PairDrop

PairDrop is a web-based, cross-platform file sharing app inspired by Apple’s AirDrop and based on Snapdrop. It enables peer-to-peer transfers between devices on the same network, and also supports internet transfers via paired devices or temporary public rooms.

Key Features

• Peer-to-peer file and text transfer between nearby devices using a modern web browser
• Persistent device pairing using a 6-digit code or QR code to reconnect across networks
• Temporary public rooms (code or QR) for quick sharing over the internet
• Works across platforms (desktop and mobile) and can be installed as a Progressive Web App
• Transfer acceptance flow, progress indicators, and automatic download behavior where supported
• Multi-file transfers with optional ZIP bundling for downloads
• Customizable display name and basic UI enhancements (previews, theming)

Use Cases

• Quickly send photos, videos, documents, or links between phone and laptop without cables
• Share files with friends or colleagues on public Wi-Fi or across different networks using rooms
• Run a private, self-hosted local sharing page for households, teams, or labs

Limitations and Considerations

• WebRTC connectivity can depend on network conditions; some scenarios may require TURN/STUN configuration for reliable traversal
• Transfers require the recipient to be available and to accept the request; it is not designed for asynchronous “dropbox-style” sharing

PairDrop is a practical, lightweight alternative to native device sharing tools, offering an AirDrop-like experience directly in the browser. It fits well for fast, privacy-friendly, ad-hoc transfers both on local networks and across the internet.
