Nextjs vs Nodejs​: Which Backend Framework to Choose in 2025

Today, businesses rely on interactive and dynamic web applications to improve their online presence. One of the most popularly used backend technologies is JavaScript which not only creates real-time web apps but also helps developers improve their coding experience. 

As of 14 June 2024, nearly 98.8% of websites use JavaScript.

63.61% of developers use JavaScript for client-side and server-side app development.

Global brands (Google, YouTube, Facebook, LinkedIn, Twitter, etc.) use JavaScript to develop compelling websites.   

JavaScript offers several frameworks for efficient developer experience. 

Choosing the right JavaScript framework is a strategic decision for overall success. Two popular backend JavaScript frameworks are- Next.js vs. Node.js.

However, Node.js is a runtime environment that runs JavaScript code outside the browser. And Next.js is a React-based framework for building dynamic and hybrid applications. Both offer unique benefits and are suitable for different use cases.

To build modern-age applications, developers must understand where both technologies differ and which one to choose in 2025.

What is Node.js?

GitHub- 108k+ stars, 3500+ contributors

40.8% of backend developers prefer Node.js to build high-end, dynamic, and real-time applications. Since 2009, Node.js has evolved with a strong community improving it over the years. 

Source 

Here are a few things that you must know about Node.js.

A runtime environment that executes JavaScript on the server side.

Built on Chrome's V8 engine, which is the main reason behind Node.js’s high-speed and efficient applications.

Can handle many concurrent connections.

Has npm (Node Package Manager)- a set of libraries and tools for extended functionalities.

Works well for data-intensive applications that need quick responses.

Supports both vertical and horizontal scaling to meet growing demand.

Easily integrates with JSON for seamless data exchange.

Supported on most platforms, including Linux, Windows, Unix, macOS, and more.

Key Features

Here are some key features of Node.js

Source 

Event-driven, asynchronous, non-blocking I/O Model- allows Node.js to handle many concurrent connections efficiently. It also manages resources and I/O operations asynchronously. It means the system will process other requests without waiting for the response from a slower I/O process. It improves the app’s performance and responsiveness. It makes Node.js apps highly scalable.

Modular design- Node.js modular design allows developers to share and reuse code, significantly reducing development time and improving the developer’s experience. 

Compatibility across platforms- you can use Node.js across platforms like Mac OS X, Linux, and Windows. It helps developers create a single codebase and deploy it across platforms ensuring the same functionality and responsiveness.

Built-in debugging tools- one of the most prominent features is its built-in debugging tools, allowing developers to identify and fix issues instantly. 

NPM (Node Package Manager)- it comes with Nodejs installation. It is a package manager that allows developers to access millions of packages to add more functionalities to a simple app. You can simply install a package for any functionality and use it within your app without developing it from scratch.

Built on Chrome’s V8 engine- it is the reason that Node.js is extremely powerful, efficient, and fast, allowing faster execution of JS code while handling heavy applications with great ease. 

Benefits of Using Node.js for Your Business

High performance- Node.js can handle multiple concurrent requests without consuming many resources, making it suitable for developing applications that require high performance and scalability. The V8 engine improves performance and response time. PayPal reduced its response time by 35% using Node.js.

Improves developer's experience- with Node.js, developers can easily use the programming language (JavaScript) to create both backend and frontend. It means developers do not have to switch to another language and frameworks. Node.js has a large ecosystem that allows developers to create a wider range of applications, improving developer’s experience.

Cost-efficient development- Node.js can save up to 58% of development costs. As it can handle many requests at the same time, it requires less resources. It lets you reuse the code, reducing time-to-market and development expenses. This is why, Node.js has become the go-to option for businesses that need cost-efficient yet powerful modern-age solutions.

Growing community- since 2009, Node.js has grown with strong community support. This community has contributed towards Node.js improvements, making it a better technology to meet modern-age development needs. As a developer, you will find packages and libraries to stay ahead by incorporating the latest trends in web app development. 

