CIDER aims to provide an interactive development experience similar to the one you’d get when programming in Emacs Lisp, Common Lisp (with SLIME or Sly), Scheme (with Geiser), and Smalltalk. ... - 7
Joker
Small Clojure interpreter, linter and formatter
...(Note use of --file, in this case, to ensure <filename> is not treated as a <socket> specification for the reply.) Our goal is to be suitable for scripting (lightweight, fast startup). This is something that Clojure is not good at and my personal itch I am trying to scratch. Also, to provide some tooling for Clojure and its dialects. Joker has linter mode which can be used for linting Joker, Clojure and ClojureScript code. - 8
core.logic
A logic programming library for Clojure & ClojureScript

Timbre
Pure Clojure/Script logging library
Java logging can be a Kafkaesque mess of complexity that buys you little. Getting even the simplest logging working can be comically hard, and it often gets worse at scale as your needs become more sophisticated. Timbre offers an all Clojure/Script alternative that's fast, deeply flexible, easy to configure with pure Clojure data, and that just works out the box. No XML. Easily filter logging calls by any combination of: level, namespace, and appended. Zero overhead compile-time level/ns elision. Useful built-in appenders for out-the-box Clj+Cljs logging. Powerful, easy-to-configure rate limits and async logging. ... - 15

Clj-kondo
A linter for Clojure code that sparks joy
A linter for Clojure code that sparks joy. Clj-kondo performs static analysis on Clojure, ClojureScript and EDN, without the need of a running REPL. It informs you about potential errors while you are typing. To detect lint errors across namespaces in your project, a cache is needed. To let clj-kondo know where to create one, make a .clj-kondo directory in the root of your project, meaning on the same level as your project.clj, deps.edn or build.boot. - 20
Kibit
There's a function for that
kibit is a static analysis tool for Clojure/ClojureScript that detects code patterns that can be rewritten more idiomatically.
