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.


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[edit]

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 1.3.7 was released on 13 May 2016.[4]

Wikka features[edit]

Among the distinctive features of this wiki engine:

  • Support for different types of embedded elements:
  • Advanced access control with user registration, password management, and provision for user profiles, as well as access control lists on a per-page basis.
  • Administration modules to manage pages and users, including tools for bulk operations like user removal or page reversion.
  • Advanced syntax highlighting using GeSHi:
    • support for 68 markup/programming languages
    • easily customizable output
    • line numbering
    • clickable markup pointers to official documentation
    • on-the-fly downloading of embedded code blocks
  • Several page-related features, including full revision control, comments, categories, text searching, page cloning, advanced referrer management, file uploading/downloading interface, and a GUI page editor.
  • W3C compliant XHTML 1.0 transitional and CSS.
  • Theme support
  • CSS-defined printable view.
  • Advanced tools for publishing page revisions, including:
  • RSS feeds for recent modifications and page revisions (with autodiscovery)
  • WikiPing client functionality, allowing page changes to be broadcast and tracked on a remote WikiPing server
  • SmartTitle function, generating human- and search-engine-friendly page titles.
  • A web-based wizard to install the package and to upgrade from WakkaWiki.
  • A large repository of user-contributed plugins.
  • A table of contents generator that creates a linked list of headings on a page, useful for navigating very long pages.


A dedicated server provides extensive documentation and tutorials, targeted at different categories of users, from the end user to the developer.[5]