Easy deployment and hosting- Node.js makes it easy to deploy applications on cloud platforms like Heroku, AWS, and Azure. These services simplify the deployment process, allowing businesses to scale their apps as their user base grows. With hosting providers tailored for Node.js, companies can install and manage their apps with minimal setup and maintenance.

Disadvantages of Node.js

Performance bottleneck- Node.js is great at handling many requests at once. But the challenge is, that it uses a single thread to process tasks, impacting performance when dealing with complex calculations. These tasks can create a "bottleneck," slowing down the entire system.

Limited support for databases- Node.js was first created to work with web apps, which meant it didn't support many databases except for MongoDB. It might find it difficult to use Node.js with other types of databases or in different kinds of applications. It limits its flexibility in some cases.

Callback hell- Node.js uses asynchronous tasks and callbacks, but this can make the code messy and hard to follow, especially in complex apps. When callbacks are nested too many times, it creates a "callback hell," that is difficult to manage.

Memory leaks- Node.js relies on a garbage collector to manage memory, but sometimes has memory leaks. It means they don't release memory properly, resulting in performance issues and making the app unstable.

Despite its challenges, top brands like LinkedIn, eBay, Netflix, GoDaddy, Groupon, Uber, NASA, and Walmart, use Node.js for seamless experiences. Today. More than 1 million websites use Node.js.

What is Next.js?

GitHub- 127k stars and 3500+ contributors.

As a new technology in the market, Next.js has gained much popularity since 2017. 17.9% of developers prefer it. Unlike Node.js, Next.js is a React-based server-side rendering framework. 

Source 

Here are a few things you must know about Next.js.

Developed by Vercel

Open-source framework

Used for creating server-side rendered (SSR) apps and static site generation (SSG) web apps 

Based on the principle of “Build once, runs everywhere”

Offers unique features like route pre-fetching and automatic code splitting

built on top of React and runs on top of Node

Offers tools and features for building high-performance, scalable, and optimized web applications.

Improves developer's experience to build fast and efficient web applications

Features of Next.js

Here are some key features of Next.js.

App Directory (New File System Routing)- The new App directory introduces a new file-based routing system, which offers better flexibility and improved server-side rendering (SSR). It allows developers to organize components and pages more efficiently and to define layouts that are shared across different pages. This feature is part of the move towards a more modular and composable approach to building applications.

Source 

React Server Components (RSC)- it allows developers to render some parts of the app on the server and send only the required HTML to the client. This results in faster page loads and better SEO, as the server can handle complex logic. Server components allow for a more optimized rendering process, minimizing the amount of JavaScript sent to the client.

Automatic code splitting- Next.js automatically splits your code into smaller parts, so only the necessary CSS and JavaScript files are loaded for each page. This makes the files smaller and helps the page load faster. As a result, developers can build fast and efficient web apps with Next.js.

Edge Functions & Middleware- Edge Functions are small, fast-running server-side functions deployed closer to the user on the edge network, improving performance, especially for globally distributed applications. Middleware runs on the edgel, allowing developers to handle tasks like authentication, redirects, and A/B testing with low latency.

Source 

Image Optimization Enhancements- it automatically optimizes images based on the user's device and network conditions. The latest updates have improved performance and flexibility in how images are handled, with automatic WebP conversion and better support for blur-up effects.

Hybrid Rendering- With Next.js, developers can use different types of rendering approaches- SSR (server-side rendering),  SSG (static site generation), and CSR (client-side rendering) within a single app for optimizing performance, SEO, and user experience.

API Routes- Next.js allows you to create backend API endpoints directly within the project, enabling full-stack development without needing a separate server. This makes building complex applications easier by simplifying data fetching, processing, and handling.

Better SEO and Head Management- Head Management improvements in Next.js allow developers to control meta tags, titles, and other important SEO elements more efficiently. This helps in improving SEO by making the meta tags dynamic and context-specific.

Webpack 5 Support- Next.js now fully integrates Webpack 5, offering better build performance, improved caching, and support for the latest JavaScript features, resulting in faster builds and smaller bundle sizes.

