Python Developers: Should You Use Flask or CherryPy?

It is a common question among those studying Python as to which web framework is most popular and which to focus on. For those looking to learn Python, it is important to consider both CherryPy and Flask. CherryPy is a Python-based, web development framework and is often used for creating web applications. On the other hand, Flask is a microframework, which is known for its ease of use and flexibility. In terms of popularity, Flask has become increasingly popular in recent years. As such, those studying Python in 2022 should certainly consider learning Flask. However, CherryPy still has its place in web development and is worth considering. Ultimately, it is up to the individual to decide which framework they would like to focus on.

Hopefully, you’ll find the answers to all of these questions in this blog article. Okay, so let’s begin.

Python is one of the most popular and widely used programming languages today, offering a range of web frameworks to developers. These web frameworks, which are made up of modules and packages, enable developers to create websites, online applications, and web services. Python web frameworks are typically divided into two categories: full stack and partial stack. Full stack frameworks provide a comprehensive set of components and tools for developing web applications, while partial stack frameworks offer a more limited set of features.

Full-stack frameworks provide a comprehensive approach to application development, including features such as form validation, template layouts, and form generators. Python offers many popular full-stack frameworks, including Django, Turbogears, web2py, Cubicweb, Giotto, Grok, and Pylons. These frameworks are widely used and appreciated for their ease of use and powerful capabilities.

Non-full-stack frameworks, in contrast to full-stack frameworks, enable the creation of lightweight applications that utilise specific components from the Python standard library. Popular non-full stack frameworks for Python include CherryPy, Flask, Hug, Pyramid, Albatross, Falcon, and many more.

Explain CherryPy to me.

CherryPy is a powerful, object-oriented Python framework that enables developers to rapidly create stable and high-performance web applications. As one of the oldest Python frameworks, it offers a range of features which allow developers to quickly build robust, database-backed applications with minimal coding. With CherryPy, developers can easily create, retrieve, update and delete functions for their applications.

Flask is what?

Flask is a lightweight Python framework that provides developers with the fundamental components necessary for web development, such as routing and requests. Flask provides guidance, but leaves the structure of the project and the choice of dependencies to the discretion of the software engineer. In addition, the WSGI toolkit and Jinja2 template engine are included in this framework, giving developers further resources for their tasks.

A comparison between Flask and CherryPy may be broken down like this:

  1. What’s the Difference Between Flask and CherryPy When It Comes to Application Security?

    CherryPy is equipped with a range of built-in features for user authentication, encryption, caching, and other security solutions. Furthermore, the framework offers a selection of helpful tools for analysis and debugging of applications.

    On the other hand, developers may incorporate a variety of security measures into their Flask applications, including hashed passwords, token-based authentication, cross-site scripting, and JSON encoding. It is essential for developers to establish an effective content security strategy in order to ensure the security of application data when using Flask.
  2. Flask vs. CherryPy: A Templating Engine Showdown

    Jinja, the templating engine used in conjunction with Flask, provides developers with the capability to seamlessly create both static and dynamic templates. Furthermore, Flask’s Web Server Gateway Interface (WSGI) toolkit enables developers to take advantage of the server-requested templates when constructing the final document.

    Despite the fact that the Flask framework includes a templating engine, CherryPy does not. Developers have the option to incorporate various templates such as Cheetah, Jinja2, and Mako into the framework for added convenience.
  3. Libraries and community support in Flask vs. CherryPy

    There are a variety of third-party tools and libraries that can be used in combination with the Flask web framework. This is due to the extensive and active community of developers that support Flask, allowing programmers to access reliable answers to their questions and solutions to any bugs they may encounter.

    CherryPy is an alternative framework that can be easily integrated with other Python components and can scale together with your growing needs. Unfortunately, CherryPy does not have an extensive community support, thus developers will need to find their own solutions to any issues they may encounter.
  4. Which is better for database support, Flask or CherryPy?

    Flask applications can employ various databases by making use of database adapters. Open-source libraries such as Flask-Pony and Flask-SQLAlchemy can be employed to achieve object-relational mapping and database support, respectively. These libraries enable developers to integrate popular open-source databases, including MongoDB, CouchDB, Cassandra, and DynamoDB into their Flask applications.

    Additionally, CherryPy lacks built-in relational database management system (RDBMS) or native Structured Query Language (SQL) capabilities. Consequently, developers who wish to benefit from the numerous database plugins and extensions available must incorporate SQLAlchemy.
  5. Comparison of Flask and CherryPy

    Flask supports the use of Python’s unit testing framework for unit testing, which enables developers to evaluate individual sections of code to measure their performance in isolation. Unit testing is an essential tool for ensuring that code works as expected and helps to identify any potential issues early on in the development process.

    CherryPy lacks Flask’s in-built unit testing capability. Modules like Nose and Webtest are used by developers for unit testing.

What makes CherryPy special, and how it’s best put to use

CherryPy offers a multitude of advantages, such as extensibility, scalability, and a straightforward syntax. Additionally, its HTTP server enables application hosting, while its data abstraction allows for easy deployment on WSGI-compliant gateways. These features make CherryPy a highly desirable tool for web development.

CherryPy is an ideal choice for developing lightweight web applications, mobile applications, and RESTful APIs, thanks to its in-built features and user-friendly interface. It does not require a substantial amount of additional resources such as documentation, resources, and templates to use this framework, making it an easy and efficient option for developers.

Flask’s standout qualities and wide range of applications

Flask’s traditional data storage, robust routing architecture, and synchronous request processing are just a few of its standout qualities.

Start-ups can benefit from the advantages of Flask, such as its high scalability, simple web API, and the ability to construct large-scale applications. Furthermore, Flask is an excellent choice for rapidly building working prototypes of a project.


CherryPy is a Python-based web framework which enables the speedy development of clean and maintainable online applications. It is a lightweight framework that facilitates the efficient creation of sophisticated web-based projects. In contrast, Flask is a microframework which utilises multiple Python modules and libraries to build comprehensive, feature-rich online applications.

As Python developers, we must carefully evaluate the pros and cons of CherryPy and Flask, as each framework offers unique advantages and is best suited to specific types of projects. It is essential that we carefully consider all the implications of the CherryPy versus Flask debate in order to make the most informed decision and choose the framework that best meets our needs.

To what extent does CherryPy act as a web server is debatable.

Web application development is made simpler with the implementation of CherryPy, a web framework that provides users with a generic HTTP server and a range of production-ready components that are both high-speed and organised into thread pools. This allows for a more efficient and effective development process.

How about the Flask framework; does it function on the front end or the back end?

Flask is a back-end framework that gives programmers flexibility when it comes to selecting the right tools, libraries, and extensions.

What’s the verdict? Flask versus Django?

Flask is superior for lightweight projects, but Django shines in enterprise-level software.
