MediaWiki vs PmWiki

MediaWiki is free, server-based wiki software for collecting, organizing, and sharing knowledge. Contributors edit pages in wikitext without needing HTML or CSS, and previous page versions remain available for reverting. Administrators can customize appearance and behavior with extensions; caching supports large, high-traffic wikis. Its REST API provides HTTP access to wiki content and functions such as search, page transformations, and history, with JSON or HTML output and extension-specific endpoints. MediaWiki is self-hosted under GNU GPL version 2 or later and is provided without warranty to the extent permitted by law. The latest stable version requires PHP 8.3.0 or later, a web server, and MariaDB 10.3.0+, MySQL 5.7.0+, PostgreSQL 10.0+, or SQLite 3.31.0+. Each release receives security updates for one year, and developers recommend subscribing to the low-traffic mediawiki-announce list. Third-party extensions may be unmaintained, vulnerable, incompatible with some versions, or unreliable together. Documentation, FAQs, community channels, and a support desk are available through the MediaWiki site.

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.