Turbopack (Alpha)- Turbopack is a new bundler from the creators of Next.js, designed to replace Webpack. It's faster and more efficient, especially for large projects. Currently, in alpha, it promises significantly faster build times and hot module reloading (HMR).

Incremental Static Regeneration (ISR)- This allows developers to update static pages without rebuilding the entire app, ensuring up-to-date content without impacting the speed of static generation. 

Benefits of using Next.js

Source 

Improved SEO- Next.js can generate fully rendered HTML on the server using Server-Side Rendering (SSR). This means pages load faster and search engines can easily read and rank them. With Static Site Generation (SSG), pages are pre-built as static HTML during the build, making them even faster and better for SEO.

Blazing fast speed and performance- Next.js has helped streaming app Twitch to reduce its initial load time by 50%. It uses many features like SSR, SGR, and automatic code splitting to load pages quickly and offer a smooth user experience.

Accessibility- due to SSR, web apps have more accessibility. Users can use a reader screen to access the web page content easily.

Improved developer’s experience- Next.js features like a flexible and powerful routing system, an optimized build system, and a large ecosystem of resources, tools, and libraries, lead to the developer’s productivity and experience to build more robust apps. 

Enhanced security- as Next.js SSG pre-generates the content and serves the static HTML file. It reduces the risk of security vulnerabilities and attacks.

Disadvantages of Next.js

Complexity- Next.js has many powerful features, but setting it up can be tricky, especially for new developers. It might take longer to get started and configure everything, which can slow down development.

Browser Compatibility- Next.js uses modern JavaScript, which may not work well with older web browsers. Developers need to make sure their app works on the browsers their users are likely to use.

Dependency on React- Next.js is built on React, so you need to understand React well to use Next.js effectively. If you're new to React, this can be challenging.

Next.js can be used to build many different types of projects, such as:

Complex Web Applications

Web Platforms

Multi-Market Solutions

Advanced eCommerce and Retail Platforms

SaaS Products

Interactive User Interfaces

This is why brands like Nike, Hulu, Binance, Twitch, TikTok, and Vercel use Next.js for better performance.

Next.js vs. Node.js: Detailed Comparision

Here is a detailed Next.js vs Node.js comparison.

1. Next.js vs Node.js performance

Web Performance is necessary to keep users engaged. About 40% of online users tend to leave a website that takes longer than three seconds to load.

Node.js is a suitable option for building fast apps as it can handle many tasks at once. It uses an event-driven system, meaning it doesn’t get “stuck” waiting for things to happen. To make your code even faster, you can write asynchronous code that lets multiple tasks run at the same time. Node.js also helps you store and retrieve data efficiently and can avoid issues like memory leaks. Tools like caching and content delivery networks (CDNs) improve load times by serving files closer to users. For high-traffic apps, load balancing spreads the work across multiple servers.

Next.js is a framework built on top of React that makes websites even faster. It has built-in tools for improving performance, like lazy loading images and loading pages in the background for smoother transitions. It also lets you control SEO elements like page metadata, helping search engines understand your content better.

For large apps, Next.js provides monitoring tools to track performance and identify issues before they cause problems. It also includes a bundle analyzer to help you reduce the size of your app and send only the necessary data to the browser. By using CDNs to serve static files, Next.js helps further speed up your site.

2. Next.js vs Node.js scalability

Scalability in web apps means making sure your app can handle many users at once without slowing down or costing too much. It’s about increasing app performance as more people use it, without using too many resources. However, scalability differs from response time—your app can handle many requests but still take longer to respond, or it can respond quickly but struggle with heavy traffic.

In Node.js, scalability challenges include serving files, scheduling tasks, and using resources effectively. To solve these:

Use a CDN (Content Delivery Network) like CloudFront to serve files faster.

For repeating tasks, use a task scheduler like Agenda.js instead of basic timers.

Use Node.js clustering to divide the work between multiple processes, improving performance without overloading.

For Next.js, scalability is achieved by:

Caching: Use CDNs for static content, server-side caching for dynamic content, and client-side caching for API calls.

