websockets is a Python library for building WebSocket servers and clients, with a focus on correctness, simplicity, robustness, and performance. It provides coroutine-based asyncio, threading, and trio implementations, plus a Sans-I/O layer for embedding in other projects.

Use cases

• build a websocket server in python
• connect to a websocket endpoint from python
• stream real-time messages between client and server
• add bidirectional communication to a python backend
• implement a websocket client with threading
• embed websocket protocol handling in another library

When to choose

• you need a mature, well-tested WebSocket implementation in Python
• you want asyncio-based coroutine APIs for concurrent connections
• you need flexibility across asyncio, trio, or threading
• you want a Sans-I/O layer to integrate WebSocket handling into your own stack

When to avoid

• you only need simple HTTP request/response without WebSockets
• you are building a browser or non-Python client
• you need a full web framework with routing and templating rather than just WebSocket support
