## What it is
Mosh is a remote terminal application that replaces interactive SSH sessions with a UDP-based protocol that survives roaming, IP changes, sleep, and intermittent connectivity. It provides intelligent speculative local echo so typing feels instant even on high-latency or lossy links.

## Use cases
- keep a terminal session alive while switching between Wi-Fi and cellular
- resume a remote shell after laptop sleep or network drop
- get instant typing feedback over high-latency SSH connections
- work on a remote server over spotty or lossy networks
- roam between IP addresses without dropping the terminal session

## When to choose
- you need interactive remote shells on mobile or unreliable networks
- your SSH sessions drop when changing networks or waking from sleep
- typing lag over long-distance links makes SSH painful
- you want a terminal that works with full-screen apps like vim or emacs on bad links

## When to avoid
- you need X forwarding or port forwarding
- you need non-interactive uses like scp, tunnels, or automation scripts
- your environment is not UTF-8
- you cannot open UDP ports on the server or firewall
