FileZilla Client vs ST Explorer

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.

ST Explorer is a free native SFTP client for browsing and transferring remote files on Windows, macOS, and Linux. It offers icons, list, and column views, plus an integrated SSH terminal that supports multiple tabs on the same connection. Transfers include drag-and-drop uploads, clipboard uploads, server-side remote-to-remote copies, and a live progress panel. On Windows, files copied in Explorer can be pasted into ST Explorer using native clipboard integration. The site says host key pinning uses known_hosts with TOFU, and describes the app as having no telemetry or phone-home behavior. ST Explorer is open source under the MIT license and is approximately 12 MB as a single executable without an installer. The listed Free plan costs nothing; it specifies Windows 10/11 with WebView2, while macOS and Linux builds are available from source. SSH key authentication is supported. Stivetec makes the app and links to GitHub for issue reports.
