FileSpread is a browser-first peer-to-peer file sharing web app. It enables direct device-to-device file, link, and text transfer using WebRTC, without sending shared content through a cloud storage service.
FileSpread is designed for fast, private local sharing across devices on the same network or grid. It uses a lightweight signaling server only for discovery and WebRTC connection setup. After peers connect, file and message traffic flows directly between browsers.
