Here is a list of known Python-based WikiEngines

• Hatta -- a Wiki which runs out of a Mercurial repository whose pages are just the files in that repository

• Markdoc -- a lightweight Markdown-based Wiki system, public domain

• MoinMoin -- an evolution over PikiPiki that you're using now - multiple ways to run, plugin-based architecture with lots of plugins and large community, GPL

• MonkeyWiki -- another PikiPiki fork that claims to be simple to install/use, single file, very flexible templating, rewrite-friendly

• PikiPiki -- Python-based, will run completely standalone

• Pwyky -- WyPy's big brother, by the same author.

• PyleWiki -- Python-based, optional CVS backend, Unix-like rwxrwxrwx permissions on pages

• PyWiki -- Python-based, uses RCS, GPL license (development stalled)

• Sliki -- runs with ModPython

• Sphene Community Tools -- Django based wiki and forum applications.

• Sycamore -- seems to have roots in MoinMoin, but looks a little slicker while not as full featured. Uses a Postgesql or MySQL backend. GPL

• Trac -- an enhanced wiki and issue tracking system for software development projects. Supports MoinMoin-style, ReStructuredText, html, and textile as markup formats. Runs as cgi, FastCGI, ModPython, or with standalone server. Pluggable architecture with focus on simplicity.

• WikiForNow -- an old ZwiKi variant; used at zope.org; was meant to get a number of improvements implemented quickly, but has not evolved with usage patterns

• WikiNehesa -- Many features, including images, headerbars, TEXT centering, image inventory/previewer, image uploader. Modular. $FREE$. GNU GPL.

• WyPy -- a ShortestWikiContest contender, 23-, 18-, and 11-line versions.

• zim-wiki at http://www.zim-wiki.org -- WYSIWIG personal/desktop wiki with index, links, image inclusion, checkboxes and bulleted lists, equations, graphviz; calendar, ToDo; prints to clean html. Customizable, all-python over gtk2, inbuilt-server, uses filesystem as db; debian packaged. Documentation. Actively developed 2012.

• ZwiKi -- based in ZoPe, powerful, GPL.

Archaeology (dead, missing and outdated)

• CyberPublishing -- a wiki-based web publishing framework written in Python; GPL

• Luminotes -- a WYSIWYG personal wiki notebook for organizing your notes and ideas. Not currently developed.

• mojibake -- based on Sakana, runs with ModPython

• Not-Yet-Named Wiki -- runs on Webware. Supports static publishing, WYSIWYG editing, ReStructuredText

• http://moinmo.in/PikiePikie -- Python-based, lets you put a WebLog on any page (based on PikiPiki)
