# DashBeam — Peer-to-Peer Encrypted File Transfer Without the Cloud

> Send files of any size directly between devices with no cloud storage, no accounts, and no restrictions, using QUIC transport and end-to-end encryption.

## Install

Save as a script file and run:

# DashBeam — Peer-to-Peer Encrypted File Transfer Without the Cloud

## Quick Use
```bash
# Desktop: download from dashbeam.app
# CLI:
pip install dashbeam
dashbeam send myfile.zip
# Share the generated code with the receiver
```

## Introduction
DashBeam is an open-source file transfer tool that sends files directly from one device to another without uploading to any cloud server. All transfers are end-to-end encrypted and require no user accounts. It supports desktop, mobile, CLI, and web interfaces.

## What DashBeam Does
- Transfers files peer-to-peer with no cloud intermediary or file size limits
- Encrypts all data end-to-end using TLS 1.3 over the QUIC protocol
- Verifies file integrity with BLAKE3 hashing
- Supports resumable transfers that survive network interruptions
- Works across desktop, mobile, CLI, and web clients

## Architecture Overview
DashBeam uses a relay server for signaling and NAT traversal, but file data flows directly between peers whenever possible. The transport layer is built on QUIC for multiplexed, low-latency streaming. Each transfer session generates a unique code; both sender and receiver derive encryption keys from a shared secret tied to that code. The relay only sees encrypted traffic.

## Self-Hosting & Configuration
- Download the desktop app from dashbeam.app or install CLI via pip
- Optionally self-host a relay server using the provided Docker image
- Configure relay URL in client settings if using a self-hosted relay
- No accounts, registration, or API keys required
- Supports proxy and firewall-friendly fallback through the relay

## Key Features
- Zero-knowledge architecture: relay servers cannot read transferred data
- Cross-platform: Windows, macOS, Linux, iOS, Android, and web
- Resumable transfers with progress tracking
- No file size limits or bandwidth throttling
- Folder transfer with directory structure preservation

## Comparison with Similar Tools
- **croc** — CLI-only P2P transfer; DashBeam adds desktop, mobile, and web clients
- **Magic Wormhole** — Python-based P2P transfer; DashBeam uses QUIC for better performance
- **Send (Firefox Send)** — uploads to a server; DashBeam is direct peer-to-peer
- **LocalSend** — LAN-only transfer; DashBeam works across the internet
- **Tailscale/WireGuard** — VPN tunnels; DashBeam is purpose-built for one-off file sends

## FAQ
**Q: Do both parties need the app installed?**
A: The receiver can use the web interface at dashbeam.app without installing anything. Desktop and mobile apps are available for heavier use.

**Q: Is there a file size limit?**
A: No. DashBeam streams data directly between peers, so transfer size is limited only by disk space.

**Q: What happens if my connection drops mid-transfer?**
A: Transfers are resumable. Reconnect and the transfer picks up where it left off.

**Q: Can I self-host the relay server?**
A: Yes. A Docker image is provided. Point your clients at your relay URL.
