Why Tornado is a better framework of Python

No Comment Yet

Python has been the go-to language for building responsive web applications and services, right from quick RESTful APIs to full-fledged web applications that serve millions of users. If you have been taking part in this area, you’d have probably used or know about the most popular web frameworks already — Django, Flask, Tornado, and so on.

Check out how Python detects 600+ bug risks, anti-patterns, and security vulnerabilities in Python code. Here’s a comparison of Python’s new web frameworks: Tornado, which you should consider for your next project. These new frameworks have taken a fresh approach focusing on the performance and expressiveness of the API. Take a look into Python Coroutines to get an idea about it; it’s incredible. Tornado offers several ways to build an app that takes advantage of co-routines, including allowing us to set locks on function calls, conditions for synchronizing asynchronous routines, and a system for manually modifying the events that control the I/O loop.


Tornado is considered a powerful open-source web-framework of Python and an asynchronous networking library, ideal for such web app development that serves a higher number of simultaneous users and superior quality. It is highly scalable, simple(in contrast to other callback frameworks), and has clean code, therefore prevalent among Python’s asynchronous libraries. Tornado framework doubles down as a non-blocking web server, offers built-in support for real-time services, user confirmation, Python-based web templating language, non-blocking HTTP customer, and localization. Tornado uses a non-blocking network I/O, efficiently tackling the C10k issue so well. It can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. It offers excellent processing performance, do not rely on multi-process/multi-thread, to a certain extent, to solve the C10K problem.

Who uses Tornado Framework?

According to some reports, 83 Companies use Tornado in their tech stacks, including Facebook, Delivery Hero, HENNGE, etc.

Features of Tornado Web Framework: 

  • Lightweight web framework
  • Asynchronous non-blocking IO processing
  • Excellent load resistance
  • Custom HTML template engine
  • Excellent processing performance does not rely on multi-process/multi-stream.
  • Integrates SSL
  • Ideal for WebSockets.
  • Fast, clear, and easy-to-read documentation
  • Integrates in www/HTTP infrastructure
  • Tornado recommended integration with other frameworks, libraries, and the HTTP server is also possible.
  • A tornado is a great tool that lets us scale our Python-based web content.
  • Custom routing handling – offers generic classes than can be used for route creation,
  • Supports WSGI, but not recommended – the user should use Tornado’s interfaces instead,
  • Outside-the-box WebSockets support, authentication (e.g., via Google), and security features 
  • No additional tools are required for REST API creation.


Interestingly, for a software engineer, the Python tornado is pretty simple and easy to use and lets creators scale web services over Python, which was previously impossible to do in a concurrent manner. Tornado meant for projects benefiting from specified and deliberate I/O control; allows for co-routines and quickly exposes methods, functions, and classes that can define actions and handle how requests are received/responses sent (e.g., DB operations) on application occur. Tornado makes it very simple to get started with minimum viable web apps, reducing Development time, and giving a decent enough result at the end. The amount of support through the community also makes it a desirable choice compared to other python web frameworks.
