Abstract
Floe is an open-source Cybersecurity & Ethical Hacking project. Encrypted P2P file transfer in the browser, on the desktop, and in the CLI. No accounts, no uploads, no file storage. Floe is an open-source peer-to-peer file transfer application built on WebRTC. Files stream directly between devices; the signaling server negotiates connections and never stores, inspects, or decrypts file data. It is built using JavaScript, Next.js, Socket.IO, TypeScript, React. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.
1. Introduction
Floe is an open-source peer-to-peer file transfer application built on WebRTC. Files stream directly between devices; the signaling server negotiates connections and never stores, inspects, or decrypts file data. When a direct path is blocked, an optional TURN relay bridges the transfer while the data stays end-to-end encrypted. The desktop app and the CLI contain no analytics or telemetry; the only things either sends are an optional, anonymous byte count that powers the public counter and an optional update check against GitHub (once a day in the desktop app, and only when you run floe version in the CLI), and you can turn both off in either. The floe.one website itself runs cookieless, aggregate analytics (including anonymous transfer outcomes) and error monitoring, detailed in the security and privacy docs.
Three clients share one wire protocol: the web app at floe.one, a Windows desktop app, and a Go CLI. Send from a browser tab and receive in the desktop app or the CLI, or any other combination, even across different networks.
Floe for Windows 10 and 11 (x64), currently in beta. The Microsoft Store build is signed by Microsoft and updates automatically.
2. Objective
Encrypted P2P file transfer in the browser, on the desktop, and in the CLI. No accounts, no uploads, no file storage.
This project demonstrates how JavaScript, Next.js, Socket.IO can be applied to a real-world Cybersecurity & Ethical Hacking problem.
