Chyrp is a free and open source blog publishing application, developed by Alex Suraci. Chyrp is intended to be light-weight, yet functional.[1]


The idea of Chyrp has started in 2004 by Alex Suraci. Initially the project was called MCMS (mynimal CMS); then Mynimalistic; then Lingua; and so it has derived to Chyrp.

In 2009 development stopped, and in May 2010 Suraci announced the death of the project due to a lack of contributors.[2] However, in November Chyrp user Arian volunteered to take over development, and work resumed on a part-time basis.[3]

In October, 2012 an anonymous benefactor enabled Chyrp's lead developer to work full-time on Chyrp,[4] leading to a more methodical development approach. Chyrp 2.5b3 contained a new WYSIWYG editor, RedactorJS, which was purchased by the Chyrp project a month prior.


Chyrp is a tumblelog-like blogging engine,[5] hosted on one's own server. It is based on the Model View Controller paradigm, and the view layer uses a flexible plug-in system, with modules called "Feathers", providing support for different types of content. Like most blogging engines, Chyrp supports themes which can change the appearance of the website.

Chyrp is built over PHP, MySQL (or SQLite), and AJAX[6]

Core modules[edit]

The default Chyrp install is rather vanilla, but Chyrp can be extended through modules. Modules are things that enable extra functionality to Chyrp. There are sixteen default Modules bundled to every Chyrp installation, each providing certain functionality for a certain topic.
