Chuchu is a native Android SSH client built on libghostty — the terminal rendering engine behind the Ghostty desktop emulator. It gives you a full, responsive terminal on Android with genuine VT emulation: resize, scrollback, modifier keys, mouse actions, and image display via the Kitty image protocol. Instead of a web-view or a thin wrapper, Chuchu renders every character natively on-device.Documentation Index

Transport types
Chuchu supports three ways to reach a remote host:| Transport | When to use |
|---|---|
| SSH | Standard SSH over TCP — works with any sshd-compatible server |
| Tailscale SSH | Connect through your Tailscale mesh network using a Tailscale IP or MagicDNS name |
| Mosh | UDP-based transport that survives network changes and high-latency connections |
