Here are some of the famous Python WebSocket Utilities Libraries. Some use cases of Python WebSocket Utilities Libraries include Real-time Chat and Messaging Applications, Online Gaming, IoT Applications, and Real-time Data Visualization and Dashboards.


Python WebSocket utilities libraries are collections of code that provide a set of utilities to help developers create and manage WebSocket connections in Python. These libraries typically provide methods to simplify WebSocket connection setup, message sending, message receiving and connection management. They can also provide additional features such as authentication and SSL/TLS support.


Let us have a look at some of these libraries in detail below.

tornado

  • Can handle up to 10,000 simultaneous open connections, making it ideal for applications with high levels of concurrent users.
  • Can handle multiple requests simultaneously without blocking requests.
  • One of the few web frameworks that supports WebSocket connections.
