Graphical SFTP client and terminal emulator with helpful utilities
...Muon provides functionality similar to web-based control panels but, it works over SSH from the local computer, hence no installation is required on the server. It runs on Linux and Windows. Muon has been tested with several Linux and UNIX servers, like Ubuntu server, CentOS, RHEL, OpenSUSE, FreeBSD, OpenBSD, NetBSD, and HP-UX. The application is targeted mainly towards web/backend developers who often deploy/debug their code on remote servers and not overly fond of complex terminal-based commands.

It runs on Linux and Windows. Snowflake has been tested with Ubuntu server, CentOS, RHEL, OpenSUSE, FreeBSD, OpenBSD, NetBSD and HP-UX
