This page summarizes the projects mentioned and recommended in the original post on

Our great sponsors
  • SonarQube - Static code analysis for 29 languages.
  • Scout APM - Less time debugging, more time building
  • SaaSHub - Software Alternatives and Reviews
  • TreadMarks

    Battle tank combat racing!

    I'm looking to port some code from the game Tread Marks and ideally keep it functional.

  • distributive

    Dual Traversable

    Seems like a neat signature. Is it an instance of some deeper concept or property? Is there a general typeclass for it? It looks a little bit like distribute from distributive.

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • write-you-a-haskell

    Building a modern functional compiler from first principles. (

    I feel like Write You A Haskell was set out to introduce some of these foundational concepts in the right order: lambda calculus, to system-f to core - but that's more of a skeleton, right? What about logic? proofs? Is there anything else ... that can all be put together to create a "course" of some sort to master the theoretical concepts that Haskell stands upon?

  • constraints

    Tools for programming with ConstraintKinds in GHC

    If it's anywhere, I'd expect it in constraints, but it's not Dict and it's not Forall.

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
