LionWiki is a minimalist Wiki engine programmed in PHP. It is extensible, templatable, file based (it doesn't need database like MySQL) and requires just one file to function. It is suitable for small websites, personal notebooks or journals.

This project is dead and not recommended for use in new projects.

LionWiki provides essential Wiki functionality like Wiki syntax, page history, last changes, renaming pages, password protection (both read and write) etc. More features are provided by plugins.


Current version of LionWiki is 3.2.12. You can choose from two downloads:

  • Full featured LionWiki consisting of core file, templates, configuration file, language files and plugins.
  • Core LionWiki consisting of just one file which contains everything needed for basic functions. It is exactly the same as index.php from full featured LionWiki.

The only software requirement is PHP installation. See page on installation for details.


LionWiki is considered to be finished and is not developed anymore. If you have some question or suggestion, you can write me to

Disclaimer for developers(Edit)

LionWiki was designed from the beginning to be very small and simple. It's architecture is trivial which means that its core is quite hard to extend. It's also not suitable for studying purposes - there are a lot of examples of generally bad programming practices and PHP hacks which were used solely for the sake of small file size.