Load Balancing: Spread user traffic across multiple servers to avoid overloading.

Optimizing Databases: Use techniques like indexing, query optimization, and caching to reduce database load.

Auto-Scaling: Set up your app to automatically add or remove server instances based on traffic or usage.

3. Node.js vs Next.js: Development Speed

Node.js provides a basic platform to build server-side applications using JavaScript. You have to set up a lot of things manually, like routing, handling requests, and serving static files. This means you have more flexibility, but takes more time to set up and develop the app from scratch.

Next.js: It is a framework built on top of Node.js and React. It offers many built-in features like server-side rendering (SSR), static site generation (SSG), routing, and image optimization. These features make development faster because a lot of common tasks are already handled for you. You don’t have to set up everything from scratch, so you can focus more on building the app itself.

Next.js is faster for development because it provides ready-made tools and features, while Node.js gives you more flexibility but requires more setup.

4. Node.js or Next.js for frontend

Node.js: Node.js is mainly used for backend development, meaning it runs on the server to handle things like saving data to a database, managing user logins, and processing API requests. While it can be used to build parts of the front end (like rendering web pages on the server), it's not specifically designed for that purpose.

Next.js: Next.js is a framework built on top of React and is specifically designed for front-end development. It helps you build fast websites with features like server-side rendering (SSR) and static site generation (SSG). These features make websites faster and better for SEO (search engine optimization). Next.js also makes it easier to manage routing (pages) and other common frontend tasks.

If you're building a website's frontend (what users see and interact with), Next.js is the better choice because it’s made for that. Node.js is mostly for backend work, but it can help with some frontend tasks if needed.

5. Routing

Routing is like a map for your website. When a user asks for a specific page (like by typing a URL), routing decides where the request should go and what should be shown in response. It helps direct the user's request to the right place in your application.

There are two main ways to handle routing in Node.js: with a framework or without one.

With a Framework (like Express.js): Express is the most popular framework in Node.js for routing. It makes things easier by giving you a set of tools to handle routing quickly. You can use methods to define routes (like /home or /about), and each route can have a function that runs when someone visits that page. For example, if someone goes to /home, the app will show the homepage content.

Without a Framework: If you don't use a framework, you have to build your own server and routing system. You'll manually handle the URLs and decide what happens when a user visits different pages.

Next.js Routing: In Next.js, routing is simpler. It uses a file-based routing system. This means that every file you put in the pages folder automatically becomes a route. For example, if you create a file called about.js, Next.js will automatically link it to /about on your website. This system also handles dynamic pages, where parts of the URL can change based on data, like showing a user’s profile page based on their ID.

6. Developers experience

Developer experience (DX) is about how easy and enjoyable it is for developers to work with tools and technologies. If tools are good, developers can build things faster and with fewer problems.

Node.js and Next.js both focus on improving the developer experience in different ways:

Node.js: Node.js lets developers create anything they need, but it can be a bit complex at first. It has NPM, a huge library of tools and packages, making it easy to find solutions for problems. While it’s flexible, beginners might find it tricky until they get used to it.

Next.js: Next.js is simpler and more ready-to-use. It helps build fast websites with features like SEO-friendly pages and easy routing. It does a lot of the work for you, so you don’t have to set things up manually. It’s great for developers who want to build apps quickly without dealing with too many details.

When to Use: Next.js vs. Node.js

Node.js is a cross-platform that runs on the V8 engine and executes Javascript code outside a web browser. It also allows developers to use Javascript to write command-line tools and run scripts server-side to produce dynamic web page content before the page is sent to the user’s web browser. 

.js is a standard filename extension for Javascript code, but Node.js doesn’t refer to a file in this context.

Overview of Node.js

Node.js allows the creation of web servers and networking tools using Javascript and modules that handle various core functionalities. Javascript is the only language that Node.js supports natively. As a result, Node.js applications can be written in Clojure script, Dart, and others. It is officially supported on macOS, Linux, and Microsoft Windows 8.1. 

