WikkaWiki (often shortened as Wikka) is a free, lightweight, and standards-compliant wiki engine. Written in PHP, it uses MySQL to store pages. WikkaWiki is a fork of Wakka Wiki to which a number of new features have been added. It is designed for speed, fine-grained access control, extensibility, and security, and is released under the GNU General Public License.

  History

In 2003, the development of Wakka Wiki came abruptly to an end, although a large community of users and contributors were still posting bugfixes, extensions, and new functions. First released in May 2004 by Jason Tourtelotte, WikkaWiki rapidly grew into a project aiming to remain faithful to Wakka's heritage of a lightweight engine with readable and accessible code. It was the first wiki engine to introduce mindmapping support allowing users to collaboratively edit mindmaps via wiki pages,^[1][2] a feature largely adopted by the majority of other wikis thereafter.

  Wikka vision

Compared to heavier wiki engines, which integrate several built-in functions, WikkaWiki's goal is to keep its core as small as possible while developing an architecture that supports easy extensibility through plugin modules. Wikka's backend is based on a MySQL relational database, which makes it fast, reliable and more scalable than wiki engines based on flat text storage.^[3]

The latest version 1.3.3 was released on 20 May 2012.^[4]
