Collab — Real-time Collaboration Tool (Backend)

Backend powering real-time document sync across multiple connected clients.

How it works

• Django Channels manages WebSocket connections per document session
• Redis pub/sub broadcasts changes to all connected clients in real-time
• PostgreSQL stores document state and user sessions
• Each keystroke is an event — published, distributed, and rendered across all clients with no polling
