Python or Node.js, which technology to opt for Backend Development?

Python VS Node.js, Which one to choose for your web app’s backend development?

Most of the developers choose the backend technology for their web app projects based upon their knowledge and training in a particular technology. Whereas some say it is not often to get the desired results for various businesses. The backend technology and entire tech stack totally depend on the nature of the project and your overall budget as well.

Moreover, using the right backend technology with respect to the project’s use case is imperative. This determines the performance, resource consumption, ease of deployment, and sometimes even the success of the project.

Between Node.js vs Python, both are widely used server-side technologies even though both of them were crafted on various timelines. But before dive into the differences between both, let us understand what exactly is Python and Node.js.

What is Node.js?

Node.js is not a programming language but it is an open-sourced runtime environment for Javascript.  This was initially released in 2009 by Ryan Dahl and the latest version was released in 2009.  The most exciting that makes it so preferable among developers is that it is based on Google’s V8 Engine. Most of the development team loves to work on Node.js to use Javascript on both server and client-side.

What is Python?

On the other side, Python is a full-fledged, high level and object-oriented programming language. And it’s been around 30 years having tons of libraries, APIs, and ancillary tools available. Python is conducive to several programming paradigms and it is widely used for web applications.

Detailed Comparison between Node.js and Python

Understanding which language should be used in which situation is actually the key. So to provide you a better analysis of that we are comparing both the languages based on different criteria:

1. Libraries

This is a set of modules having various features. Developers can incorporate these features to code swiftly. It makes the coding process quite convenient.

  • Node.js- The NPM (Node Package Manager) manages libraries and packages in Node.js. It has the largest software library sources.  It is quite easy to understand and use.
  • Python- It refers to “Pip installs python” is the library of Python and package manager. It is quick, dependable, and simple to use and learn for all the programmers and developers.

Final Take-  In this category, due to its large library sources. Node.js. is a clear winner.

2. Performance

The responsiveness of customer requests is largely defined by the speed and performance of computer languages.

  • Node.js.- Firstly, Node.js speed is exceptional Javascript is directly translated by the V8 Engine. And it codes outside of the internet browser, the app consumes few resources thus increasing the performance. It also provides an opportunity to leverage the power of TCP sockets which you would not see anywhere else.
  • Python- Python and JavaScript are both interpretive languages that mean they are often gets compared with compiled languages like Javascript. Python is not an ideal choice for projects that values speed and efficiency.

Final Take-  Although Python is much simple to understand, it doesn’t have speed optimization, making node.js the right choice here.

3. Scalability- 

The mobile apps you create to be able to accommodate large numbers without crushing. Moreover, when an app is launched there should be good space for improvements and updates.

Without scalability the app becomes stagnant.

  • Node.js- You won’t have to build a massive core using Node.js. Conversely, you develop a collection of microservices and modules, all of which communicate using a compact system and run their own processes.
  • Python- Multithreading must be activated for a program to scale. However, Python employs the global interpreter look: it doesn’t permit (GIL).

Final Take:  Clearly Node.js takes a lead here.

4. Syntax

To have a flexible smartphone app development, you ought to have user-friendly syntax.

  • Node.js- The syntax in Node.js is identical to that of Python. This means if you have prior experience of using python then you would be able to use this quite easily.
  • Python-Python’s syntax is its strongest feature. Therefore programmers who code in this language then you need to generate fewer lines than those who work in Node.js.  Python’s syntax is straightforward and devoid of all the curly brackets. 

Final Take:  Due to its simplicity Node.js takes the lead here.

5. Universality

It means the capability of these languages while handling devices that use web applications.

  • Node.js- The backend development mainly requires Node.js  similarly Javascript is used for front-end development.Node.js has the ability to handle a number of web pages and web apps for a variety of web apps.
  • Python- It is a programming language that could be used for front-end or backend development. Python-like Node.js which is cross-platform, a python program created on mac can be operated on Linux.

Final Take- Here both go hand in hand.


As stated above both programming languages has their own perks and disadvantages. It all depends on the situation and your requirement. Therefore understanding the goal of the project is essential. You can choose the language accordingly and doing that will increase the success rates of your project.