Node.js brings event-driven programming to web servers and allows the development of fast web servers in JavaScript. It connects the ease of a scripting language with the power of Unix network programming. It was built on top of Google’s V8 Javascript engine since it was open-sourced under the BSD license. The Node.js developer community has developed web frameworks to accelerate the development of applications. The frameworks include Socket.IO, Derby, Express.js, Feathers.js, and others. 

Modern desktop IEDs provide debugging features for Node.js applications. These IDEs include JetBrains, Microsoft Visual Studio, or TypeScript with Node definitions. It is supported across several cloud hosting programs like Google Cloud Platform, Joyent, and others.

Install NodeJS on Linux Using NVM

This is the best way to install Node.js. NVM is a bash script used to manage multiple Node.js versions. It allows us to install and uninstall Node.js and switch from one version to another. The best thing is we can install any available Node.js version of our choice using NVM.

Install Node.js on Linux using your distribution’s package manager

It is available in the default repositories of most Linux distributions. If you want to have a stable Node.js on your Linux, you can install it using the distribution package manager.

On Arch Linux and its derivatives like Antergos, Manjaro Linux, run the “$ sudo pacman -S nodejs npm” command to install it. 

On RHEL, CentOS, you need to enable the EPEL repository first. $ sudo yum install epel-release and then install Node.js using $ sudo yum install nodejs npm command.

All You Need To Know About The NodeJS Framework

NodeJS is an open-source, cross-platform JavaScript runtime environment that enables server-side execution of JavaScript code. It was developed by Ryan Dahl in 2009 and has since gained immense popularity in the web development community. NodeJS is built on the V8 JavaScript engine, which powers Google Chrome, and it allows developers to use JavaScript for both front-end and back-end development. What is NodeJS? At its core, NodeJS is a runtime environment that allows developers to execute JavaScript code outside the browser, on the server-side. This means that you can use JavaScript to build server-side applications, handle requests, and perform tasks traditionally reserved for server-side languages like Python or Ruby. Key Features of NodeJS NodeJS comes with a rich set of features that make it a popular choice for web developers: Asynchronous I/O NodeJS uses a non-blocking, event-driven I/O model, which allows it to handle multiple requests concurrently. This asynchronous I/O capability ensures that NodeJS applications remain performant and responsive, even under heavy loads. NPM (Node Package Manager) NPM is the package manager that comes bundled with NodeJS. It allows developers to easily install, manage, and share reusable JavaScript modules, saving time and effort in building complex applications. Single Threaded, Event-Loop Architecture NodeJS follows a single-threaded event-loop architecture, which enables it to efficiently handle a large number of concurrent connections without creating multiple threads. This makes NodeJS highly scalable and resource-efficient. Cross-Platform Compatibility NodeJS is designed to be cross-platform, meaning it can run on various operating systems, including Windows, macOS, and Linux. This flexibility makes it an ideal choice for developers working in different environments.

