FilePort Pro vs ST Explorer

FilePort Pro is a browser-based FTP and SFTP client for connecting to servers, browsing files, and transferring them without installing software. Its file list shows folders, sizes, types, and modification times with sorting and breadcrumb navigation. Users can upload multiple files, drag and drop, download files, or package a folder as a ZIP archive; each transfer shows byte-counted progress. For SFTP, the client displays and remembers a server host-key fingerprint and blocks reconnection after a key change until confirmation. Credentials pass through the service server, remain in memory during the session, and are not written to disk, stored in a database, or logged. Sessions end on disconnect or after about 15 minutes idle. The Free plan costs nothing and allows 4 GiB transfers, two concurrent sessions per IP, and no saved connections. Pro costs $5 a month and adds automatic resume, a 64 GiB limit, and an encrypted saved-connections vault. The service recommends SFTP because FTP is unencrypted by design.

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.
