Features
Manage dozens of SSH sessions simultaneously in a tiled, tabbed interface. Send commands, passwords, and scripts to hundreds of servers at once — mass login, mass sudo, mass anything.
No reimplemented SSH stack. TunnelRAT wraps your system's native ssh binary — so sudo, tmux, certificates, ProxyJump, and ~/.ssh/config all just work, exactly like your terminal.
Import your existing SuperPutty Sessions.XML in one click and pick up right where you left off — session groups, color coding, and all. Finally, SuperPutty for Linux.
Stored passwords delivered via atomic PTY writes — not character-by-character typing that breaks on special characters. SSH login, sudo, su, and key passphrases all handled natively.
Save your entire session arrangement — split panes, open sessions, active tabs — as a named layout. One click to restore your full workspace exactly as you left it.
Choose exactly which open sessions receive each broadcast command. Target all, target a group, or pick individually. Your commands go exactly where you want them.
Full theme system, configurable hotkeys, drag-to-tile split panes, scrollback history, dynamic tab titles, and an active open source community. This is your daily driver, not a demo.
Powered by xterm.js — full color support, unicode, scrollback, and resize handling that behaves exactly like your terminal. No visual quirks, no rendering surprises.
TunnelRAT runs entirely on your local machine. Nothing gets installed on your servers — no agents, no daemons, no footprint. Just standard SSH, exactly as intended.