Code Reusability With the extensive collection of NPM packages available, developers can easily reuse existing modules to build complex applications quickly. This promotes code reusability, saving valuable development time and effort. Easy Learning Curve for JavaScript Developers Since NodeJS uses JavaScript for both front-end and back-end development, JavaScript developers can easily transition to building server-side applications without having to learn a new language or framework. Scalability NodeJS's non-blocking I/O model and single-threaded architecture make it highly scalable. It can efficiently handle a large number of concurrent users without sacrificing performance or responsiveness. Limitations of NodeJS While NodeJS offers many benefits, it's essential to be aware of its limitations as well: CPU-Intensive Tasks NodeJS may not be the best choice for CPU-intensive tasks, as its single-threaded nature can lead to performance bottlenecks when dealing with extensive calculations or data processing. Callback Hell Due to its asynchronous nature, NodeJS code can sometimes become complex and difficult to manage, leading to what developers refer to as "callback hell." This can make the code harder to read and maintain. Immaturity of Some Modules While NPM provides a vast library of modules, some may be less mature or poorly maintained, which could lead to compatibility issues or security vulnerabilities. Common Use Cases for NodeJS NodeJS is a versatile framework that finds applications in various scenarios: Real-time Applications NodeJS excels in building real-time applications, such as chat applications, collaborative tools, and online gaming platforms, where instantaneous data exchange is crucial. APIs and Microservices NodeJS's lightweight and fast nature make it an excellent choice for developing APIs and microservices that need to handle a high volume of requests with minimal overhead. Single-Page Applications (SPAs) When paired with front-end frameworks like React or Angular, NodeJS is commonly used to build single-page applications that offer a smooth and responsive user experience. Streaming Applications NodeJS's ability to handle data streams efficiently makes it well-suited for applications that deal with large files or multimedia content, such as video streaming platforms. NodeJS vs. Other Server-Side Frameworks NodeJS is not the only server-side framework available, and developers often debate its merits compared to others like Python (Django/Flask), Ruby (Ruby on Rails), or Java (Spring Boot). Let's briefly explore some key differentiators: Performance NodeJS's event-driven architecture gives it a performance advantage, especially in handling concurrent connections, compared to some traditional server-side frameworks that use multi-threading. Scalability NodeJS's ability to handle a large number of concurrent connections efficiently makes it highly scalable, allowing applications to scale easily as the user base grows. Learning Curve For JavaScript developers, NodeJS provides a smooth transition to server-side development, as they can leverage their existing knowledge of the language and its ecosystem. Community and Libraries NodeJS's active community ensures continuous development and improvement of the framework and provides access to a vast number of open-source libraries and tools. FAQs What is Node Package Manager (NPM)? NPM is a package manager bundled with NodeJS that allows developers to install, share, and manage reusable JavaScript modules. It simplifies the process of integrating third-party libraries into NodeJS applications. Can I use NodeJS for Front-End Development? While NodeJS is primarily used for server-side development, it can also be used for front-end development with tools like Webpack and Babel. However, its main strength lies in server-side applications. Is NodeJS suitable for CPU-Intensive Tasks? No, NodeJS may not be the best choice for CPU-intensive tasks, as its single-threaded nature can lead to performance issues when dealing with extensive computations. How can I handle Callback Hell in NodeJS? To avoid callback hell, developers can use modern JavaScript features like Promises or async/await, which provide a more organized and readable way to handle asynchronous operations. Is NodeJS Production-Ready? Yes, NodeJS is widely used in production environments by companies of all sizes. It has proven to be stable, efficient, and reliable for building scalable web applications. Can I use NodeJS with a Relational Database? Yes, NodeJS can be used with relational databases like MySQL, PostgreSQL, or SQLite. There are various libraries and ORM (Object-Relational Mapping) tools available to facilitate database interactions. Conclusion NodeJS has revolutionized the way developers build web applications, enabling them to use a familiar language, JavaScript, for both front-end and back-end development. Its asynchronous and event-driven architecture. Read the full article

Day 003 - corrupted

I am very very tired, like wowzers...

Well... I had to do a lot honestly, like setting up CICD. Which is very easy if you're using Github actions, and then I had to clean up our repository. I deleted all of the feature branches leaving only development and main branch, and restructured the github repository and redid the README

Now I'm just trying to install the latest versions of nodejs on this ec2 linux instance, I didn't expect it to be so hard or maybe I"m doing it wrong. The easy way is to "apt install nodejs npm" but that just installs very old versions. I need at least 16.

I'm sure I can get the work done in time for tomorrow's client meeting, but in order for that to work I'll just do this one simple idea. Open an instance with the latest nodejs version, and then git clone the project and run the instances on different ports.

Hmph... today is finishing the services, afterwards is just an integration job. Sooo exhausting, but I gotta do it in a sprint. Just because I'm no stallion anymore doesn't mean I don't have that will.

So today let's finish our services today, and then I'll have to look into the frontend and see how I can integrate on my own. Relying on others may not be my strongest point, I've always valued independence. Let's kick ass today, a lot of coding is ahead of us

Kind of. Especially for desktop use, hugely out of date packages are at the least inconvenient and at worst a huge source of security risk. The way stable-release distributions like Ubuntu, Debian, CentOS, OpenSUSE Leap/SLE, and so on mitigate this in theory is "backporting", a very time consuming process of keeping track of upstream security fixes and then figuring out how to apply them to an older codebase without breaking compatibility.

