GHC 9.10 (May 2024) and 9.12 (Dec 2024) pushed the compiler another notch faster, and GHCup is now the officially recommended installer, simplifying the choice between Cabal 3.14 and Stack. IHP delivers a Rails-class full-stack experience, Servant has become the standard for typed HTTP APIs, and Effectful is rapidly displacing the mtl style. The ORM lineup is Persistent / Beam / Esqueleto, parsing is Megaparsec, JSON is Aeson, testing is hedgehog / tasty / hspec, and we still have Liquid Haskell refinement types and Hasktorch ML at the edges. Pandoc remains in John MacFarlane hands, Cardano is run by IOG, GitHub uses Haskell in Semantic. This article is the 2026 map of the modern Haskell stack on one page.

GHC 9.10(2024년 5월)과 9.12(2024년 12월)로 컴파일러는 한 단계 더 빨라졌고, GHCup이 공식 권장 설치 도구로 자리 잡으면서 Stack과 Cabal 3.14 사이의 선택이 단순해졌다. IHP가 Rails 같은 풀스택 경험을 제공하고, Servant가 타입드 HTTP API의 표준이 되었으며, Effectful이 mtl 스타일을 빠르게 대체하고 있다. ORM은 Persistent / Beam / Esqueleto, 파서는 Megaparsec, JSON은 Aeson, 테스트는 hedgehog / tasty / hspec, 그리고 Liquid Haskell의 refinement types와 Hasktorch의 머신러닝까지. Pandoc은 여전히 John MacFarlane이 들고 가고, Cardano는 IOHK가 운영하며, GitHub은 Semantic으로 Haskell을 프로덕션에 쓴다. 이 글은 그 모든 조각을 한 페이지에 모은 2026년판 모던 Haskell 지도다.
