• Compile-time macros.
• Embeddable.
• Learning Fennel from Clojure
• Quite popular in game development

Lux

A functional, statically-typed Lisp that will run on several platforms, such as the Java Virtual Machine and JavaScript interpreters.

• Implemented in Clojure.
• Inspied by Haskell, Clojure, ML.
• Actively developed.

Wisp

A little Clojure-like LISP in JavaScript.

• Try it
• Native JavaScript types and function calls.
• Maintenance mode.

Joker

Joker is a small interpreted dialect of Clojure written in Go. It is also a Clojure(Script) linter.

• Source code
• Fast startup time.
• Sane error messages and stacktraces.
• Batteries included: send HTTP requests, read and parse JSON, work with file system, start external processes, etc.

Ferret

A Hard Real-Time Clojure for Lisp Machines.

• Implemented in Clojure.
• Compiles to ISO C++11.
• Restricted subset of Clojure.
• Embedded systems focus.

ki

A functional programming language that expands into JavaScript through a very thin layer of sweet.js macros.

• Source code
• Implemented in Javascript
• Intermix LISP code with JavaScript.
• Dormant project.

Toccata

A Clojure dialect that compiles to native executable using the Clang compiler.

• Self hosted.

Carbonate

Clojure-inspired Lisp that transpiles to Ruby.

• Implemented in Ruby.
• Tries to cover Ruby's functionality with more concise code forms.
• Dormant project.

slisp

Modern Lisp variant inspired by Python, Clojure & Arc.

• Implemented in C++.
• Modern, OO, both statically & dynamically typed.
• Dormant project.

timl

TimL is a Lisp dialect implemented in and compiling down to VimL, the scripting language provided by the Vim text editor.

• Implemented in Vim's scripting language.
• Dormant project.

Apricot

Apricot is a programming language inspired by Clojure and Lisp that runs on the Rubinius VM.

• Implemented in Ruby.
• Dormant project.

Gherkin

A functional programming language and interpreter written in GNU Bash 4.

• Implemented in Bash 4.
• Dormant project.

Rhine

An OCaml compiler for an untyped lisp.

• Implemented in OCaml.
• Runs on the LLVM JIT.
• Dormant project.

Small Clojure Interpreter

A tiny implementation of Clojure in Clojure.

• Made to evaluate code from user input where eval is unsafe or unavailable.
• Early development.

Jank

jank is strongly compatible with Clojure; its host is C++ on top of an LLVM-based JIT, with a built-in gradual type system.

• Any Clojure library without interop will compile into your jank projects.
• Built on an LLVM-based JIT. With AOT enabled, both statically and dynamically linked executables can be generated.
• Use your favorite nREPL editor plugin. jank uses an LLVM-based JIT to compile machine code on the fly.
• Built-in gradual type system which allows for malli-style type annotations which result in static type analysis.
• Work in progress

Mal make-a-lisp

Mal is a Clojure inspired Lisp interpreter. Mal is implemented in 63 languages.

• Try it

Notable/usable implementations follow.

malc

Mal (Make A Lisp) compiler

• Compiler for Mal, written in Mal itself.
• Compiles a Mal program to LLVM assembly language (IR), and then uses the LLVM optimizer, assembler and gcc linker to produce a binary executable.

miniMAL

A Delightfully Diminutive Lisp. Implemented in < 1 KB of JavaScript with JSON source.

• Try it.
• Uses JSON syntax.

mal/php

• Implemented in PHP.
• Interop with & runs where PHP does.

mal/ruby

• Implements the #mal IRC bot.
