Which
backend
framework
works great
for your
business?

Introduction
Among the other backend frameworks, Node.js and Python are the popular ones for web
app development. It may not be easy for business owners to choose between Node.js
and Python as both these backend frameworks are gaining immense popularity.
To sort out this dilemma of Python vs Node.js for business owners as to whether they
should go with Node.js or Python for their app development, we will compare the Python
vs NodeJS in terms of different parameters like scalability, performance, security, etc. So,
let us head towards a precise comparison between Node.js vs Python so that you can
choose the right framework for your business in 2023.

Introduction of Nodejs
An event-based framework like Node.js adds to the efficiency of your project. Due to its
asynchronous characteristics, Node.js is capable of handling simultaneous requests
without the need to block I/O operations. Hence, top NodeJS development company will
suggest you Node.js so that they can use JavaScript for both server-side and client-side
development.
Node js uses JavaScript as a full stack technology for web application development which
helps build robust gaming apps, social networks, forums, live chats etc where speed
matters the most. It is one of the reasons why businesses looking to launch such apps
hire professional Node.js web development services to work on their project.

Introduction of Python
On the other hand, Python is a comprehensive, premium, and object-oriented language.
Its existence in the market for almost 30 years makes it one of the best backend
frameworks. Also, Python comes with plenty of APIs, ancillary tools, and libraries. Python
helps create efficient business applications.
Python has a huge user community base and supporting platforms which makes it the
perfect programming language for businesses looking to build applications for different
use cases.
Python proves to be useful in web application development which is why it is the
preferred back-end language.

Pros & Cons of Node.js vs Python
After knowing about the Python and Node.js basics, let us explore the pros &
cons of the two frameworks in detail.
Pros of Node.js
● Microservice development flexibility
● Affordable
● Robust Tech Stack
Cons of Node.js
● Callback Hell
● Volatile API
● Not able to process CPU-Based
Activity
Pros of Python
● Flexibility
● Faster Development
● Huge Library
Cons of Python
● Reduced Execution Speed
● Memory Exhaustion
● Incompatible with Mobile App
Development

Microservice development flexibility
If you are planning to develop a microservice model, you need to have numerous executions of
development and components while considering Python vs Node.js. Node.js offers free components
that enable the developers to use different modules parallelly. Using microservice development
makes it simple for businesses to take care of testing & product quality.
Pros of Node.js
Affordable
Node.js support both the front and back end of an app which means you don’t need to hire Nodejs
experts (two different developers) for the app development. It directly saves development costs and
speeds up the NodeJS Web development process keeping the quality of the app intact.

Robust Tech Stack
Node.js helps developers access entire JavaScript resources and stack. Along with JavaScript
resources, Node.js offers support from a huge user community.
App development becomes easy with Node.js using MEAN technical stack wherein you get excellent
front-end, back-end, and database support for efficient development.

Callback Hell
When it comes to Node.js, challenges arise due to nested callback function outcomes in callback hell.
This occurs because Node.js is asynchronous. So, in case of multiple callback events, it reduces the
quality of code and it becomes difficult to resolve and preserve.
Cons of Node.js
Volatile API
It is one of the main cons of Node.js which is a recurrent API switch that gives rise to back-end
incompatibility. Due to this incompatibility in NodeJS web development, the codes get altered and
become more volatile.

Not able to process CPU-Based Activity
Node.js is unable to perform high-level multitasking because it works using single threads which
makes it hard for Node.js to carry out CPU-bound tasks.
It means when you receive a request, the system will work on that request only and take the next
request only after completing the first one. This results in reduced system speed and can cause
extreme delays in processing the requests.

Flexibility
Python is known to be pretty flexible and compatible with many other platforms and programming
languages. Also, the Python framework helps the developers to embed other languages, tools, and
platforms as needed during product development. Instances, where Python can merge well, are C#,
.NET, C, etc
Pros of Python
Faster Development
Python offers a faster interpretation of code to enable faster development. As compared to other
programming languages, Python involves less coding during project development thereby saving a
lot of time in the development phase and allows build fast apps.

Huge Library
Python comes with huge library support to allow app developers to build different applications like
game development, machine learning, web development, etc.
The libraries available with Python are simple to use for developers and facilitate the re-use of
library code to initiate custom development.

