## What it is
pcp is a command-line peer-to-peer file transfer tool built on libp2p that transfers data directly between peers without relying on central servers. It uses DHT and mDNS for peer discovery and PAKE for password-based authentication.

## Use cases
- send files directly between two computers without a server
- transfer files between machines on the same local network
- share files without uploading to cloud storage
- peer-to-peer file copy between remote machines over the internet
- decentralized alternative to magic-wormhole or croc

## When to choose
- you want serverless, decentralized file transfer between peers
- you need to move files between machines on the same LAN or across the internet without a relay service
- you prefer libp2p-based tooling and are comfortable with an early-stage tool

## When to avoid
- you need production-grade security and performance guarantees
- you want a polished, actively maintained file transfer tool
- you need transfers through browsers or to non-technical recipients

## Facets
- artifact type: cli-tool
- maturity: experimental
- function: p2p, file-system, security, networking
- domain: files, privacy, networking
- platform: windows, cli, cross-platform
