While creating a web application, the most common backend frameworks are Node.js and Python. It’s becoming more difficult for product owners to decide between Node and Python as both frameworks are gaining traction. Developers from all over the globe are asking us, “Should I use Node JS or Python for my app?” 

They want to know which language is better regarding security, scalability, and performance. This blog article may assist if you’re deciding between NodeJS and Python in 2023.

What is Node.js & Python

Node.js is an open-source JavaScript runtime environment and library for building server-side web applications. Developed by Ryan Dahl, NodeJs uses an asynchronous, event-driven model and is perfect for developing data-intensive applications. The latest version of Node is 15.14. 

Node.js is very efficient to build scalable apps. Since it is asynchronous, it may process several requests simultaneously without holding up I/O. 

Node has gained huge popularity among developers. With 47% of developers preferring Node JS, it was the most used web framework among developers in 2022.

Python, on the other hand, is an advanced, high-level, object-oriented language. Libraries, application programming interfaces, and other supporting resources abound due to their long history (almost 30 years). Python’s flexibility makes it suitable for a wide range of programming styles and finds wide usage in the enterprise.

It has a large user base, extensive library resources, and robust infrastructure. As a result, it’s a great language for organizations that need to build apps for various purposes that aren’t necessarily linked to one another.

Node.js Vs Python: Advantages

Now that we know how to get about in Node.js and Python let’s compare and contrast their benefits and drawbacks.


Node JS Vs Python


Node js

  • Microservice Architecture

That Can Be Easily Modified Several component and code executions are essential for developing a microservice architecture. For developers working on numerous modules at once, Node.js’s package management offers free components. Microservice development makes it simpler for businesses to preserve their product quality and testing procedures.

  • Solid Technological Infrastructure

Because we are already familiar with JavaScript and how Node.js works, we know that this gives us access to the whole JavaScript stack and its resources. Moreover, you are backed by a robust and lively community. The MEAN technological stack, including Node.js, provides the finest database and front- and backend support for scalable development.

  • Cost-Efficient

As Node.js can be used for both the front end and back end of an application, it may save money by eliminating the need to pay for two teams of developers. As a result, time and money may be saved during development without sacrificing the final product.


  • Rapid Growth

The development cycle may be sped up using Python because of the language’s high readability and speedy code interpretation. The reduced amount of code needed for development means less time spent writing and more time spent optimizing for speed.

  • Flexibility

Python’s compatibility and adaptability to different languages and environments are exceptional. Developers may include additional tools, languages, and platforms whenever necessary throughout product development. Python is compatible with many other languages and frameworks, including .NET, C#, C, and many more.

Node.js Vs Python : Disadvantages


Node js

  • API that is prone to instability

A major language drawback is the incompatibility of Node Js’s back end due to frequent API modifications. The instability-inducing code modifications are directly related to this incompatibility.

  • Callback Hell 

Due to its asynchronous nature, Node.js has the issue of nested callback functions resulting in callback hell. The code quality drops, and it becomes more difficult to fix and maintain whenever numerous callback issues arise.

  • Failure to Perform CPU-Intensive Processing

As Node js operates single-thread, it has difficulty executing tasks constrained by the CPU’s resources. The system will only ever accept one of two requests at a time and always fulfill the first one. There will be a significant delay because of this procedure.




  • Not Suitable for App Creation on Mobile Devices

As Python isn’t a go-to language for building native apps, it can’t be used to create mobile apps. In addition, neither Apple nor Google’s Android platform facilitates Python-based mobile programming.

  • Slow Rate of Execution

Since it reduces execution time, Node.js is slower than other programming languages like Python. Python’s line-by-line approach to code execution makes web applications run slowly.

  • Memory Exhaustion 

Maintaining a web app’s speed and performance requires less memory fatigue than is often the case. Python’s excessive memory usage limits its ability to produce reliable programs.

Node.js or Python: Which one is more popular among programmers?

According to SimilarWeb’s analysis of the top 10,000, 100,000, 1,000,000, and ‘entire’ categories of popular websites, Node.js is the most often used technology. 

According to the Stack Overflow 2022 poll, Node.js is the most popular development environment, while Python is one of the most “liked” programming languages.

When looking at Node.js adoption rates by industry, the poll found it was the most popular in 16 sectors, including Computers, Electronics & Technology, Lifestyle, Arts & Entertainment, and others. 

On the other hand, Python has found widespread adoption in areas as diverse as science and education, engineering, and several others.

Node.js vs. Python: Scalability


Using Node.js, you may forgo using a core because of its adaptability. By breaking up your system into smaller components, or “microservices,” you may scale it independently of the core. These microservices and modules may dynamically execute their processes as your application grows. As a result, the application may be expanded laterally and vertically by adding nodes and resources.



Python’s threading problems are well-known. Since it is based on the Global Interpreter Lock, it cannot run many threads simultaneously. This implies that the sequentially historical procedure must finish before any other process may begin. Python’s dynamic typing is a feature but presents some scalability challenges. As a project expands, it may be challenging for larger teams to keep up with code maintenance.

