Cyberduck vs lftp

Cyberduck is a libre server and cloud-storage browser for macOS and Windows. It connects to FTP, SFTP, WebDAV, SMB, OpenStack Swift, Google Cloud Storage, Amazon S3, Azure, Backblaze B2, OneDrive, SharePoint, Google Drive, Box, Dropbox, and other services. Transfers include drag-and-drop uploads and downloads, recursive directory transfers, resumable transfers, and direct copying between servers. It can synchronize local and remote directories and preview the files affected before acting. Users can edit server-side text or binary files with an external editor, and copy or open HTTP URLs; S3 support includes CDN and pre-signed URLs. Cryptomator integration provides client-side encryption, including encrypted filenames and files. SFTP supports strong ciphers, public-key authentication, and two-factor authentication. Passwords are kept in the system Keychain, and certificates are checked against its trust settings. The free software is GPL-licensed and does not require registration or an account. A personal registration key is listed at $10 a month, billed as a minimum contribution shown by the vendor; a separate registration key contribution is $10, paid once. Retaining modification dates is not supported for all protocols.

lftp is a free command-line file transfer program for Linux, with support for FTP, HTTP, FISH, SFTP, HTTPS, FTPS and BitTorrent. It can synchronize files, automate transfers and run queued jobs at set times. Its mirror command downloads or updates a directory tree; reverse mirror does the same by uploading to a server. Multiple files can transfer in parallel, and pget can use multiple connections for one download. lftp retries operations after non-fatal errors and can resume downloads from where they stopped. Unfinished jobs can continue in the background after you exit the program or close an xterm. FTPS and HTTPS rely on GNU TLS or OpenSSL, depending on how lftp was built. Downloads include source archives and Fedora RPM binaries. Release information differs across the project pages: the homepage lists 4.9.3, released on 2024-11-08, while the download page calls 4.9.2 the latest stable version. The author says they have little time to support lftp; the project lists two mailing lists.
