A Python library providing a simple async broadcast/publish-subscribe API over multiple backends including Redis PUB/SUB, Redis Streams, Kafka, Postgres LISTEN/NOTIFY, and an in-memory backend. It is commonly used to add realtime streaming to async web apps, such as WebSocket chat applications.

Use cases

• add realtime pub/sub messaging to an async python web app
• broadcast websocket chat messages across multiple server instances
• subscribe and publish to redis pub/sub from asyncio
• use postgres listen/notify for event broadcasting
• stream events to connected clients via websockets
• swap messaging backends behind a single broadcast API

When to choose

• you need a simple unified pub/sub abstraction over Redis, Kafka, or Postgres in an async Python app
• you are building realtime features with Starlette/FastAPI websockets
• you want an in-memory backend for local development and testing

When to avoid

• you need full-featured message queue semantics like acknowledgments, retries, or dead-letter queues
• you are not using an async Python stack
• you need guaranteed message delivery or persistence beyond what Redis Streams offers
