Snapdrop

Snapdrop is a browser-based peer-to-peer file sharing tool that transfers files directly between devices on the same local network without uploading to any intermediate server. It operates as a progressive web app, meaning it works across devices without installation, and uses end-to-end encryption to ensure only the sender and receiver can read the content being transferred.

The application establishes direct browser-to-browser connections using WebRTC, splitting large files into chunks for real-time streaming with progress tracking. It discovers nearby devices on the same subnet through local network discovery, and caches application assets via service workers for offline-capable functionality. The entire transfer model is serverless, with zero persistence on any server, ensuring privacy and minimal infrastructure.

Snapdrop supports sending and receiving individual files or entire folder structures while preserving directory hierarchy, with the ability to accept or ignore each incoming transfer. For users who want full control over their hosting and privacy, the application can be deployed as a private instance using a Docker container that packages the signaling server and static assets.

    Sharedrop is a browser-based file drop application for transferring files directly between devices without requiring software installation or account registration. It uses WebRTC to establish peer-to-peer data channels, allowing files to be exchanged between different operating systems without routing traffic through a central server. The project provides mechanisms for both local and remote connectivity. It identifies active users sharing the same public IP address for immediate local device discovery and allows the creation of private sharing rooms via unique session links for users on diff

    Filepizza is a web-based peer-to-peer file sharing application that enables direct browser-to-browser data exchange. It utilizes WebRTC to establish connections between devices, allowing files to be sent without uploading data to a central server. The project provides a password-protected file sharing mechanism that secures transmissions via symmetric-key stream encryption. It includes a containerized signaling server that can be self-hosted to coordinate connections between peers and facilitate NAT traversal across restrictive networks and firewalls. The application supports multi-file tran

    Opendrop is a Python implementation of the AirDrop protocol used for transferring files and links between devices over wireless connections. It functions as a peer-to-peer wireless file transfer system and a tool for automating the exchange of network passwords using specialized handshake mechanisms. The project enables the discovery of nearby hardware by scanning for Bluetooth Low Energy advertisement packets and searching local subnets for specific service signatures. It establishes direct communication links through monitor mode and raw frame injection to move data without requiring a stan
