CherryPy vs Flask: Which is better?

Flask is a web framework written in Python for developing online applications. It is built on the Werkzeug and Jinja 2 frameworks. It’s a simple framework with no batteries included. Yet, by adding essential functionality as needed, it may be expanded to serve complicated applications and use cases. It adheres to the principle that if anything needs to be initialised, the developer should do it.

CherryPy may be used to build web apps in the same way which every other object-oriented Python programme can. CherryPy has sessions, static files, cookies, file uploads, cache, decoding, verification, compressing, and many other features.

Let’s analyse how Flask and CherryPy stack up against one other in terms of numerous factors and features, and which one to use when.

What is Flask?

Flask is a Python micro-framework which can be used to create web apps. This open-source architecture is accessible with the most popular operating systems, including Windows, Mac OS X, and Linux. This basic framework, which is based on Werkzeug and Jinja 2, allows for a lot of expansion. While developing sophisticated applications, you may also incorporate any and all required capabilities to it. By collecting libraries and modules while keeping the heart of your project simple and scalable, this design aids you in developing an excellent online app.

It not only gives you a variety of tools and utilities for quick construction, but it also allows you to choose your own database, template engines, and servers. You don’t have to create code for thread management or protocols if you use Flask. This dependable framework has built-in unit testing and synchronous request processing.

It has various readily customizable layout and data storage conventions. You can use the Flask-Admin extension instead of the built-in admin interface. It works with SQLAlchemy, MongoEngine, Peewee, and other backends. This architecture’s main elements are simple to grasp. You can get help from one of the many internet services available.

What is CherryPy?

CherryPy is a Python framework that may be used to create any type of object-oriented web application. This dependable open-source architecture is compatible with all major operating systems, including Windows, Mac OS X, and Linux. Encoding, caching, cookies, sessions, static files, authorisation, compression, and other features are available in the CherryPy framework.

CherryPy is an extendable framework that makes it simple to use all of Python’s libraries and features. When the software built using this design needs to accommodate more users, it may be scaled up. You can also host your apps on its HTTP server. The syntax of this design is relatively simple. As a result, understanding and using CherryPy isn’t difficult at all. The dynamic core of this server structure assists app development speed and efficiency. Data abstraction is used by its independent components to reduce complexity.

Differences between CherryPy and Flask

Here are some of the key differences between CherryPy and Flask which will help you differentiate between the two-

Databases Supported 

Flask lacks an in-built ORM framework, open-source libraries and extensions such as Flask-SQLAlchemy and Flask-Pony can be used. This architecture is perfect for NoSQL database development. MongoDB, CouchDB, Cassandra, and DynamoDB are examples of open source tools or extensions that enable NoSQL databases.

Alternatively, you may employ Python modules and extensions to maintain relational databases with CherryPy. You have the freedom to choose your preferred extension because there is no built-in ORM framework.

Web Templates

Templates are static data files that can also serve as stand ins for data streams. Flask can render templates to acquire the final document with the help of the templating engine Jinga. (Web Server Gateway Interface (WSGI) applications can receive forwarded requests from web servers.) HTML enables WSGI web applications.

There is no HTML templating engine in CherryPy. However, famous ones like Mako, Jinja2, and Cheetah can be readily integrated into the framework. It also supports WSGI, so you can turn your web service into a WSGI application.

Third Party Libraries 

Flask comes with a slew of third-party libraries and tools. Through easy integration, you can incorporate them into your project’s typical tasks. Furthermore, Flask has a well-developed and diverse community that provides quick and effective resolutions if a problem arises.

CherryPy is a scalable and flexible Python framework that makes integrating with any conventional Python module a breeze. However, this architecture’s relatively small community does not provide any focused solutions or resources. The lack of solutions often concerns the developers who utilise this minimalistic and lightweight framework because it only gives a few essential functionalities.

Security of Applications 

Flask comes with strong anti-cross-site scripting and anti-JSON security features. To safeguard your data against Cross-Site Request Forgery, you must set up Content Security Policy (CSP) as your response header (CSRF.)

The CherryPy governance framework includes a variety of tools for testing and debugging your application. It also contains built-in capabilities that assist you with operations such as code encoding, cache, sessions, and user authorization, as well as sessions and caching.

Popularity 

Flask is a well-known web framework for Python programmers. On GitHub, it has roughly 54.5K stars and 635 active contributors. Flask is a prerequisite for some Python programmers, hence it has a more competitive employment market

In contrast, although being considerably older, CherryPy is less well-known among programmers. On GitHub, it has only 1.4K stars and 109 collaborators. Flask is the clear victor in terms of popularity.

The correct Python platform streamlines the problem-solving procedure. You can put your doubts to rest now that you recognize when to use Flask and CherryPy. You can also compare and contrast different Python frameworks. It enables you to make the best use of them in order to achieve your web development goals.
