Learn functional programming with Haskell. Haskell for Mac provides everything you need in one convenient package.

You get an easy-to-use innovative programming environment optimized to help you understand and develop Haskell code quickly. Regardless of whether you are new to Haskell or whether you like to explore advanced language concepts, algorithms, or libraries, Haskell for Mac will make you more productive than conventional command line-based Haskell systems.

Our secret weapon are our unique Haskell Playgrounds. They facilitate live programming, where your code is constantly executed while you develop and change it. The results of tests and example code are continuously updated and displayed as playground results, regardless of whether they are text, graphics, web pages, or even embedded animations and games.

Haskell for Mac is made for beginners and experts alike.
• The continuous feedback of interactive Haskell playgrounds is ideal for learning functional programming.
• Everybody saves development time due to the fast turnaround as the Haskell code is continuously being type checked and tested against playground code while you edit and refactor.
• Haskell playgrounds provide the ideal environment for experts to quickly experiment with new ideas and to iterate on prototype code.

Haskell for Mac is designed for macOS El Capitan and Sierra.

Haskell for Mac is an integrated graphical development environment for Haskell projects, avoiding arcane installation procedures and cryptic command line tools. It includes a project organizer, a Haskell code editor, and playgrounds for interactive code execution. The code editor provides integrated Haskell support for syntax highlighting (with customizable themes) and auto-completion of function, variable, and type names.

Playgrounds provide immediate and continuous feedback while learning. Haskell is one of the most widely used functional programming languages and perfectly suited to learning functional programming. Haskell for Mac even comes with its own custom-made Haskell tutorial — check it out at

Modern software development is about iterating quickly. While you write, modify, and refactor your Haskell code, it is being continuously type checked and tested. This helps finding mistakes quickly and speeds up development.

Haskell for Mac integrates a purely functional interface to the macOS SpriteKit framework, including its sophisticated animation system and physics engine. Discover how to write games in a functional style. It only requires basic Haskell knowledge and is a great way to learn Haskell!

Whatever you do in a playground, your data is safe. Haskell for Mac uses macOS sandboxing technology to ensure that anything that happens in a playground stays in the playground. Even if you download a Haskell project from the Internet, the playground code cannot access any other data on your Mac, except with your explicit permission.

Haskell for Mac comes with support for web programming, network programming, graphics programming, animations, and much more. Interactively generate web pages, charts, and animations.

Haskell for Mac includes a rich set of over 200 widely used Haskell libraries saving you the trouble of compiling and installing them yourself. However, if you like, it still gives you the flexibility of installing your own libraries. For further technical details, please refer to our product website at

What's New

Version 1.5.1

We have been diligently hunting down some bugs:
• Playground console output handles backspace properly again.
• Better formatting of the result of ':t' and friends in playgrounds.
• Package dependencies don't change when some imported packages are simply not installed.
• Correct colour (orange) for type errors in the gutter (to distinguish them from other fatal errors).
• Documentation links take you to the Stackage documentation for non-bundled LTS packages.
• Fix crash when pasting Unicode characters, such as emoji, in the module editor or playgrounds.
• Faster initial project loading, and no more spurious exceptions in playground results on initially loading or switching to modules.

An easy-to-use Haskell learning and development environment

Brad Larson

If you’ve ever been curious about functional programming, or have been meaning to tinker with the Haskell programming language, this is the place to start.

After working with Swift playgrounds and IPython notebooks, I’m convinced that interactive, compute-as-you-type environments are the best way to learn a new language. I wanted to learn Haskell last year, so I spent days setting up an IHaskell environment to tinker with it. I learned an incredible amount about that language in a short period of time by experimenting with it in an interactive IHaskell notebook.

Haskell for Mac takes all the hassle out of setting up a system like that, and makes it a one-click install. Not only that, but it provides a truly as-you-type evaluation of everything you’re entering. It even contains all the packages you’d need to perform advanced graphing, something that took me over a week and a huge amount of frustration to get right in IHaskell.

The interface is simple yet polished, and makes it easy to organize even multiple-file projects with resources within the playground environment.

I’m really excited about the potential for this application to speed up my Haskell learning and development process. If you have any interest in Haskell or functional programming, you owe it to yourself to get this.

This is a great learning tool!

Clay Borkholm

I come out of a C, C++, C# world, and Haskell has been a challenge for me to noodle...until this product came along. I read a couple of tutorials and overviews and messed with plugins for my traditional dev tooling…but still got kinda lost along the way. This product, together with it’s accompanying tutorial and sample projects, broke down all the barriers. The playground is awesome! It makes figuring out your mistakes (and you will make mistakes) easy and interactive. I found myself writing immensely powerful programs with very little code…demonstrating the power of the language. Some of these programs - very natural in Haskell - would be awkward or difficult with my traditional tools. It’s a credit to the authors to simply illustrate the power of functional programming early. That’s the big epiphany that folks encumbered with preconceptions similar to mine are looking for. I am grateful!

Great way to learn Haskell


I’ve been trying to learn Haskell for a while. However, it was always a pain because I spent just as much time playing around with the text editor, compiling, and whatnot as I did trying to learn how Haskell actually works. This is why I give four stars. It’s trying to fill in the need for a true Haskell IDE, not a bunch of extensions that need configured on some IDE meant for something else.

Is it perfect? No. If you’re trying to learn Haskell it’s better than any other option in my opinion. If you’re an actual Haskell dev it probably won’t fill your needs yet. I won’t say it was worth the money in its current state, but it is actively developed and I’m glad I could support the developer to take this app to where it needs to be.
