Tornado

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. It is designed for building scalable, non-blocking web applications and services, particularly suited for handling long-lived connections like WebSockets. It uses an event-driven, non-blocking I/O model to support thousands of simultaneous connections efficiently.

Also known as: Tornado Web Server, Tornado Framework, Python Tornado, TornadoIO, Tornado (Python)

Why learn Tornado?

Developers should learn Tornado when building real-time web applications, such as chat apps, live dashboards, or APIs requiring high concurrency, due to its asynchronous capabilities. It is ideal for use cases where performance under heavy load is critical, such as in microservices or IoT applications, as it avoids the overhead of threading by using coroutines and callbacks.
