Python vs Node.JS: Which One is Best for Your Project?

Programmers choose a backend technology for their app development projects based on their training or fluency in a particular technology. While this might be convenient but it’s often not the right approach as the entire tech stack needs to be chosen as per the project.

Node.JS vs Python are popular server-side technologies even though both of them were developed on different timelines and designed for multiple objectives. Python was designed as a server-side programming language that one can deploy to mobile and web applications. In contrast, Node.JS is a JavaScript runtime environment that drastically changed JavaScript on the server-side.

As a development company, you might wonder which one to choose for your project. So to make the right call, it’s essential to study these technologies where one would outdo the other and vice versa. In this blog we will provide you with a detailed overview of both these technologies. Also, we will do a quick comparison of Python v/s Node.JS to make it easier for you to choose the best.

Overview of Python v/s Node.JS

Guido van Rossum created Python for the first time at Centrum Wiskunde & Informatica (CWI) in the Netherlands. It is a back end and front end programming language that dynamically supports multiple programming paradigms. Python is convenient to create apps for mobile, desktop, and web that comes with exhaustive packages and libraries.

Developed by Ryan Dahl, Node.JS is useful for building efficient and scalable web applications that run on JavaScript and can be used for both front ends and backend development. Node.JS is a JavaScript runtime environment which was created on Google Chrome’s high-performance JavaScript engine.

A detailed outlook on Python v/s Node.JS

We all are aware by now that NodeJS is an open-source running time method where it can range the competencies of JavaScript to every server out there. From the time it was introduce, NodeJS expansion is developed to be famous and well-known among several developers not nationally but even globally. It is well-known for designing APIS and creating fresh mediums which could be utilize in the world of the internet. check hire nodejs developers to find a developer to help you in your project.

The communal place of NodeJS is present on the awareness of allocation. This is quite simple to segment library code correspondences in an educational, practical, permissible, and technical method. NodeJS expansion even arrives with the Node Package Executive, raising to a source of near to 50,000 correspondences. It creates a simple to admittance a NodeJS designer’s already wrapped resolution to the difficulties that developers face, or an explanation to an additional problem.

Popularity of a backend technology plays an important role in determining whether you will use it in your project. And when you hire Python developers for your project, then you have to decide which language has a significant talent available in the market. So, let us help you to make a right choice by providing you a detailed comparison of Python v/s Node.JS:

1.   Performance

Speed and performance are the most essential aspects of the scaling of an application. And every single bit of efficiency helps reduce the operating costs.

Node.JS comes with a faster and simpler execution process. On top of this, Node.JS executes the code outside of the web browser. Furthermore, Node.JS allows the app to pull features such as TCP sockets, which are otherwise not available in the browsers.

Python’s architecture prohibits multi-threading because of which the processing speed gets slowed down that makes it hard for the processes to run parallel. Moreover, Python’s syntax is easy to learn and execute, it is not fast enough for applications that frequently recall data from the web-server.     

2.   Suitable for which app?

Node.JS contains an event based architecture which makes it more suitable for the apps that contain many concurrent requests, frequent data shuffling or heavy client-side rendering. IoT solutions, complex single page applications and real time chatbots and messengers are the best example of this. 

On the contrary, Python is suitable for the development of both large and small development projects. You can use it to build data science apps that include data analytics, visualization, voice and face recognition systems, neural networks, machine learning systems and image processing software.

You can also use Python to build 3D modelling software and games. Both technologies let you develop a number of apps. Which one is more suitable that solely depends on your project requirements?   

3.   Scalability

Scalability is another aspect that you need to consider when you hire offshore development team for your project. Scalability is the capacity of an application to serve the increasing requests without compromising the performance.

Node.JS provides you with enough flexibility to avoid the core. Because of this, you can create a set of modules and microservices instead of building a core and scaling everything around it. Hence, you can scale the app horizontally by adding nodes to the existing ones or you can expand it vertically by adding resources.  

Python is built on the global interpreter lock that does not allow it to operate multiple threads at a single time. This means that you cannot run another process before the historical process gets over.

4.   Technical Architecture

Node.JS is a runtime environment that contains server-side asynchronous programming. Architecture defines the common principles to adhere to the framework. Node.JS has a single-threaded architecture.

While Python follows “cpython” using the interchangeable code modules. Python does not support multi-threading. This means you have to run and finish one process before another. This makes Python a little stringent. 

5.   Universality

You can access a web app via many devices and gadgets. With such diversity, it’s expected that the development language needs to be universal and sophisticated.

Python is bundled with Linux and macOS which makes it ideal for frontend and backend cross-platform development. It is an advanced programming language for web and desktop development.

Node.JS is used for frontend and backend development of web apps, translating to consistent use of JavaScript on both ends. Node.JS develops a variety of cross-platform applications. Furthermore, it reduces development costs and efforts.  

6.   Libraries

Libraries are the major reason why app development has gained attention from the technocrats within the last few decades. If you create a code once then you shouldn’t have to recreate it. Instead, integrate this code directly from a library in your program while only writing code for the features that you want to create.

Talking about the libraries, Node.JS contains Node Package Manager which has well-documented libraries. With over 1.3 million packages, Node Package Manager becomes the biggest package repository worldwide.

Python uses Pip (Pip Installs Packages) to handle libraries. With the number of packages, Python covers a wide range of categories such as data science, calculation, image processing, and much more.

7.   Community 

Before we dive deep into the community of Node.JS and Python, let us understand what it means. Basically, a community is a group of developers engaging with a specific technology. Community constantly updates popular libraries, runs debugging actions, and also adds the latest features.

Node.JS is relatively a new form of technology that presumes the community to be small. However, the Node.JS community is quite big and globally active with highly skilled and experienced Node.JS developers. This highly active community makes it easier for you to hire Node.JS developers with great expertise.   

Apart from this, Python, being the older language, naturally has a larger community that contains both junior and senior-level developers. The active participation from these developers results in swift solutions and overall improvement of the language. 


Making a suitable choice between Node.JS and Python can be a challenge for you as both have their own special features and benefits that may affect your decision. So, choose a language or runtime environment that proves to be handy.

The ideal way to sort out this dilemma is by focusing on the end-use of your product. For this, you need to figure out the essential features of your product and how you will execute them.
