I built a free AirDrop alternative in one HTML file with WebRTC and PeerJS

Описание и применение

Простой браузерный инструмент для передачи файлов между устройствами без электронной почты, использующий WebRTC и PeerJS.

Задача

Users need a simple way to transfer files between devices without email or cloud services.

Результат

A lightweight, free, browser‑based file transfer tool that eliminates the need for email or cloud services.

Рабочий процесс

• Open the HTML file on two devices
• Scan the QR code or enter the 6‑character code
• Drop files or text into the browser
• Data is sent directly over WebRTC
• Files are held in memory until the user saves them

Доказательства

Open it on two devices, scan the QR code (or type the 6-character code), and drop files or text. Data goes directly between browsers over WebRTC.

Источник

PeerJS's free public server is used only for pairing.

Источник

Known limits: pairing depends on the free PeerJS server, received files are held in memory until saved, and anyone with the code can connect while the tab is open.
