FileZilla vs Cyberduck

FileZilla supports the core file transfer protocols: FTP, FTPS (FTP over TLS), and SFTP (SSH File Transfer Protocol). These cover the vast majority of traditional server administration needs. However, FileZilla does not support cloud storage services like S3, WebDAV, or any consumer cloud platforms, limiting it to server-based file transfers only.

Cyberduck handles file transfers efficiently and supports resume on interrupted transfers. However, it doesn't offer the same level of queue management granularity as FileZilla. Transfers are processed sequentially or with limited parallelism, and there isn't the same level of control over bandwidth allocation and connection limits.

FileZilla's interface is functional but feels non-native on macOS. Built with wxWidgets, it has a distinct cross-platform appearance that doesn't match macOS design conventions. The dual-pane layout is efficient for FTP work but looks dated compared to native Mac applications. It supports keyboard shortcuts but doesn't integrate with macOS features like Quick Look, Services, or Handoff.

FileZilla supports FTPS (TLS encryption) and SFTP (SSH encryption) for secure file transfers. It validates server certificates and supports client certificates for authentication. The master password feature protects stored credentials. However, FileZilla has faced criticism in the past for bundling adware in its installer (Windows only) and storing passwords in plain text XML files.

FileZilla has basic remote file editing support—you can configure an external editor, and FileZilla will download the file, open it in the editor, and re-upload when saved. However, the implementation is rudimentary compared to Cyberduck's approach, and it doesn't work reliably with all editors.

FileZilla includes directory comparison that highlights differences between local and remote directories by file size and modification date. Synchronized browsing navigates both panes simultaneously. The comparison view helps identify files that need updating, though it's not a full-featured sync tool.

Cyberduck offers directory synchronization that can upload changed files, download changed files, or mirror directories bidirectionally. The comparison is based on file size, modification date, or checksum. While functional, it's not as visually prominent as FileZilla's side-by-side comparison view.

FileZilla is primarily a GUI application and doesn't include a command-line interface. For scripted file transfers, users need to use separate tools like lftp, sftp, or curl. This limits FileZilla's usefulness in automation and CI/CD pipelines.
