DokuWiki

DokuWiki is an open source wiki engine for building documentation sites, team knowledge bases, and other shared reference pages. It stores content as plain text, which makes the wiki easy to maintain and keeps page data outside any database.

It runs on PHP and focuses on simple editing and clear page organization. Content lives in pages grouped into namespaces, with revision history for tracking changes. Access control and authentication connectors govern who can read and edit, and a plugin system extends the engine's behavior.

Keeping pages in plain files means version control, backups, and external tooling all work directly against the data, with no export step. The engine has been developed since 2004 by Andreas Gohr and the DokuWiki Community.
