ikiwiki is a free and open-source wiki application, designed by Joey Hess.

ikiwiki is written in Perl, although external plugins can be implemented in any language.

Unlike conventional wiki software, ikiwiki stores its pages in a standard version control system such as Git, Subversion or others.

[2] ikiwiki supports several lightweight markup languages, including Markdown, Creole, reStructuredText and Textile.

In the simplest case, it can function as an off-line static web site generator (possibly still allowing different users to submit changes through VCS; this method is sometimes referred to as wiki compiler), but it can use CGI to function as a normal web-interfaced wiki as well.
