Node.js vs Python: Which back-end technology should you choose for your next project?

Node.js vs Python; this is one of the hottest discussions that is going over now. These are the two most compared back-end technologies on the internet. Python is the older one and comes with more Fiverr vs Upwork. At the same time, the latter one is the newest back-end technology that is gaining the limelight.

In this post, you are going to explore the differences and similarities between these two back-end technologies. Therefore, if you are a Node.js Developer or python developer, get started without wasting any more time.

Most of the developers, while developing a web app, need back-end technology. Further, the developers choose the back-end technology that suits their fluency, training type, and expertise. As much as it matters for the app development company, the back-end technology also matters to the businesses. Well, it is because you will find the result for your business that you desire if you choose the right back-end technology.

To conclude it more clearly, you can say that a precise back-end technology that suits the project is inevitable. As a business, you would always want your business web app to deliver performance, flexibility, scalability, and much more. Now, this is what brings you to the two most discussed web technologies that include Node.js and Python.

Node.js vs Python: Overview 

Node.js and Python; both of these serve a wide range of businesses and developers. The popularity of both these technologies is increasing. On the other hand, no doubt both of these back-end technologies come from different timelines. Python is a Coding architecture that evolved around 1991. Python was initially created as a server-side coding word. That is what made it a popular choice in the deployment of web app and mobile apps.

Comparing Node.js in contrast, this back-end technology came in 2009. This is a JavaScript runtime environment that aimed to change the JavaScript server-side.

As a business app owner, you would want to choose the best back-end technology that serves you the best. Here is a key difference that will help you determine the best amongst the two.

In brief about Node Js

Node.js is a recent back-end technology that offers you exceptional advantages. Using it in your project development will show you the best outcome. However, Node.js is a completely free JavaScript Run time environment. This is more prevalent for the improvement of apps. The complete back-end technology comes with Google’s V8 engine. That makes it more efficient and result-driven.

On the other hand, Node Js comes with a pre-built interpreter, compiler, and optimizers. Most businesses choose Node.js because of Google’s V8 engine. This engine is quite famous for offering exceptional performance and high-speed apps. Further, Google comes up with this engine with C++ for Google Chrome. Node Js has one primary function, and that is compiling the function of JS to the machine language.

Pros of Node.js

Featured tech stack

As Node.js is completely based on JavaScript, the developer and the business app owners will get all access to the resources of JS. Not only to the resources of Js, but you will also have access to its community and tech stacks. The businesses here get a tech stack that comes loaded with the features. You also get the prospect to design your trading app with the MEAN stack. The MEAN stack is an amalgamation of MongoDB, Angular.js, Node.js, and Express.js; if you don’t know. That implies you get access to the features of all these tech stacks as well.

A great approach to microservice development

The most enjoyable thing about Node.js is it comes with three layers of modules. Thus, the developers get the chance to edit all the multiple modules at one time. This decreases the burden during the maintenance of your business app. This is because; the developers will not go to the layers to edit one module at once. This also saves your time in-app maintenance.

This approach of development is also famous with another name, and that is microservice development. This module system enables the companies to divide and segment their functions into different layers and edit them simultaneously. This brings in qualitative maintenance and also enhances the testing. The business also gets the chance to come up with many new features during maintenance.

Robust environment

The best part about this open-source back-end technology is it offers you an extensive range of plugins, libraries, NP modules, and many more.

Cons of Node.js

Performance issue

Along with the pros, you also get some cons. Node.js is a JavaScript runtime ecosystem that works with all the JavaScript syntaxes. This offers lower CPU consumption time for completing the task. In simple language, when you use Node.js for your back-end runtime, you have to get used to the frequent appearance of CPU connection tasks. Further, the irregularities in the structure also bring more loads to the CPU.

Inefficient tools

The modules of NPM which are not popular yet have not much robust documentation. The developers will lack data that will bring bugs in your app development. Moreover, you end up with poorly created apps.

In brief about Python

Python needs no introduction. Since 1991, this programming language has ruled the development industry. Like Node.js, this programming language also comes with Google’s app engine.

The app module in Python delivers you highly advanced web apps. Further, there are also many more perks that you get from Python. It includes an extensive range of tools, libraries, and a large community.

On the other hand, an extensive range of exceptional tools makes Python a more preferred language for business app development.

