What It Is

Geeklog is an open-source PHP content management system that can also be used as a blog engine. It supports MySQL and PostgreSQL. The currently recommended production release is v2.2.2, with explicit support for PHP 8.1. The project has a long history—the main documentation notes that it has been developed since around 2001. Licensed under GNU GPLv2, Geeklog is positioned more like a traditional self-hosted CMS than a SaaS website builder or headless CMS.

Core Features and Developer Perspective

In terms of features, Geeklog provides out-of-the-box support for article creation, scheduling, drafts, multiple themes, multiple authors, user submissions, comments, Trackback, Pingback, RSS/RDF/Atom syndication formats, spam protection, calendars, links, polls, static pages, and sitemaps. Security is one of its key focuses: it includes user accounts, access control, a Unix-like object-level permission model, password encryption, admin access logs, error logs, and SQL query logs.

On the technical side, Geeklog is built with PHP and supports MySQL/PostgreSQL, making it suitable for LAMP/LEMP-style environments. Its extensibility is fairly complete, with a plugin API, theme development support, a configurable block system, php-in-block, a database abstraction layer, and built-in support related to jQuery, jQuery UI, and Uikit. In terms of ecosystem, community plugins cover forums, image galleries, Spam-X, Static Pages, XMLSitemap, reCAPTCHA, Ban, and more. Email sending has moved to PHPMailer, while authentication supports remote methods such as OpenID and OAuth.

Pricing and Documentation Support

The main materials do not show commercial pricing, a hosted edition, or enterprise support. What can be confirmed is that Geeklog is GPLv2 open source and can be downloaded and used for free. Documentation resources are relatively extensive, covering installation/upgrades, configuration, bundled plugins, APIs, plugin development, theme development, FAQ, Wiki, forums, bug reports, and feature request channels. However, the mailing list service was discontinued by its provider in 2026, and the archives were lost, which suggests some uncertainty around community support channels.

Pros, Cons, and Who It’s For

Geeklog’s strengths are its open-source transparency, self-hosting capability, and relatively complete permissions and security model. It is suitable for teams that need a traditional CMS, community site, blog portal, multi-author content site, or PHP-based plugin customization. Its drawbacks are that it feels more traditional, with no clear emphasis on modern visual site building, cloud hosting, or a headless API-first experience. Installation and maintenance also require experience with PHP, web servers, and databases. The source material does not provide information about accessibility from China, so network performance and payment availability cannot be assessed. Alternatives to compare include WordPress, Drupal, Joomla, Grav, and Ghost.
