ST Explorer review
A free, focused SFTP client with practical browsing, transfer, and SSH features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ST Explorer is a native desktop SFTP client for browsing remote files and managing transfers. It is aimed at users who want a free, focused tool for SFTP access across Windows, macOS, and Linux. The interface supports icon, list, and Finder-style column views, while drag-and-drop uploads from Windows Explorer and native clipboard integration keep common file operations straightforward. An integrated tabbed SSH terminal adds command-line access within the same application.
Its strongest area is day-to-day transfer control. A live transfer progress panel provides visibility into active operations, and server-side copy supports remote-to-remote moves without requiring the files to pass through the local machine. Keyboard shortcuts cover file operations and filtering. SSH key support and known_hosts host-key pinning add authentication and host-verification options for users managing SFTP connections. The published feature set remains centered on file browsing and transfers, so teams looking for automation or synchronization should consider a more specialized alternative.
ST Explorer is distributed as a standalone Windows executable and is free under the MIT license. The vendor states that macOS and Linux compatibility is available by building from source, making the platform experience more direct on Windows than on the other supported systems. That setup model suits technically comfortable users who value open-source software and a focused feature set. Choose ST Explorer for straightforward SFTP transfers, remote file management, SSH key support, and a native desktop workflow; choose another tool if you need broader protocol coverage, built-in automation, or synchronization features.