Now, you can do this, and the Enterprise Linux business model basically relies on it, but there's a lot of issues. For one, maintainers often don't choose their version based on any particular stability of the underlying package, it's often just the most recent working package version when the stable release goes out, so even if say, the upstream project releases a Long Term Support version of their project, Red Hat or whoever might choose a different version for their stable release and now you still have to backport fixes in addition to the upstream team.

That might sound like a weird edge case but this is what happens with the goddamn Linux Kernel! There's official upstream LTS kernel versions but most of the stable distributions just pick their own versions and maintain them on their own!

There's also the inconvenience. This was a huge thing with Node; in the early days nodejs shipped like four new major versions a year, so if you got Ubuntu 16.04 and installed node from the repos, you could be out of date multiple major versions and have a completely different featureset. So you still have to go get an upstream release, only now you have just installed this antique version for ??? no good reason.

There are times this isn't such a huge issue, many packages don't change this fast, but there are plenty that do, and finding out that the version you got from Ubuntu is a year out of date often means you have to dig around for legacy docs, or you'll discover that some new project you're working on straight up can't function unless you go compile your own version anyway.

Stable has its benefits, there are reasons why Enterprise likes having stable API and compatibility targets, but it's not like it doesn't introduce its own complex set of problems. Part of the reason for the move to containers is to allow you to mix and match your dependencies for different systems efficiently on one machine without having to manually keep track of all those dependencies.

Reminded why I never use Ubuntu in my personal life! Installed fzf from the repos on my work laptop and it's version 0.44! The current release of fzf is 0.58! Don't ship packages that are over a year out of date! Just say no!

 The company offers shared, business, and VPS-hosting currently only for Linux based.  It offers a variety of payment methods, including Bitcoin and other cryptocurrencies!

 Two key points about hostinger.  Positives:

 Performance: their speed, uptime, response times are one of the best in this class.  Part of this feature is due to the presence of 7 data centers located across 5 continents: North America (USA), Europe, UK, Brazil, and Asia.

 Custom control panel: Hostinger has a neat and extremely easy-to-use custom control panel built, which enables very fast development, feature releases and feedback loop with clients.

 Support: Hostinger's customer success department provides 24/7 support and is ready to answer all questions within seconds.  All agents are highly skilled and professional.  They have live chat assistance, which is available once you become their client, and log into their system.

 WordPress improvements: HTTP / 2, IPv6 enabled, PHP7, nginx caching, gzip compression, spam and threat detection.  This enables hostinger to serve up to 3 times more requests per second.

 Technological advantages:

 - HTTP / 2 support for nginx and dual Apache web server architecture

 - Dual cache (custom memcached + nginx cache)

 SSD raids for maximum I / O speeds

 - Daily backups

 The latest PHP 7+

 - HA network preparation

 - cloudlinux + lve container for each account

 Pricing: Hostinger is well known for always having low pricing, and special promotions.  It does offer a standard 30 day money-back guarantee.

 Payment methods: credit card (Visa, MasterCard, American Express, Discover, etc.);  Paypal cryptocurrencies are supported (Bitcoin, Ethereum and many other cryptocurrencies);  Other local payment methods are also supported in the local markets.

 A pair of important notes.  Negatives:

 The lowest package includes only 1 database and 1 email box only, not SSL (which is a must for any websites nowadays), which is why we don't include this plan in our list.

 Their second plan, currently on sale for $ 2.95 a month, also doesn't include free SSL, all of their lesser packages don't include daily backups.

 They do not have a price renewal guarantee like some of the other service providers listed in our directory, and their renewal price appears to be 3-4 times higher than their initial price!

 Also, the standard shared hosting packages are not developer friendly as they do not include support for python, ruby, postgeneral, nodejs.
