About this app

CrabbyShell SSH is a modern, fast terminal client built for Android. Connect to your servers over SSH, Mosh, or Telnet, talk to hardware over Serial (USB or Bluetooth), or launch a local shell — all from one app.

Designed for developers, sysadmins, and IT professionals who need reliable remote access on the go.

Easy Migration
