## What it is
PairDrop is a browser-based, AirDrop-like file sharing app that transfers files peer-to-peer between devices on the same local network or over the internet via paired devices and temporary public rooms. It is an actively maintained fork of Snapdrop, built with Node.js, WebRTC, and WebSockets, and can be self-hosted or used at pairdrop.net.

## Use cases
- send files from phone to laptop without cables
- airdrop alternative for android and ios
- share photos between devices on local network
- transfer files between linux and windows
- send files over the internet without signup
- self-host a local file sharing service
- share files between devices behind a VPN or NAT

## When to avoid
- you need large-scale or asynchronous file distribution to many recipients
- you require cloud storage, file history, or access controls
- you need transfers between devices that cannot run a modern browser

## Facets
- artifact type: application
- maturity: active
- function: file-upload, websocket, p2p, self-hosted
- domain: files, web-development, cross-platform, privacy
- platform: browser, cross-platform, self-hosted
