"Wiki" is a class of collaborative hypertext authoring systems. Inspired by Ward Cunningham's WikiWikiWeb, many wiki sites and software systems now exist in a variety of languages.

There are several wiki systems that have been built in Common Lisp:

  • ALIW - A Lisp in Wonderland (a.k.a `ALIW') is a wiki software written in Common Lisp, to ease the collaboration on editable web pages
  • CLiki - CLiki is the Common Lisp wiki, a community resource about various topics pertaining to the Common Lisp programming language, as well as a directory of Free Software Common Lisp libraries, implementations, and applications
  • The Old Cliki - This is a page about the old version of the wiki software that used to run
  • XL-Wiki - XL-Wiki is a fork of CL-Wiki that aims to allow applications to modify and extend its functionality in interesting ways
