## About ButterShare

Transfers files and entire directories directly from one browser to another using encrypted peer-to-peer WebRTC connections. Data streams in real time straight between machines and writes to disk via browser storage APIs without ever uploading to central cloud storage. The connection handles large media files, raw video footage, and complex folder structures through instant end-to-end encrypted session rooms.

## Who is ButterShare for?

Filmmakers, video editors, 3D artists, and developers who need to move massive payloads between machines. Before this, teams had to wait through multi-hour cloud uploads, pay for recurring storage tiers, or hit file size caps on legacy file transfer platforms.

## How does ButterShare work?

First, drop files or whole folders into the browser window to open a transfer room. Next, send the generated link, QR code, or room code to the recipient. Once connected, the receiving browser streams and writes the incoming files straight to local storage.
