List of Lisp-family programming languages

The programming language Lisp is the second-oldest high-level programming language with direct descendants and closely related dialects still in widespread use today. The language Fortran is older by one year. Lisp, like Fortran, has changed a lot since its early days, and many dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme.

A Computational Logic for Applicative Common Lisp consists of a programming language, an extensible theory in a first-order logic, and a mechanical theorem prover
Arc 2008 Paul Graham Dialect of Lisp developed by Paul Graham and Robert Morris
AutoLISP 1986 David Betz Built to include and use with the full version of AutoCAD and its derivatives
BBN LISP 1966 BBN Based on L. Peter Deutsch's Lisp implementation for PDP-1, which was developed from 1960 to 1964; in time language was expanded until it became its own separate dialect in 1966; later renamed Interlisp
Chez Scheme 1985 R. Kent Dybvig Scheme dialect
Chialisp 2019 Bram Cohen Lisp-like language, focus on security and auditability; commonly used on Chia blockchain to lock funds in smart coins until spent and released by their owner, enabling behavior similar to a smart contract
Chicken 2000 Felix Winkelmann Scheme dialect
Clojure 2007 Rich Hickey Lisp dialect, emphasizes functional programming; runs on Java virtual machine, Common Language Runtime, and JavaScript engines; like other Lisps, treats code as data (homoiconicity) and has a macro system
ANSI Common Lisp 1994 ANSI X3J13 committee Common Lisp enhanced and standardized, published in ANSI standard document ANSI INCITS 226-1994; to the features of Common Lisp, it adds the loop macro, and the Common Lisp Object System (CLOS) to provide object-oriented programming paradigm with multiple dispatch (multimethods), and method combinations; runs on many platforms: Unix, Linux, macOS, Windows, JVM, JavaScript, Unix/C, LLVM/C++, Android, iOS
Common Lisp 1984 Lisp dialect first standardized in a book, "Common Lisp the Language", by Guy L. Steele, developed as a standardized and improved successor of Maclisp; statically and dynamically scoped; strongly-typed, allows (optional) type declarations; separate namespaces for functions versus data variables, a trait often named Lisp-2; object-oriented programming is possible via libraries such as Flavors, CommonLOOPS, and later CLOS; treats code as data (homoiconicity) and has a macro system; The reader is extensible via reader macros
Dylan 1992 Apple Computer Mostly based on Scheme and Common Lisp, was designed as system and application programming language by Apple; first used to write an operating system and applications for internal prototypes of the later released Apple Newton computer; first official version of Apple Dylan also had s-expression based syntax; Apple collaborated with partners to develop this language
Emacs Lisp 1985 Richard Stallman Often referred to as Elisp, used by GNU Emacs and XEmacs text editors to implement most editing functions built into Emacs
EuLisp 1990 Statically and dynamically scoped Lisp dialect developed by a loose formation of industrial and academic Lisp users and developers across Europe; the standardizers intended to create a new Lisp "less encumbered by the past" (compared to Common Lisp), and not so minimalist as Scheme, and to integrate the object-oriented programming paradigm well
Fennel 2016 Calvin Rose Compiles to Lua. Full Lua compatibility: Easily call any Lua function or library from Fennel and vice-versa.
Franz Lisp 1980 Richard Fateman Written at UC Berkeley by the students of Professor Richard J. Fateman, based largely on Maclisp and distributed with the Berkeley Software Distribution (BSD) for the Digital Equipment Corp (DEC) VAX
Game Oriented Assembly Lisp (GOAL) 2000s Andy Gavin Video game programming language developed by Andy Gavin and the Jak and Daxter team at Naughty Dog; written using Allegro Common Lisp; used in developing the full game series
Hy 2013 Paul Tagliamonte A lisp with tight integration with Python
Ikarus 2007 Abdulaziz Ghuloum Scheme dialect
Interlisp 1967 BBN Programming environment built around a version of Lisp language; development began in 1967 at Bolt, Beranek and Newman in Cambridge, Massachusetts as BBN LISP, which ran on PDP-10 machines running the TENEX operating system; when Danny Bobrow, Warren Teitelman, and Ronald Kaplan moved from BBN to Xerox PARC, it was renamed Interlisp
ISLISP 1997 WG16 Small core language to help bridge the gap between differing Lisp dialects
Janet 2017 Calvin Rose Lisp-like programming language designed for system scripting and embedding within other programs, particularly those written in C or C++
Le Lisp 1981 INRIA Designed by Jérôme Chailloux, Emmanuel St. James, INRIA
Lisp Flavored Erlang (LFE) 2008 Robert Virding Lisp dialect built on Core Erlang and the Erlang virtual machine BEAM
Lisp Machine Lisp 1984 Sometimes named Zetalisp, is a direct descendant of Maclisp; was developed in the mid to late 1970s as the systems programming language for the MIT Lisp machines
Lispkit Lisp 1980 Peter Henderson A lexically scoped, purely functional subset of Lisp ("Pure Lisp") developed as a testbed for functional programming concepts.
Maclisp 1966 Project MAC Originated at MIT's Project MAC in late 1960s; based on Lisp 1.5; Richard Greenblatt was main developer of original codebase for the PDP-6; Jon L. White was responsible for later maintenance and development
MultiLisp 1980s Robert H. Halstead Scheme dialect, extended with constructs for parallel computing, executing, and shared memory; also had some unusual garbage collection and task scheduling algorithms
NIL 1970s MIT 32-bit Lisp implementation developed at MIT; intended as successor to Maclisp; NIL stood for New Implementation of LISP, and was in part a response to DECs VAX computer
OpenLisp 1988 Christian Jullien ISLISP compatible language with many Common Lisp extensions; runs on most modern operating systems
Owl Lisp 2012 Aki Helin Pure functional Scheme dialect; based on applicable subset of the R7RS standard; has been extended mainly with threads and the data structures needed for purely functional operation
PicoLisp 1988 Alexander Burger Open-source Lisp dialect; runs on Linux and other POSIX-compliant systems; most prominent features are simplicity and minimalism
Portable Standard Lisp 1980 University of Utah Tail-recursive dynamically bound Lisp dialect inspired by its predecessor, Standard Lisp and the Portable Lisp Compiler; it implements the Reduce computer algebra system
Racket 1994 PLT Inc. General purpose, multi-paradigm programming language in the Lisp-Scheme family; one of its design goals is to serve as a platform for language creation, design, and implementation; it is used in many contexts such as scripting, general-purpose programming, computer science education, and research
Scheme 1975 Guy L. Steele,
Gerald Sussman
Functional programming language with a minimalist design philosophy specifying a small standard core with powerful tools for language extension
