Tornado is an asynchronous Python web framework and asynchronous network library, designed for handling long-lived connections and real-time web services. Developed by Facebook, it's widely used for building scalable applications with non-blocking I/O.

Key Features 📋

  • Asynchronous Networking: Built on async/await for non-blocking request handling
  • WebSocket Support: Real-time bidirectional communication with clients
  • Single-Threaded Performance: Efficient event loop for handling thousands of concurrent connections
  • Lightweight Design: Minimal overhead with modular architecture
  • Rich Ecosystem: Integrates with PyOpenSSL, MongoDB, and OAuth2 out of the box
  • Web Server & Application: Combines both server and app components in one package

Use Cases 🚀

  • Chat applications 💬
  • Live data dashboards 📊
  • APIs with long polling 📶
  • IoT device communication 🌐
