Serendipity is a blog and web-based content management system written in PHP and available under a BSD license. It supports PostgreSQL, MySQL, SQLite database backends, the Smarty template engine, and a plugin architecture for user contributed modifications. [2]

Serendipity is available through a number of "one-click install" services such as Installatron.[3]


Serendipity's plugin architecture allows users to easily modify both the appearance of the blog and its features.

Serendipity's SPARTACUS plugin automatically checks the central repository for plugins/templates upgrades and new functionality whenever a user checks the list. Users can install more than 120 plugins, instantly enhancing their blogs' functionality. [4]

The Serendipity project was started by Jannis Hermanns in the winter of 2002, then still called jBlog. Due to a naming conflict with an existing blog publishing system, Sterling Hughes suggested the name serendipity. This suggestion is based on an Essay by Sam Ruby. The short form s9y stems from abbreviations such as i18n for internationalization where the number represents the amount of omitted letters. Today the project is maintained by Garvin Hicking.
