QuickDrop

QuickDrop is a secure, fast, and serverless file transfer application. It enables direct file sharing between devices using WebRTC, ensuring privacy and efficiency without relying on centralized servers.

Features

• Serverless File Transfer: Files are transferred directly between devices using WebRTC.
• Secure: End-to-end encryption ensures your files remain private.
• Fast: Peer-to-peer connections enable high-speed file transfers.
• Cross-Platform: Works on any device with a modern web browser.
• Simple UI: Intuitive interface for creating and joining transfer sessions.

Architecture

QuickDrop consists of two main components:

1. Client: A React-based web application for users to create and join file transfer sessions.
2. Server: A Node.js server that facilitates WebRTC signaling and session management using Socket.io and Redis.
