nREPL is a Clojure network 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 powers many well-known development tools.
- Start an nREPL server (e.g. with
- Connect to the server using any nREPL client (e.g. CIDER, Calva, vim-fireplace)
- Start hacking!
See the documentation for way information on the subject.
You can find nREPL's API documentation on cljdoc.
Extremely stable. nREPL's protocol and API are rock-solid and battle tested. nREPL's team pledges to evolve them only in backwards-compatible ways.
That being said, there were a few organizational changes related to the transition out of clojure-contrib that everyone has to keep in mind:
[nrepl "0.3.1"]is a drop-in replacement for
[org.clojure/tools.nrepl "0.2.13"](notice the different artifact coordinates).
[nrepl "0.4.0"]changes the namespaces from
1.0.0 release will include fixes for all previously-reported
but languishing nREPL issues. Future releases will focus on supporting
the needs of the essential tools of the Clojure(Script) ecosystem
(e.g. Leiningen, Boot, CIDER, Cursive).

Does nREPL support ClojureScript?
Yes and no. The reference nREPL implementation is Clojure-specific, but it can be extended with ClojureScript support via the Piggieback middleware. In the future there may be implementations of nREPL that target ClojureScript directly.
Does nREPL support other programming languages besides Clojure?
Thank you to all our backers!
