Elixir 1.18 ships a set-theoretic types preview. Phoenix 1.8 lands Scope APIs and ships daisyUI by default. LiveView 1.0 finally went GA. Ecto stabilizes as the canonical DB layer. Oban dominates job processing (with the contentious 999 dollars per year Pro upgrade). Broadway runs Kafka/RabbitMQ/AMQP/SQS data pipelines. Membrane handles audio/video. Igniter does safe code mods. Bumblebee brings Hugging Face Transformers to Elixir. Nx, Axon, and Explorer assemble a BEAM data-science stack. Livebook is the Elixir notebook. Tidewave, unveiled by Jose Valim in September 2025, is Elixir-native LLM serving. The thirty-year-old strengths of BEAM — actors, fault tolerance, soft real-time — explain why Discord, WhatsApp, parts of Toss, BabyDragon in Korea, Drecom and DMM in Japan all picked it. This is the full 2026 stack from VM to GenServer to LiveView to Tidewave in one read.

Elixir 1.18의 set-theoretic types 프리뷰, Phoenix 1.8의 Scope API와 daisyUI 기본 적용, LiveView 1.0의 정식 출시, Ecto가 만든 DB 추상의 안정성, Oban의 잡 처리(그리고 Pro $999 논란), Broadway의 Kafka/RabbitMQ/AMQP 데이터 파이프라인, Membrane의 오디오/비디오 처리, Igniter의 코드 변환, Bumblebee가 가져온 HF Transformers, Nx와 Axon과 Explorer로 짜는 BEAM 데이터 사이언스, Livebook 노트북, 그리고 José Valim이 2025년 9월 공개한 Tidewave 추론 플랫폼까지 — BEAM의 액터/내고장성/소프트 리얼타임이라는 30년 묵은 강점이 왜 지금 다시 매력적인지, 그리고 한국의 토스/BabyDragon, 일본의 ドリコム/DMM/任天堂 일부가 왜 Elixir를 골랐는지 한 호흡으로 풀어낸다.

This deep dive covers Erlang/OTP 27 with string interpolation and persistent_term improvements, the OTP 28 preview, Cowboy 3 HTTP server, the pure-Elixir Bandit, the RabbitMQ-built Khepri (a Raft-based Mnesia successor), partisan as an alternative to distributed Erlang, Nerves for embedded and AtomVM for ESP32, the statically-typed gleam language and its Lustre web framework, and how WhatsApp, Klarna, Discord, Riot, Cisco, and Akamai actually use BEAM in production.

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.