Reduced Execution Speed
The speed in NodeJS vs Python, Python is pretty slow as compared to other programming languages
which is because it reduces the execution time. In Python, the code execution takes place line by line
which in turn slows down the overall web app development process.
Cons of Python
Memory Exhaustion
When it comes to web application development, the memory exhaustion rate should be quite less to
boost the performance and speed of an app. With Python, developers face memory consumption
problems at a higher rate which results affects the quality of solutions provided.

Incompatible with Mobile App Development
Well, doing the comparison Python vs NodeJS, we cannot miss out on the fact that Python is
incompatible with mobile app development hence it is not ideal for native app development. Also,
Android and iOS are not compatible with mobile development built on Python.

Comparison using various parameters

Performance & Speed
Node.js
● Having non-blocking and even-based modes,
Node.js helps process countless requests
simultaneously and accelerates the execution
of code.
● When we discuss Node.js vs Python on a
parameter of performance, Node.js helps the
developers to code even from outside the
browser with the help of TCP sockets thereby
increasing its efficiency.
● Node.js development allows fetched data
caching which is not likely to alter. It increases
the speed of development as compared to
Python web development.
● Node.js app responsiveness and performance
are impeccable as you can operate JavaScript
code on the V8 engine.
Python
● One of the main factors while discussing
Python vs NodeJS that cannot be ignored is it
uses one flow of code is utilized by Python
which makes it process the requests slow.
● Python comes with inbuilt architecture that
limits the process of multi-threading.
● Want to recall the data faster? Python can
disappoint you in this case.
● Python may not be the best option if you are
looking for high speed and performance on a
priority basis on your app or need an app that
should process tricky calculations.
On the basis of Performance and speed, in
discussion of Python vs Node.js, Node.js wins
the race.

Scalability
Node.js
● Node.js framework is the perfect choice for app
development as it offers multithreading
through its asynchronous model which offers
higher scalability.
● Node.js utilizes a series of microservices and
modules for its features. Hence, if a business
wants to scale the app, it is just about adding a
couple of modules during NodeJS Web
Development.
● The framework helps you scale vertically &
horizontally.
● Node.js or Python? Well, Node offers plenty of
options when it comes to typing terms. It
means you can pick between weakly-typed
JavaScript or strongly-typed TypeScript.
Python
● One of the major problems with Python is the
Global Interpreter Lock as it doesn’t back multi-
threading. When it comes to scalability it can
be enhanced using imported libraries, but it
cannot fight the natural Node.js scalability.
● When it comes to large-sized projects and
increasing demands of development, Python is
not the best fit.
● When the Python system expands, it becomes
tedious to maintain it.
Again, Node.js is the winner in terms of
scalability.

Absoluteness
Node.js
● Out of the main reasons why Node.js is so
popular is the JavaScript tool. Interestingly, it
helps you work on both front and backend
development using the same programming
language. It proves to work great when it
comes to resources.
● Node.js is helpful in different use cases like
cloud, mobile apps, IoT solutions, and web
apps.
● Also, Node.js comes with cross-platform
functionality which means you can use a
desktop app on Windows OS, Mac, and Linux.
Python
● Python helps you with back-end and front-end
development due to its universal nature.
● Additionally, Python facilitates cross-platform
utilization too. Mac and Linux accompany pre-
configured Python. For Windows, the users will
have to install a Python interpreter.
● This framework is the best option for AI & NL,
and IoT but not the best pick for Python mobile
app development.
Here, among Node.js and Python, both
frameworks are winners.

Architecture
Node.js
● The architecture of Node.js is event-driven and
with asynchronous output and input, it
contributes to faster development. So, Node.js
preferred option for web games and chatbots.
● The framework can handle multiple requests at
the same time. During the process, it will not
block the thread and offers lightning speed too.
Python
● Python proves to be synchronous among
Node.js and Python and hence slow. It means,
if you are developing a project involving a
chatbot, this language will not help you. But, to
execute simultaneous processes you can make
the most of the Python Asyncio library.
● Despite being one of the well-known
programming languages, Python is not event-
based but you can turn it into event-based
using modules such as CPython.
As Node.js is event-driven, asynchronous, and
has non-blocking architecture, the winner is
Node.js.

Extensibility
Node.js
Over a while, Node.js' popularity and the benefits it
brings to businesses have risen due to which you will
see a new tool, framework popping up with this
framework every day. Some of the well-known and
widely used ones are
