Well, since Django‘s first appearance, it becomes one of the best python web framework. Django comes with almost every battery you may need, making it more suitable for building big applications than small ones.

For many years Django was steady at version 1.x. In 2017, with version 2.0 it dropped compatibility with Python 2 in favor of Python 3.4 and up. Django 3.0, released in December 2019, requires Python 3.6 or better and adds support for the new asynchronous ASGI standard for Python web applications.

A major part of Django’s popularity is deployment speed. Because Django includes so many pieces you need for developing the average web application, you can get moving quickly. Routing, URL parsing, database connectivity including an ORM (object-relational mapper), form validation, attack protection, and templating are all built-in.

Django offers some amazing features:

  • Excellent Documentation
  • SEO Optimised
  • High Scalability
  • Versatile in Nature
  • Offers High Security
  • Thoroughly Tested
  • Provides Rapid Development

Flask is a Python framework available under the BSD license. It was inspired by the Sinatra Ruby framework. Flask depends on the Werkzeug WSGI toolkit and Jinja2 template.

The main idea behind Flask is to help build a solid web application foundation. From there, you can use any extensions you might need.  Flask is chosen for any and all projects. In fact, it’s a default choice for any web project that isn’t a match for Django. Flask’s lightweight and modular design make it easily adaptable to developers’ needs.

Furthermore, it has a number of useful features, such as an integrated development server and a quick debugger, Jinja2 template engine, support for secure cookies, the ability to connect any ORM. In addition, Flask allows the developers to build a solid web application foundation from where it is possible to use any kind of extensions required. The micro-framework is compatible with Google App Engine.


  • Built-in development server and a fast debugger
  • Integrated support for unit testing
  • RESTful request dispatching
  • Jinja2 templating
  • Secure cookies support (client-side sessions)
  • WSGI 1.0 compliance
  • Unicode-based
  • Ability to plug in any ORM
  • HTTP request handling

Tornado is another micro framework aimed at a specific use case: asynchronous networking applications. Tornado is well-suited for creating services that open a great many network connections and keep them alive that is, anything involving WebSockets or long polling. Moreover, It requires Python 3.5 or higher and drops Python 2 support entirely.

Like Bottle or Falcon, Tornado omits features extraneous to its central purpose. Tornado has a built-in templating system for generating HTML and other output and provides mechanisms for internationalization, form handling, cookie setting, user authentication, and CSRF protection.

Furthermore, Tornado excels at providing infrastructure to apps that need close control over asynchronous networking. For instance, Tornado provides not only a built-in asynchronous HTTP server but also an asynchronous HTTP client. Thus, Tornado is a good choice for building apps, such as a web scraper or a bot, that query other sites in parallel and act on the returned data.

As the name suggests, FastAPI is built to create API endpoints quickly, and it runs fast too. It makes use of the Starlette project for its high-speed networking core, but you don’t need to know about Starlette’s internals to use FastAPI. You define endpoints in much the same manner as a Flask or Bottle app—use decorators to indicate which functions handle which routes—and then return dictionaries that are translated automatically into JSON.

You can easily override how things are returned. For instance, if you want to return HTML/XML from some endpoints, you can do that by simply returning a custom Response object. If you want to add custom middleware, you can pop in anything that follows the ASGI standard.

Developers can develop the Python backend framework any way they need, however, it was designed for applications that are open-ended. Besides, Flask has been used by big companies, which include LinkedIn and Pinterest. Compared to Django, Flask is best suited for small and easy projects. Thus, you can expect web server development, support for Google App Engine as well as in-built unit testing.


  • Increase in development speed by 200% to 300%
  • Reduced errors by 40%
  • Less time debugging
  • Minimization of code duplication
  • Automatic interactive documentation

Asynchronous framework AIOHTTP is a Python framework that relies heavily on Python 3.5+ features, such as async & awaits. it makes use of Python’s asyncio library and is thus an asynchronous framework. In addition to being a server web framework, AIOHTTP can also serve as a client framework. Also, It provides a request object and router to enable the redirection of queries to functions developed to handle the same. Besides, the aiohttp package also supports Server WebSockets and Client WebSockets.


  • Supports both client and server-side of the HTTP protocol.
  • Supports both client and server Web-Sockets out-of-the-box and avoids Callback Hell.
  • Provides Web-server with middlewares and pluggable routing.
Django Rest

Official Website |GitHub |PyPI

Django REST framework is a powerful and flexible toolkit for building Web APIs. Besides, It is a flexible and fully-featured toolkit with modular and customizable architecture that makes possible the development of both simple, turn-key API endpoints and complicated REST constructs. In addition, it contains a wide set of out-of-the-box features. Also, the core view class is very simple and the framework, in general, is easy to use.

Furthermore, the main idea behind the DRF is to clearly divide a model, the generalized wire representation (e.g. JSON, XML, etc.), and also a set of generic Class-Based-Views that can be customized to satisfy the specific API endpoint using Serializer that describes the mapping between them. Moreover, the Django REST Framework includes a built-in API browser for testing out newly developed API.  Besides, it allows the flexibility to extend and customize the framework’s tools according to the programmer’s demands that greatly reduces development time. The Django REST framework is used by such giants as Mozilla and Eventbrite.


There are Some other frameworks AS FOLLOWING:

So, in this article, The best python web framework to learn in 2021, we have listed down some of the major web frameworks. Each framework has its own importance and features. Although, you must select the right one on the basis of your project need and requirement. As frameworks are the foundation of web development. Choosing one largely depends on the type of app you intend to develop.

Now, if we go with the trends, Django and Flask are the top Python frameworks so far. Among these, Django is the most used. Well, Django and Flask represent two major categories of frameworks: full-stack frameworks and micro frameworks (sometimes called non-full-stack), respectively.

If you need to develop a feature-rich system, it’s best to choose one of the full-stack frameworks. A micro-framework is a good choice for small and mid-sized projects, prototyping, and learning the structure of frameworks.

So, be careful while choosing the framework. Do tell us which one is your pick in the comment section below.
