## What it is
Autobahn|Python is an open-source library implementing the WebSocket protocol and the Web Application Messaging Protocol (WAMP) for Python 3.11+, running on both Twisted and asyncio. It lets developers build WebSocket and WAMP clients and servers supporting RPC and publish/subscribe messaging.

## Use cases
- build a websocket server in python
- add real-time messaging to a python app
- implement pub/sub over websockets
- call remote procedures from python over wamp
- websocket client library for asyncio
- use websockets with twisted

## When to choose
- you need WebSocket or WAMP support in Python on Twisted or asyncio
- you want RPC and pub/sub messaging patterns over WebSocket
- you need a mature, standards-compliant WebSocket implementation

## When to avoid
- you only need simple HTTP request/response
- you use a framework other than Twisted or asyncio
- you need WAMP in a language without an Autobahn client

## Facets
- artifact type: library
- maturity: active
- function: websocket, rpc, middleware, http-client, http-server
- domain: web-development, networking, apis
- platform: python, cross-platform
- tags: wamp, pubsub, twisted, asyncio, real-time-messaging, real-time
