Python is no doubt one of the topmost adaptable languages for web development in 2021. Python is used in many cases like web development, mobile app development, data analysis, machine learning, and many more. Based on a recent survey, it is found that Python is one of the widely used programming languages, covering around 50% of the total percentage of languages for programming. Python abbreviated with most versatile frameworks.

Importance of Frameworks

Frameworks are the set of libraries that are used to build high-end applications.

Frameworks are like a backbone for any programming language. It is used to inspect the overall functionality of code, check the bugs or errors, check the code reusability, user intent codes, and manage the hardware and software. Frameworks are known to make the job of web developers effortless by reducing the development time and cost.

There are many Python frameworks and each has its unique features. To decide which framework to use for which project, is like a crooked task.


So, we have below compiled for you a list of the Top 10 Frameworks of Python for Web Development in 2021. Let's understand each one of them and start to build your awesome projects. Let's get started.

Distribution of Frameworks

The top of the Python frameworks is divided into three main segments.

  • Full Stack: A full-stack framework cohesively works with a pack of libraries, embedded plugins, and extensions. These frameworks are supported by the front-end and back-end interfaces and databases. They have MVC architecture that is capable of creating heavy web applications. Other features are template layouts, form validation, and generator, and many more.
  • Micro Framework: These are not full-fledged frameworks, they use only essential features of an application. It excludes some features like database abstraction, input validation, web template engine, and an authentication function. It supports only manual coding.
  • Asynchronous: Asynchronous frameworks are developed to handle large concurrent tasks and connections. They contain an async IO library of Python. In this framework, tasks can run separately and not depend on any other tasks for their completion.


Based on the above classification, all of the top frameworks of Python are categorized. Let's understand them one by one.

1. Django

Whenever the name of top Python Frameworks comes, Django is the first one to look at. It is one of the widely used frameworks for web development by full-stack developers. It covers about 14% of the total framework percentage of Python.


It is a full-pack stack of frameworks that consists of features like database schema migration, object-oriented mapping, URL routing, template engine, authentication support, and libraries.

It supports third-party templates and is one of the best frameworks for prototyping.


Some important features of Bottle include HTTP server requests, other plugins, and database support. It provides dispatching of routes and URL parameter support.

5. Falcon

Falcon is one of the Micro Frameworks intended to build web applications and APIs. Falcon facilities are less dependent on other third-party support and extensions. Developers can smoothly use the code, handle HTTP and REST APIs. REST API consists of URL templates for spontaneous routing, which is inspired by resource classes.

Falcon is one of the powerful frameworks that help developers with an extra boost and Cython (C- extension for Python) support. It provides parallel functionality with the same hardware support to handle all requests on the server. There is no misplacement of codes makes it 100% code secured and gives the flexibility to developers to write a high-quality codebase.


Many big tech players like LinkedIn, RackSpace, and OpenStack used Falcon. Some of its top features are Dry (don't repeat yourself) requests processing, HTTP error handling, feasible solutions to handle headers and bodies with request and response classes, and likewise. Falcon is capable of handling front exceptions and performing intuitive testing support using WSGI helpers and mocks.
