In their own words
PmWiki
PmWiki is a wiki-based content-management system for collaboratively building and maintaining websites. Contributors can add and edit pages through the web without knowing HTML or CSS. Administrators can set password controls for an entire site, page groups, or individual pages, covering reading, editing, and uploads. Its access controls can work with existing password databases such as.htaccess, LDAP, and MySQL. Pages are stored as flat files, so a database is not required; the project says it can handle thousands of pages. Administrators can alter appearance and functions with skins, HTML templates, and extensions called recipes. Page histories include restore links, and the number of history days and revisions can be configured. PmWiki is free, open-source software for self-hosting that requires PHP. The listed plan is free. Project support resources include a FAQ, troubleshooting guide, error-message descriptions, and mailing lists. Maintainer Petko Yotov offers paid technical support and development at €60, paid once, billed at 60€ / hour, with an invoice provided. The release notes list version 2.7.6, dated 2026-09-18, with updates for recent PHP versions; version 2.7.5 closed a Windows-server vulnerability under specified conditions.
