Free Haskell to Crystal Converter
How to use this tool?
This free online converter lets you convert code from Haskell to Crystal in a click of a button. To use this converter, take the following steps -
- Type or paste your Haskell code in the input box.
- Click the convert button.
- The resulting Crystal code from the conversion will be displayed in the output box.
Examples
The following are examples of code conversion from Haskell to Crystal using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.
Example 1 - Is String Palindrome
Program that checks if a string is a palindrome or not.

Example 2 - Even or Odd
A well commented function to check if a number if odd or even.

Key differences between Haskell and Crystal
| Characteristic | Haskell | Crystal |
|---|---|---|
| Syntax | Haskell has a unique syntax that is based on mathematical notation and is known for its strong type inference. | Crystal has a syntax similar to Ruby, with some additional features like static typing. |
| Paradigm | Haskell is a purely functional programming language. | Crystal is a statically typed, object-oriented programming language with some functional programming features. |
| Typing | Haskell has strong static typing with type inference. | Crystal has static typing with type inference, but also allows for dynamic typing when needed. |
| Performance | Haskell is known for its high performance, especially in terms of memory usage. | Crystal aims to have a similar performance to statically typed languages like C or C++, but with a more expressive syntax. |
| Libraries and frameworks | Haskell has a growing ecosystem of libraries and frameworks, although it may not have as many options as more popular languages. | Crystal has a smaller ecosystem of libraries and frameworks compared to more established languages, but it is growing. |
| Community and support | Haskell has a dedicated and active community, with good support available through forums, mailing lists, and online resources. | Crystal has a smaller community compared to more popular languages, but it is growing and has active support channels. |
| Learning curve | Haskell has a steep learning curve due to its unique syntax and functional programming concepts. | Crystal has a relatively low learning curve, especially for developers familiar with Ruby or other similar languages. |
Frequently Asked Questions
How do I convert Haskell to Crystal?
Paste your Haskell code into the input box, confirm the languages are set to Haskell and Crystal, and click Convert. CodeConvert AI analyzes your Haskell code and generates equivalent Crystal code in seconds, preserving the original logic and structure.
What are the main differences between Haskell and Crystal?
Haskell and Crystal differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Haskell construct to its closest Crystal equivalent. See the comparison table below for the key differences between Haskell and Crystal.
Is the converted Crystal code accurate?
The AI produces high-quality Crystal code that preserves the behavior of your original Haskell code and follows Crystal conventions. It handles common patterns, data structures, and idioms for both Haskell and Crystal. For large or performance-critical code, review and test the Crystal output before using it in production.
Can I convert an entire Haskell project to Crystal?
You can convert Haskell files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Haskell to Crystal. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Crystal back to Haskell?
Yes. CodeConvert AI converts in both directions, so you can convert Crystal to Haskell just as easily using our Crystal to Haskell converter. Try the Crystal to Haskell Converter
Is the Haskell to Crystal converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Haskell to Crystal without an account for up to 5 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