Node.js v Python: Learning Curves and Syntax


If you’re familiar with Javascript, transitioning to Node.js will be easy. Due to its event-driven programming model, Node.js is often criticized for its complicated installation and documentation. This idea is the foundation for Node.js’s efficiency and scalability.

New developers may require more explanation time to grasp event-driven programming fully. But, once it is taken care of, understanding Node.js is easy.


Python’s universality and simple syntax have been its main selling points. Python code is known to be shorter than Node.js and other languages’ and environments’ counterparts in the business. Python makes it easy to write code.

Node.js v Python: Architecture


We’ve already established that Node.js is a server-side asynchronous programming runtime environment. Because of this, the input-output capability is not halted when a certain process is running. Parallel processing allows you to deploy the program more quickly. Node.js can respond to events as they occur because of its event-driven design.


Python, in contrast to Node.js, lacks such features and multithreading capability. One task must be started and completed before starting another. Because of this, Python becomes quite strict. Python is not intrinsically asynchronous. However, some tools can help you develop asynchronous programs. You must resort to workarounds to achieve the needed asynchronicity in the project.

Node.js vs. Python: Performance and Speed


The non-blocking structure of Node.js has previously been investigated. This advantage makes its implementation less complicated and quicker. Also, Node.js is competitive because it runs code in a separate environment from the browser.

The web-browser app benefits from this increased processing speed by scoring higher on efficiency criteria. Because of this, the program may use TCP sockets and other functionalities that browsers lack.


Another area for improvement is that Python’s design prevents using many threads. As a result, processing times increase since tasks are not executed simultaneously. Python’s syntax is straightforward to implement, but it needs to gain the necessary speed for web-based applications that often get data from the server.

Node.js vs. Python: Library & Development Tools


The Node.js libraries maintained by the Node Package Manager are extensive and thoroughly documented. NPM is the biggest repository of packages in the world, with over 350,000 available.


Pip (short for “Python Installs Packages”) is the library management system for Python. Python libraries are well known to be well-documented and simple to implement. This is true in most cases but not for recently opened libraries. Since newer technologies are less well-documented than older ones, their corresponding libraries may be less dependable.

Node.js v Python: Community support

Community of Node.js

You could assume that the Node.js community is tiny since it is a newer technology. You may be shocked to hear, however, that the Node.js community is both sizable and active around the globe, boasting many skilled Node.js Engineers. With the Node.js community, finding top-notch developers is a breeze.

Python User Group

As Python has been around longer, it would have more users. Python has plenty of talent, from entry-level to expert contributors. Finding qualified developers is made much simpler by the size of the community. When these developers get involved, problems are solved quickly, and the language improves.

Node.js v Python: Extensibility


Node.js’s previous versions may work with Babel to facilitate frontend development. Jasmine may be used for unit-based testing, while can be used for project management. Express is a popular Node.js framework, and you may use Webpack or PM2 to bundle your modules.


As a coding editor, Sublime Text is often used with Python. Robot Framework is useful for robotic testing. Django and Web2Py are two well-known Node.js frameworks that give even more functionality.

Node.js Vs. Python: Universality


As Node.js can be used for both backend and frontend development using Javascript, it fares quite well in this area. Node.js may be used to build just about anything: websites, desktop applications, mobile apps, and even solutions for the cloud and the Internet of Things.


Because of its more streamlined syntax, Python is well-suited for all kinds of projects except mobile applications. Many developers are switching to Python for developing  Internet of Things (IoT) application and cloud applications.

Node.js v Python: Error Handling


Due to its ability to run several processes concurrently, Node.js may make debugging difficult.


Python’s simpler syntax and absence of simultaneous operations make scanning for faults and mistakes easier.

Node.js v Python: Data Processing


Node.js is the platform of choice if your app’s use case generates large amounts of data. The runtime environment’s cutting-edge technology is perfect for programs that regularly transfer and process large amounts of data. Node.js has the advantage because it can execute in parallel and perform I/O operations without hiccups.


Python’s sluggish data processing speed is a result of its simplistic syntax and single-threaded design.

Node.js vs. Python: Use Cases 

Uses of Node.js: 

  • Streaming Apps for the Web
  • Single Page Applications
  • Real-Time Chat Applications 
  • Tools for Constructors to Work Together in Real Time

Uses of Python: 

Python’s flexibility means that entrepreneurs may pick and choose the use cases they need for their apps in light of their own business models. Some common Python applications are listed below.

  • Programming and Website Design
  • Test Automation
  • Web crawlers
  • Computer Vision, OCR, and Image Processing
  • Data-Driven Game Design for the Web
  • Uses for Artificial Intelligence and Machine Learning

What Factors to consider while choosing Node.js or Python?

There are several aspects to consider before settling on a language for your backend Application. Here are a few examples:

  • How well-versed each member of your staff is in each language. Using Python for the backend may be preferable if your team has more familiarity with it.
  • The kind of task you’re doing right now. You can use Python if your project has a lot of data or needs a lot of processing power.
  • Each language’s supporting resources, such as libraries and frameworks. You may be limited to employing a single backend language if you rely on a library or framework supporting just that language.
  • How well each language functions. Python is quicker for development, whereas Node.js is better suited for use in a live environment. Nevertheless, this is only sometimes the case and might depend on the specifics of your project.
