Xcasca provides a lightweight SSH and SFTP client with a terminal‑focused interface that runs on macOS, Windows, Linux, iOS, and Android. It offers a pure terminal emulation experience and a split‑pane view that lets users see the command line and remote file system side by side, facilitating simultaneous command execution and file management.

The client supports drag‑and‑drop file transfers via SFTP and can connect to cloud storage services such as AWS S3 and Google Cloud Storage. Sessions can be organized, saved, and quickly reconnected, and users can forward ports through SSH tunnels for secure remote access.

Data synchronization across multiple devices is available through a paid plan, which also unlocks advanced features like cloud storage file transfers and enhanced session properties. The free tier supplies the core SSH and SFTP functionality without time limits.
