Top 10 Python Frameworks for Web Development in 2025

Python is a favorite programming language among developers worldwide. It is fast, reliable, and efficient. Many multinational corporations use Python for web development. Python developers use individual components that are readymade to reduce time-to-market. 

Python does not possess built-in features for fast customized web application development. For this, developers choose Python’s vast collection of libraries. However, there are Python frameworks for mobile app development as well. In this blog, we attempt to list the top 10 Python frameworks for web app development that a company should take heed of. 

Python Frameworks for Web App Development

1: Django 

It is an open-source Python framework that is free to use and enables developers to create complex code and apps easily and quickly. It is possible to build high-quality web applications using Django.

Django is the most popular among Python frameworks for app development and can be used to quickly develop APIs and web applications. This framework is popular because of its many libraries, fewer lines of code, and the ability to reuse components.

Django – Key Features

• You can define patterns for the URLs in your app
• There is a built-in authentication system
• Powerful URL system
• OO programming language database for best data storage and recovery
• Automatic admin interface for editing, adding, and deleting during customization
• Caching framework with multiple cache mechanisms

2: CherryPy 

This one is a fast, stable, yet minimalistic framework for developing web applications in Python. It is open-source and runs on any working framework that supports Python.

You can use any technology for data access and template formation when using CherryPy. It has the capability of a web framework and can be used to create sessions, static, file uploads, cookies, etc.

CherryPy allows web app development in a manner similar to the development of an OO Python program. This results in the development of source code in less time.

CherryPy – Features

• A configuration system that can be used by developers and deployers
• Flexible Plugin system
• Profiling, testing and in-built coverage support
• Tools for encoding, caching, authentication, sessions, static content, etc.
• An HTTP/1.1-compliant and WSGI thread-pooled webserver
• Runs on Python versions 2.7+, 3.5+, Jython, PyPy, and Android

3: Pyramid

It is an open-source Pyramid web development framework and is used by many tech giants like Dropbox and Yelp. The framework is popular because it is flexible and lightweight and can be used to build complex projects and essential web apps. Pyramid runs on Python 3.

Pyramid - Features

• Supports Python 3.8 and 3.9.
• Helps large and small apps to run well
• New security APIs to support a massive overhaul of the authentication and authorisation system.
• HTML structure validation as well as generation
• Testing, support, comprehensive data documentation
• Flexible authentication and approval

4: Grok

Grok's open-source web framework is based on the Zope toolkit (ZPK) technology and works to speed up app development. It provides an agile development experience to 

developers by advocating two principles:

• Convention over configuration
• DRY (Don’t Repeat Yourself)

Developers refer to network/independent libraries as required by tasks in Grok. Grok’s UI is similar to other full-stack Python frameworks such as TurboGears and Pylons.

Grok – Features

Helps to develop robust, extensible web applications for business needs

Allows web developers to use the power of Zope 3

Robust object database for storage

Integrated data security for applications to grant access to specific users

5: TurboGears

This Python web application framework has been designed to overcome inadequacies of commonly used web/mobile app development frameworks. TurboGears 2, is built atop other web frameworks, such as TurboGears 1, Rails, and Django.

TurboGears - Features

• This web application framework is used for solving complex industry-oriented problems
• A transaction manager helps with multi-database deployments
• TurboGears officially supports MongoDB as a primary storage backend.
• It supports multiple template engines

6: Web2Py

This framework is written using Python and is free and open source. It is suited for the agile development of secure database-driven web apps. It is a full-stack framework.

Web2Py - Features

• It guides a web developer to follow best practices in software engineering (using the MVC pattern)  
• Automatically addresses issues leading to security vulnerabilities 
• Includes a Database Abstraction Layer (DAL) to write SQL dynamically

7: Flask

This Python web framework is popularly used for developing complex web apps. Though this framework offers suggestions, it does not enforce any dependencies/project layout.

Flask - Features

• It is flexible.
• The framework keeps the core simple yet extensible
• Flask has many hooks used to customize its behavior

8: Bottle

Bottle is a lightweight, fast, and simple WSGI micro-web framework used for building Python web applications. It depends only on the standard Python library. 

Bottle - Features

• This framework runs with Python versions 2.7 and 3.6+
• Its fast and Pythonic built-in template engine supports Jinja2, Mako, and Cheetah templates
• It provides easy access to headers, file uploads, form data, cookies, and other HTTP-related metadata.
• It has in-built HTTP development server and supports Bjoern, Google App Engine, fapws3, CherryPy, or other WSGI-capable HTTP servers

9: Tornado

With a non-blocking framework I/O, Tornado is a Python web framework and also an offbeat framework library. The framework is designed in such a manner that when configured correctly, it can handle over 10000 simultaneous connections. Thus it is an important tool for building apps with large numbers of simultaneous clients. 

Tornado – Features

• Allows use of 3rd-party authentication and authorization 
• Superior quality, non-blocking HTTP customers, and real-time services
• High-quality output
• Interpretation and localization support
• Web templates and user authentication support

10. BlueBream

BlueBream is an open-source Python web application framework, server, and also library for website developers. Developed by the Zope team, it was formerly called Zope 3. It best performs from medium to substantial activities and helps to apportion into different re-usable segments.

BlueBream – Features

• Emphasizing Python WSGI compatibility
• Availability of unit and functional testing capabilities
• Works as the primary mechanism for plugged security approaches
• XHTML-compliant language for templates creation
• Automatic form generator tool
• Ability to develop strong reusable components

Testing Python Websites on Real Devices

Compared to emulators, testing Python websites on actual hardware offers a more realistic representation of user interactions and experiences. This is the reason why:

• Authentic Environment: Real devices show compatibility and performance concerns that are true to life by supplying the hardware, software, and network situations that users actually encounter.

 

• Precise Interaction Testing: Emulators are unable to accurately replicate the subtleties of touch, gesture, and mobile sensor interactions, which might impact a website's usability and functioning.

 

• Diverse Conditions: By testing your website on actual hardware, you can assess its performance in a range of real-world scenarios, such as varying network speeds and concurrent app activity.

 

• Reliability: Authentic device testing guarantees that your website functions properly for every user, on any device, lowering the possibility of unpleasant surprises after launch.
• Performance Discrepancies: Emulators might not fully capture a website's real-world performance on real hardware, especially when it comes to memory utilisation and processing speed.
