The world's largest digital bank, Nubank, runs 110 million customers on a Clojure backend. Babashka has entered the shell scripting arena. shadow-cljs has absorbed the entire npm ecosystem. Clojure 1.12 brings qualified method invocation, Babashka 1.4 ships GraalVM native images, and ClojureScript with re-frame and UIx 2 forms a React 18 stack. Datomic Pro is now free, XTDB 2.0 adds bitemporal SQL — and REPL-driven development turns out to be the most LLM-friendly paradigm of all. This deep dive covers the entire 2026 Clojure ecosystem end to end, and how Nubank scales 5,000 Clojure microservices.

Clojure 1.12의 qualified method invocation, Babashka 1.4의 GraalVM 네이티브 이미지, ClojureScript + re-frame + UIx 2의 React 18 스택, Datomic Pro 무료화, XTDB 2.0 bitemporal SQL — 이 모든 것이 어떻게 한 언어 안에서 작동하는지, REPL 주도 개발이 왜 LLM 시대에 가장 적합한 패러다임인지, 그리고 Nubank가 어떻게 Clojure로 마이크로서비스 5,000개를 운영하는지까지 심층 분석한다.
