## What it is
Magic Wormhole is a Python library and command-line tool for securely transferring arbitrary-sized files, directories, or short text between computers. Endpoints pair via short, single-use, human-pronounceable 'wormhole codes' with end-to-end encryption.

## Use cases
- send a file to a friend without a cloud service
- transfer files between two computers securely
- copy a directory from one machine to another over the internet
- share a text snippet or password between devices
- move files between remote servers without scp keys

## When to choose
- you need ad-hoc, encrypted peer-to-peer file transfer with no accounts
- you want a simple CLI with short human-readable pairing codes
- you need a library to embed secure transfer into another tool

## When to avoid
- you need continuous folder sync or backup rather than one-shot transfers
- you require a GUI-first experience (though ecosystem clients exist)
- you cannot reach the public mailbox server or transit relay and don't want to self-host them

## Facets
- artifact type: cli-tool
