4Clojure is an interactive website for learning Clojure through problem-solving exercises, built with Clojure, Leiningen, and MongoDB. The hosted site at 4clojure.com has been discontinued, though the source can still be run locally.

Use cases

  • learn clojure by solving interactive problems
  • practice functional programming exercises
  • run a coding challenge site locally
  • find clojure katas and lisp problems
  • teach clojure with hands-on puzzles

When to choose

  • you want to self-host a clojure exercise site
  • you want to browse the problem set source data
  • you want to study how an interactive coding site is built in clojure

When to avoid

  • you want a live hosted practice site - 4clojure.com is down
  • you need a maintained tool with active support
  • you want exercises for languages other than clojure
