Should Web Developers Know Haskell

Should Web Developers Know Haskell?

It is not necessary to learn Haskell for web development, there are many other server-side programming languages that you can use in place of Haskell. You can use programming languages such as Python, PHP, Javascript, Java, Ruby, Kotlin, Elixir, Scala, C#, Go, etc.

Since its development by Lennart Augustsson and his colleagues in 1990, Haskell grew in popularity and usage in many software development fields. But in recent times, its popularity and usage have decreased drastically. Only 2.12% of all professional developers use Haskell.

According to statistics from, “Haskell is used by less than 0.1% of all the websites whose server-side programming language we know.” Its popularity and usage continue to decrease month over month.

A 2021 Stack Overflow survey revealed that Haskell is loved by 53.00% of professional developers versus 47.00% of professional developers who dreaded it. This show that Haskell is still loved by programmers although its popularity among professional developers is decreasing.

The Haskell programming language is a general-purpose, purely functional programming language, with type inference and lazy evaluation. Haskell was designed with an orientation toward teaching, research, and industrial applications.

Haskell is simple to learn than other programming languages like C, C++, or Java. Its syntax is easy to understand and there is a lot you can do in a few lines of code. Haskell applications are modular and very easy to maintain.


Haskell is used to build web applications, mobile applications, revision control systems, System tools development, compilers, blockchain platforms, cryptography, etc. Haskell was used to implement the Cardano Blockchain platform, it is also used at Facebook to implement anti-spam programs.

Although Haskell is not popular for web development projects, there are quite a number of Haskell-based web frameworks that you can use to make your web development process easy. These web frameworks include Snap, Yesod, Spock, Scotty, Obelisk, Happstack, Mis0, Servant, etc.

Haskell is used by quite a number of popular websites and companies, some of them include Meta, Target, Standard Chartered, Barclays, Github, Microsoft, CircuitHub,, Tramcloud, and many others.

Since Haskell is not very popular for web development, you can use other alternatives for programming the server-side logic of your web applications. Learning Haskell for web development is not necessary, it is completely optional and you can do without Haskell.


There are many server-side programming languages that you can use as alternatives to Haskell. Here are some of the popular ones:


PHP is the most popular server-side programming language, it powers more websites on the internet than the rest of the server-side programming languages put together.

According to statistics from, “PHP is used by 77.5% of all the websites whose server-side programming language we know.” PHP website usage has been decreasing over the years, but it will take more than 25 years to decrease to 50% at the rate at which it is decreasing.

To make your development process easy, quick, and well structured, you can use PHP frameworks such as Laravel, Symfony, CodeIgniter, Slim, Zend, Phalcon, CakePHP, and many others.

PHP is used by many popular platforms and websites such as WordPress, Drupal, Wikipedia, Facebook, Slack, Etsy, Tumblr, MailChimp, etc. PHP is simple to work with and it is a great alternative to Haskell.


Node.js is an open-source Javascript runtime environment that runs on the V8 Engine. It is cross-platform and is used to run Javascript outside of the web browser. Node.js is used by web developers for server scripting.

It is commonly used in the Javascript stack such as the MERN (MongoDB, Express.js, React, Node) and MEAN (MongoDB, Express, Angular, Node) Stack. To make it easy to work with Node.js, frameworks such as Express.js, Sails.js, Koa.js, etc. are popularly used.

You can use Node.js as an alternative to Haskell, especially if you like working with Javascript.


Python has an easy-to-understand syntax that makes it easy to write code, getting started with Python is very easy and straightforward. Python is used a lot by web developers for backend development. According to a 2021 Stack Overflow survey, Python is the third most used programming language by professional developers.

Python Django is one of the most popular web development frameworks, it was used to build part of the Instagram backend. Other python web frameworks that can be used in place of Haskell include Flask, FastAPI, CherryPy, Falcon, etc.


Go is an open-source programming language supported by Google, Go is used in web development to power fast and scalable web applications. It is a good alternative to Haskell. Some of the companies using Go are shown in the image below

You can also use Java as an alternative to Haskell for server-side programming. Java is used by many websites, especially in the enterprise world. You can learn more about how Java is used in Web Development in our article DO YOU NEED JAVA FOR WEB DEVELOPMENT?


Since its invention in 1995 by Yukihiro “Matz” Matsumoto of Japan, Ruby has grown in popularity and usage to become the third most widely used server-side programming language after PHP and ASP.NET.

According to statistics from, “Ruby is used by 5.9% of all the websites whose server-side programming language we know.” Ruby usage for making websites has been decreasing over the years, but it is still one of the popular choices for many companies and startups.

Ruby is easy to work with than Haskell, its syntax is simple, elegant, and English-like, similar to that of Python. Getting started with Ruby and Ruby on Rails for web development is very easy and you will serve a lot of development time by using this language and its framework.

The popular online E-commerce store builder Shopify was written in Ruby (Ruby on Rails). Other popular websites using Ruby include Twitter, Github, Basecamp, Airbnb, Dribbble, Hulu, Kickstarter, Zendesk, Fiverr, SoundCloud, and many others.

There are many other alternatives to Haskell that I have not listed here. The availability and usage of many other powerful server-side programming languages and frameworks show that you can work on web development projects without using Haskell.


It can be seen that even though Haskell is used in web development, learning Haskell for web development is not necessary, you will be better off using other server-side programming languages.

It is worth noting that less than 0.1% of all websites use Haskell for server-side logic, leaving a huge room for other server-side programming languages such as Python, C#, Ruby, Node, Go, Scala, PHP, Java, etc.

If you want to make a website but you do not want to write any server-side or frontend code, you can use Website builders like WordPress, Shopify, Bubble, Wix, Squarespace, etc. to do all the heavy lifting for you. You can make powerful websites without writing any line of code.
