PairDrop

PairDrop: local file sharing in your browser. Inspired by Apple's Airdrop.

Developed based on Snapdrop

Differences to Snapdrop

Device Pairing

• Pair devices via 6-digit code or QR-Code
• Pair devices outside your local network or in complex network environment (public wifi, company network, Apple Private Relay, VPN etc.).
• Paired devices will always find each other via shared secrets even after reopening the browser or the Progressive Web App
• You will always discover devices on your local network. Paired devices are shown additionally.
• Paired devices outside your local network that are behind a NAT are connected automatically via Open Relay: Free WebRTC TURN Server

Improved UI for sending/receiving files

• The receiving peer must accept the request of files before they are transferred and downloaded automatically afterwords if possible
• Multiple files are downloaded as ZIP file
• On iOS and Android the devices share menu is opened instead of downloading the files
• Multiple files are transferred at one archive which shows the overall progress correctly
• The integrity of the files is checked on receive
• By zipping the files before sending, all metadata is preserved

Share Files Directly From Share / Context Menu

• Share files directly form context menu on Windows
• Share directly from share menu on iOS
• Share directly from share menu on Android

Other changes

• node-only implementation (thanks @Bellisario)
• automatic restart on error (thanks @KaKi87)
