Why Termlet
- Your AI never sees passwordsAI tools get the output; passwords and keys stay in Termlet.
- Dangerous commands ask firstrm -rf, shutdown and the like run only after you approve.
- Only the hosts you allowOff by default, allowed host by host, every call logged.
- Everything else you needSplit panes, two-pane SFTP, tunnels; import from Xshell and more.
Let AI work on your servers, safely
Turn on the command-line tool in Settings and run termlet skill install once; Claude Code then works through termlet instead of ssh.
Dangerous-command rules guard against mistakes; they can be bypassed and are not a security boundary, so give the command-line tool a low-privilege account.
termlet ls
| ID | NAME | ADDRESS | USER | PROTOCOL |
|---|---|---|---|---|
| h_3k9x2m4p8q1r7s5t | web-01 | 10.0.0.5:22 | deploy | ssh |

termlet exec web-01 "systemctl is-active nginx"
active
termlet upload web-01 ./app.tar.gz /tmp/
Uploaded 12.4 MB → /tmp/app.tar.gz (1.8s)
termlet exec web-01 "sudo systemctl reboot"
# Termlet asks: the command-line tool wants to run a dangerous command on “web-01”
# You click “Deny”: nothing runs, exit code 4
