Node.js vs Python: Which technology is better


Node.js vs Python: Which technology is better?

Selecting the right programming language is essentially important while you are searching to develop an app. Hence there are various business owners as well as developers who find themselves in a dilemma to pick between Node.js vs Python. It is difficult to choose the right backend technology for your project. 

You don’t need to worry much since here you will find a comparison between these backend technologies in detail to help you make the best decision. But before that, let us first have a look at the overview of Node.js and Python.


Node.js is open-sourced runtime environment specifically for JavaScript, which was released in the year 2009. It is a virtual machine that uses Google’s V8 engine. In addition, it has in-built compilers, optimizers, and interpreters.

V8 is known for its continuously increasing performance and high speed. Google has designed the engine with C++ for Google Chrome. The key objective of Node.js is to make use of JavaScript functions using one machine code.

If you are opting for Node.js, then you will definitely need Node js web hosting. Hence you will have to go with Java specialized hosting provider, which provides you access to host your node.js applications. You will have to find the best and cheap node js hosting provider for the one-click installation of Node.js applications. Hence you can find many affordable node js web hosting with high-quality features.


Python is one of the top-level programming languages which was released in 1991. Google established Python, and it operates on Google’s App Engine. It enables you to develop web applications with Python. Furthermore, it also gives you the benefits of various tools, including libraries that many Python developers use.

This wide variety of tools and libraries creates Python a perfect programming language for businesses. Hence you can develop applications with uncorrelated use cases. Make sure you get the best Python hosting for the Python framework. Discover the suitability of python hosting and how it can work best for you.

Detailed Comparison of Node.js Vs Python:

Now let us compare both backend technologies on the basis of the following criteria. It will give you a fair picture of which technology will be better for you.

Node.js vs Python: Speed and Performance

The non-blocking architecture makes everything convenient for the execution process, making it simple and fast. Moreover, by using Node.js, you can implement codes that are outside the web browser. Therefore it makes an app suitable to operate on a web browser process. Therefore fast speed and high performance impact the efficiency metrics. It also allows the app to use features such as TCP sockets which are not available on other browsers.

Node.js development provides caching fetched data which makes it faster in comparison with Python web development. Moreover, Node.js takes far less loading time since it is very responsive. Hosting also plays a significant role in performance and speed. Therefore you will have to select the best node js web hosting company. Select a company that offers multiple node js web hosting plans to the customers. They need to have an expert support team working 24/7 to resolve queries. It should guarantee an above 99% uptime guarantee with some additional add-ons as well.

Python is an innate architecture that restricts multithreading. Hence it affects the speed as well as performance. Since it does not go parallel, it reduces the general processing speed. Even if it is easy to learn and execute Python syntax, it will still not be fast enough for applications to recollect data from the webserver.

Hence if you are considering high speed and performance, you should definitely opt for Node.js.

Node.js vs Python: Scalability

Node.js supports creating a set of microservices. With such microservices, you can simply communicate using a lightweight mechanism that runs on its own process. The development process in Node.js is tremendously flexible since you can easily add more modules and microservices. Also, you can horizontally and vertically scale up your Node.js web app. For horizontal scaling, you can add different nodes to the system. Likewise, for vertical scaling, you can add extra resources to your existing nodes. Node.js also provides you several other options, especially when it comes to typing since you can make use of JavaScript or strongly typed TypeScript.

Python does not allow multithreading which is important for scaling the app. Instead, it makes use of the Global Interpreter Lock (GIL). Even if there are several threads present, GIL allows the Python interpreter to perform several tasks at one time. Moreover, it also makes sure that only one thread runs at one time. However, since Python does not have proper memory management and is not thread-safe, it is compelled to use GIL even if it has a negative impact on performance. Moreover, Python is dynamically typed, and such kinds of languages are not preferable, especially when it comes to big projects. Therefore it becomes extremely difficult as it grows.

While considering scalability, Python might not be a good option for you in some cases; hence you can opt for Node.js.

Node.js vs Python: Error Handling

It is tough to avoid all kinds of errors while you are writing codes. Hence it is feasible and transparent enough to identify errors since it is an important programming tool. Node.js is very effective when it comes refers to efficient error management. It has top-quality command in finding exceptions that occur for code applications.

Python is superior to Node.js when we talk about error handling. It is due to the reason that it takes comparatively less amount of time for troubleshooting errors and bugs.

Hence Python is clearly better when it.

Node.js vs Python: Libraries

Node.js npm (Node Package Manager) is solely responsible for managing the packages in Node.js. Since it controls over 1.3 million packages, it is one of the largest repository packages in the world. Moreover, it also reflects how extensible it can be.

Packages and libraries in Python are managed using pip, which is one of the default package installers of Python. Unfortunately, the number is immensely increasing since there are more than 220 thousand packages with a wide range of categories, including calculation, image processing, data science, etc.

Hence it is very evident that Node.js provides a larger number of packages and is a clear winner. Also, overall, Node.js is better than Python.