Pros of Python

Simple to access 

Python is mostly famous amongst developers because of the easiest syntax you can never find in any other programming language. The syntax appears with simplistic English writing that makes it more comfortable for the developers to acquire. There is also less punctuation used in the syntax which makes it accessible for beginners also. The documentation of Python is also quite clear that reduces time in development.

Chance to learn AI and ML

Python is the exclusive code that empowers developers to receive Artificial intelligence and machine learning. The developers can get huge AI libraries such as Tensorflow and Pylearn2. This helps them learn AI and ML.

Cons of Python

Low pace

A coin has two different sides. Similarly, Python also has two different sides. One side may offer you pros. But you also get cons along with it. One such disadvantage that you get from Python is the low pace of development. This is because; Python has additional layers. This takes much more time to process. As a result, this reduces the pace of Python in server-side operations for the python web development company.

Obstacles in Mobile development 

If you opt for hybrid app creation, it might not be a good choice in such cases. This back-end technology is not an iOS language or Android language. Thus, it becomes really tough to get what you need when it comes to mobile app development. The developers also need more time.

But if you want to use it anyhow, you can go for numerous frameworks that facilitate mobile app development. But the end product will deliver you slower performance.

Node.js vs Python: An in-depth comparison 

Scalability: Node.js vs Python

Scalability in the app development process is all about small growth in the resource necessity when you enhance your web app. Every app, when created, first comes in an MVP version. The MVP version is a lighter form of your web app. This lets you know the bugs and inefficiencies in your app. When you ascend it to the initial version, it is evident that you will need more sources.

The back-end technology that you use chooses must be efficient enough to back you with all resources and the coding environment when you need them. Your business app also scales in the post-development stage. This is when you draw in distinct characteristics and functionalities to your suite. This is also where your back-end technology and the programming language you choose should extend your support.


Node.js offers you extensive support and flexibility to scale your app by creating the core when it comes to scaling. You can scale your app with the same coding environment. Node.js development, as you know, offers you microservice architecture. This empowers developers to edit many layers at the corresponding period.


When it is about Python, you get issues in the thread. The Python has no micro-service architecture. Instead, it comes with a unitary interpreter lock. That implies; the developers will not get the chance to edit and operate multiple threads simultaneously. So, here is a major drawback that you get in Python development services.

Learning chances and Syntax accessibility 

Syntax is the capability of the language or the coding ecosystem that helps you create a set of functions with code. The syntax that offers you easier language and less complex punctuations are always accessible for developers. Further, the lesser code requirement is only possible when the language comes with multiple functions and pre-built operations. This is where the developer doesn’t need to write every code.

On the other hand, the simpler the syntax is, the easier it would be to learn. So, when you are choosing any language, you should know how easy the syntax is.


When it is about syntax accessibility, Node.js is neither too easy nor too steep to learn. If you are already a pro in JavaScript, learning Node.js becomes easier. Some users and developers think that the documentation and the installation of Node.js is a little tedious, as it is an event-driven concept based. But what you can’t deny is this event-driven concept is what makes it more scalable. That is where you get the chance to increase the efficiency of your app.


One of the major USPs of Python is it is easier to learn and understand. The syntax comes in easy English. Thus, even beginners can use it to develop web apps. Further, the developer will also not find any complex punctuations in this programming language. This is what makes it more popular. When it is about writing the functions and program, you will fall in love with Python. The is the perfect place to start! This strategy gives your customers what they want and need most.

Performance and speed

Performance and speed are the two major attributes that you need to compare both these coding environments. Every unit bit of capability of the coding language will always reduce the cost of function for the business. The more speed your app is, the more useful you will find. This is why you should consider the performance and the speed.


When it comes to performance and speed, Node.js is always delightful to use for app development. This is because; the construction of Node.js is a non-blocking pattern of the frame. This, as a result, enables Node.js to execute the codes at a rapid pace without any hassle. Further, this coding language also executes the codes beyond the web browser. Thus, when your business app runs on a web platform, it will offer enhanced performance and a faster pace.


In contrast, the architecture of Python doesn’t allow it for multi-threading. This decreases the pace of development. Further, it also reduces the speed of the processing. As the speed of processing reduces, it shows you an impact on the performance of the app. Thus, if you are considering hiring to hire a python developer, it is time to reconsider then.

Final verdict

Comparing both the back-end technologies based on their pros, cons, and features, you can get one conclusion. That is, if you need hybrid mobile app development, Python is not going to help you. You need Node.js. However, if you want web app development, you can go for Python.
