Cyberduck vs FileZilla Client

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.

FileZilla Client is a free FTP solution for file transfers, with support for FTP, FTPS, and SFTP. It is available for Linux, macOS, and Windows. The project presents FileZilla Client separately from FileZilla Server, FileZilla Pro, and RemoteDrive, so those products should not be assumed to be part of the Client. Documentation includes installation instructions for Windows, Linux, and Mac OS X, plus tutorials, usage guidance, and help with connection, transfer, and network configuration problems. The Wiki also includes guidance for key-based SFTP authentication. Support resources include a community forum, Wiki, FAQ, support section, and contact page. The project site links to source code, an issue tracker, nightly builds, translations, and version history. FileZilla Pro is a separate product whose overview lists support for cloud services including S3, Google Drive, and OneDrive. No paid price or billing schedule is stated for the Client, and no free-tier limits are stated.
