Snapdrop
Snapdrop is a web-based local file sharing tool and progressive web app designed for transferring files between devices on the same local network. It functions as an end-to-end encrypted transfer tool that allows users to move data across different devices and operating systems without manual configuration.
The service supports self-hosting through a containerized deployment model, allowing users to run private instances of the file sharing service on their own infrastructure. This ensures that data transfers remain within a private local network.
The system uses a signaling server for local network discovery and coordinates peer-to-peer connectivity to establish direct data channels between browsers. Security is maintained through client-side encryption to protect files during transmission.
Features
- WebRTC Transfer Tools - Establishes direct browser-to-browser data channels for serverless file transfers using WebRTC protocols.
- Cross-Device Asset Migration - Facilitates the rapid transfer of files between different hardware platforms, such as phones and computers, without cloud intermediaries.
- File Sharing - Enables the distributed transfer of digital files directly between devices on the same local network.
- Local Network Discovery - Identifies active sessions on the same subnet by tracking client connection IPs via a signaling server.
- Signaling Servers - Implements a central signaling server to exchange connection metadata between devices before establishing peer-to-peer links.
- Web-Based Local Sharing Tools - Offers a browser-based tool for discovering and transferring files to other devices on the same local network.
- End-to-End Encryption - Ensures data remains encrypted during transmission so that only the communicating devices can access the files.
- Containerized Deployments - Provides a containerized image of the signaling infrastructure for consistent hosting on private server environments.
- Private Infrastructure Hosting - Supports deploying the service on private infrastructure to ensure data sovereignty and local network containment.
- Private Networks - Enables the exchange of encrypted data between trusted devices within an isolated local network environment.
- Client-Side Encryption - Secures file data using cryptographic keys generated directly in the browser to ensure privacy during transmission.
- Progressive Web Apps - Functions as a progressive web app that provides a native-like experience across various devices and operating systems.
- Self-Hosted File Servers - Allows running a private file sharing instance on personal infrastructure to keep data transfers within a local network.
- File Sharing Tools - Local file sharing via web browser.
- Collaboration And Storage - Browser-based local file transfer utility.
- File Management - Local file sharing via web browser.
