Iii Realtime Streams

A WebSocket-based realtime streaming system that sits somewhere between Socket.io's simplicity and Firebase's managed infrastructure. You get CRUD operations for stream items, pub/sub messaging to groups of connected clients, and support for custom adapters if the default backend doesn't fit. The key primitive is organizing streams by name and group ID, so you can push events to specific segments without broadcasting to everyone. Worth checking out if you need live updates but want more control than a hosted service gives you. 17.5K stars suggests the broader iii project has decent traction, and it runs on port 3112 by default if that matters for your setup.
