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

说明与用途

一个基于浏览器的文件传输工具，使用 WebRTC 和 PeerJS 进行直接点对点传输，全部在单个 HTML 文件中实现。

问题

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

结果

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

工作流

• 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

证据

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.

来源

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

来源

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.
