FileSync: An end-to-end encrypted P2P file distribution tool
FileSync is an open-source real-time file transfer tool based on WebRTC technology. It breaks the limitations of traditional cloud storage or file transfer tools that require account registration and client installation, allowing users to quickly distribute files between different devices simply through a browser.
Core functions and features
- Flexible distribution models: It supports one-to-one transmission, as well as one-to-many or many-to-many real-time file distribution.
- Zero-barrier to use: No installation required, cross-platform compatible, and can be operated through a web interface.
- Convenient collaboration and sharing: It supports creating room links, allowing users to quickly invite others to join via QR code, and offers optional password protection.
- High degree of privatization: The code is completely open source, supports one-click deployment with Docker, and can be configured with automatic HTTPS certificates.
Working principle and safety
FileSync adopts WebRTC The agreement was passed PeerJS Establish point-to-point (P2P) direct connections between devices. During the transmission process,PeerJS Server 仅承担信令交换与打洞协助等初始建链工作，并不接触或存储任何文件内容。
由于所有数据均通过 端到端加密 直接在发送端与接收端之间传输，不经过中间存储服务器，从而在物理层面保障了数据的隐私与安全。
快速使用指南
- 创建房间： 发起者创建传输房间，生成唯一的分享链接或二维码。
- 权限控制： 根据需求设置访问密码以增强安全性。
- 接收文件： 接收方加入房间后，即可实时看到传输进度并在界面中下载文件。
部署与获取方式
对于有私有化部署需求的用户，可以通过 GitHub 获取源码并使用 Docker 进行快速部署，使其在自有域名或内网环境中运行。
