Nebula

Nebula is a tool for sending files to nearby devices within the same network.

"Why?"

Honestly... I was just curious how this kind of thing works.

How it works

1. Discovery

Nebula uses UDP Multicast to discover other devices running Nebula on the same network.

2. Interface

Navigate to http://localhost:35436/page and you will see a beautiful interface listing discovered devices, with a button to send them a file.

3. File transfer

The file is sent via raw TCP.

Disclaimer

Nebula is just an educational experiment.

This program is not safe since it lacks cryptography, use it on trusted networks.
