Awesome Common Lisp Application Software


Lisp logo

This is a list of awesome application software built with Common Lisp.

We want to keep the 'master' list curated. If you want to uncurated list, see complete list branch.

Table of Contents



  • OpusModus - a comprehensive computer-aided environment for the whole work of music composition. Proprietary.
  • OM7 - a new implementation of the OpenMusic visual programming and computer-aided composition environment including a number of improvements on graphical interface, computational mode, and connection to external software libraries. [GPL3][2].
  • Common Music - the repository of an ancient version of Common Music (version 2.12.0), the presumably last version which ran on Common Lisp dating from around 2007-09, before work on Common Music shifted to (scheme-based) cm3.
  • Incudine - Music/DSP programming environment for Common Lisp. Useful to design software synthesizers or sound plugins from scratch. It is also a compositional tool that allows to produce high quality sounds controllable at the sample level, defining and redefining the digital signal processors and the musical structures on-the-fly.
  • Shuffletron - a search-based music player for the terminal. MIT-style licence.
  • Ernestine - Ernestine is a music management application in McClim. MIT.
  • CLM - Common Lisp Music is a music synthesis and signal processing package in the Music V family. It provides much the same functionality as Stk, Csound, SuperCollider, PD, CMix, cmusic, and Arctic — a collection of functions that create and manipulate sounds, aimed primarily at composers (in CLM's case anyway).
  • Open Music - a visual programming, computer-aided composition environment. [GPL3][2].

Other Lists


Thanks to All of Github contributors and Everyone @ ad r/Common_Lisp/ for many suggestions and compliments.

Guidelines to contribute

Please follow this format of the list [Appname](#link) - description. [License]. if you want to make a contribution.

  • Put the name of the application and link to its homepage in the list.
  • Write a short description for the application.
  • Add a license in the end of the list. see the list format above
  • Make sure it is put under the appropriate topic.
  • If the application doesn't fit in any existing topic, make a new one for it.
  • Sort the item by its popularity.
    • we come up with this approach since alphabetically sorted make people unnoticed which app has more active development and which app unmaintained or abandoned.

Unsure how to contribute?


  • You can learn about licenses in tl;drLegal
  • There are so many Applications buit with Lisp, but most of them are more than 20 years old, this list will be endless as Rainer Joswig said, so here I wil only include the relevant application.
