N3XShell — terminal, tunnels and files over SSH
A lightweight native Windows and macOS app for managing SSH servers. Use a full terminal in tabs, create secure tunnels and move files both ways with a dual-pane SFTP commander. Secrets stay in the system vault.

What N3XShell can do
Server list
Organize hosts into folders, label them with tags and colors, and find the one you need instantly with search.
One-click connect
Double-click opens a session in a new tab. Multiple parallel connections, fast switching and reconnect.
Built-in terminal
A full terminal emulator (xterm) with PTY, colors and resizing support — just like a native console.
Password & key auth
Sign in with a password or a private key (with passphrase). Standard OpenSSH keys supported.
Secrets in the system vault
Passwords and key passphrases go into Windows Credential Manager, not a config file. Host configuration stays local.
Server key verification
Trust on first use (known hosts) and a warning when a server key changes — protection against MITM attacks.
SSH tunnels without a console
A visual ssh -N -L equivalent for HTTP, HTTPS and TCP. Dynamic port, autostart, reconnect, traffic counters and a safe 127.0.0.1-only listener.
Dual-pane SFTP commander
Browse local and remote files side by side, upload and download with live progress, calculate folder sizes on demand, and safely manage items.
