This page lists promising resources for use with Clojure, etc. In general, the descriptions are adapted from the resource's web site(s), etc.

IDEs, etc.


clj-brackets, a small plugin by John Pradeep, evaluates Clojure expressions in Adobe Brackets, a web-based text editor. It uses wrepl, a Leiningen plugin which starts a REPL which responds to HTTP POST requests.


Clooj is a small, simple IDE (integrated development environment) for the Clojure programming language. It has some interesting features (eg, looking up functions), but its REPL linkage appears to be broken for Clojure 1.4 (sigh).


Emacs Prelude

Emacs Prelude has the goal to ease the initial Emacs setup process and to provide you with a much more powerful and productive experience than the one you get out of the box. By using Emacs Prelude you're basically getting a "Get me out of the Prelude, I just want to use Emacs" card.

Note: Emacs Prelude requires GNU Emacs 24.x; for Macs, this is available from

Swank Clojure

swank-clojure is a server that allows SLIME (the Superior Lisp Interaction Mode for Emacs) to connect to Clojure projects.

Note: This project is no longer under active development. New users are strongly encouraged to try out nrepl.el instead.


Cursive Clojure

Cursive is the Clojure IDE that understands your code. Advanced structural editing, refactorings, VCS integration and much more, all out of the box.



Catnip is a Leiningen plugin providing a fully functional text editor and REPL environment geared towards web development with Clojure and ClojureScript.


Leiningen is for automating Clojure projects without setting your hair on fire.


lein-idea is a Leiningen plugin to create project files for use in IntelliJ IDEA.


lein-oneoff simplifies the process of writing simple Clojure scripts (eg, handling dependencies and the classpath).


Nightcode is the only thing you need to create Clojure and Java projects for the command line, the desktop, the web, and Android -- besides JDK 6 or above. Whether you choose to make a Clojure or pure Java project, Nightcode will use its built-in copy of Leiningen to build and run your code.

Light Table-based

Light Table

Light Table is a new interactive IDE that lets you modify running programs and embed anything from web sites to games. It provides the real time feedback we need to not only answer questions about our code, but to understand how our programs really work.

See Also:



nREPL is a Clojure *n*etwork REPL that provides a REPL server and client, along with some common APIs of use to IDEs and other tools that may need to evaluate Clojure code in remote environments.

nrepl.el is an Emacs client for nREPL, the Clojure networked REPL server. It's a great alternative to the now deprecated combination of SLIME + swank-clojure.

Session, by Kovas Boguta, is a web-based Clojure REPL that stores the interaction history in Datomic. This is a fascinating venture in documentation, social computation, etc.

Sublime Text-based

Sublime Text is a text editor for Mac OS X. It will feel very familiar to users of TextMate, but it appears to be better supported (eg, works on Lion and Mountain Lion). It provides a simple but (IMHO) adequate environment for Clojure development. See Getting Started with Sublime Text 2 for more information.



foreplay.vim is Tim Pope's alternative to VimClojure. See my Howto for installation notes, etc.


VimClojure is one of the most sophisticated editing environments for Clojure. It provides syntax highlighting, indenting and command completion.

See my VimClojure Howto for installation notes, etc. Also see vim-scripts/VimClojure on GitHub.

Alternatively, look into foreplay.vim.

Tools, etc. (formerly known as clojure.contrib.trace) is a Clojure trace tool. It defines tracing macros/fns to help you see what your code is doing.


The folks at Prismatic have open sourced [][Schema]], a Clojure(Script) library for declarative data description and validation..
