What is Gibbon?

Gibbon is a free, open-source school management system that focuses on the educational process, classes management, and the primary educational audience, the "students".

Gibbon was founded in October 2010 in response to a lack of powerful, usable and open source school platforms. Right from the beginning, Gibbon was designed to be flexible, extensible and themeable, whilst aiming to help teachers to do their jobs.

It is built on top of PHP, MySQL, jQuery, HTML5 and several other technologies.
