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.

NodeJS vs Python : Pros and Cons

Pros of Node.js

Microservice development flexibility

If you are planning to develop a microservice model, you need to have numerous executions of development and components. 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.


Node.js support both the front and back end of an app which means you don’t need to hire Nodejs developers for the app development. It directly saves development costs and speeds up the 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.

Cons of Node.js

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.

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, 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.

Pros of Python


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

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.

Cons of Python

Reduced Execution Speed

The speed of Node.js vs 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.

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, 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.

NodeJS vs Python : Comparison using various parameters

Nodejs vs Python Performance Parameters

NodeJS vs Python : Performance And Speed


  • 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.


  • 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, Node.js wins the race.

NodeJS vs Python : Scalability


  • 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.
  • 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.


  • 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.

NodeJS vs Python : Absoluteness


  • 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.
