SMB, as well as object‑storage APIs including Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure, Google Cloud Storage, and services like OneDrive, Google Drive, Dropbox, Box, Nextcloud, ownCloud, and DRACOON.

The application provides an easy‑to‑use interface for creating and saving connection profiles for popular hosting providers, and it integrates with external editors so files can be opened, edited, and saved directly on the remote location. It also offers client‑side encryption through Cryptomator‑compatible vaults, allowing users to secure data before it leaves the client.

Cyberduck targets developers, system administrators, and anyone who needs to transfer or synchronize files across diverse storage back‑ends without using separate tools for each service. Its stable, free‑tier release emphasizes broad protocol coverage and straightforward file‑management workflows.
