Architecture

How It Works_

100% Peer-to-Peer. Zero Data Storage.

1. The Stack

Built for Speed & Reliability

PasteX is built on a modern hybrid architecture designed to be incredibly fast while respecting your privacy:

  • UI Next.js 15 (React)
  • CSS TailwindCSS (Neo-Brutalism)
  • SIGNALING Socket.io (Node.js)
  • DATA WebRTC (RTCDataChannel)
2. WebRTC Peer-to-Peer

Direct Browser Connection

Unlike traditional file sharing apps (like Google Drive or WeTransfer), PasteX never uploads your files to a server.

Step A: When you join a room, our Socket.io server introduces your browser to the other person's browser (Signaling).

Step B: Your browsers negotiate a direct connection using WebRTC.

Step C: Once connected, files are broken into chunks and streamed directly between the devices.

3. Privacy by Design

No Trace Left Behind

PasteX rooms are completely ephemeral.

  • No databases are connected to this application.
  • No files are ever stored on a server disk.
  • Once all peers leave a room, the shared text buffer is instantly destroyed.
