MultiStream uses Gun.js for decentralized, real-time data sync:

• No server/database required
• Data syncs via public relay servers
• Works on any static hosting (GitHub Pages, Netlify, etc.)
• Room state persists even when host disconnects

• Chrome/Edge (recommended)
• Firefox
• Safari
• Mobile browsers

• Gun.js - Decentralized database (loaded via CDN)
• Windy.com - Weather radar embeds

• No data stored on your server
• Room data stored on Gun.js relay network
• Chat messages expire after 2 hours
• No analytics or tracking

For better reliability, you can run your own Gun relay:

npm install gun
npx gun

Then update the Gun initialization in the HTML:

const gun = Gun(['https://your-relay-server.com/gun']);
