Joomla, the award-winning open-source CMS, is proud to celebrate its 20th anniversary on August 17, 2025.

To mark this milestone, Joomla is hosting a global celebration featuring a series of virtual events.

A Tribute to the Volunteers Behind the Code

Heart OUT

At the heart of Joomla's success lies its global network of passionate volunteers — from core developers and testers to documentation writers, designers, translators, moderators, and event organizers. For 20 years, this community-powered model has driven every major release, secured the platform, and fostered a culture of openness and mentorship.

This anniversary is a tribute to all the contributors — past and present — who have given their time, skill, and energy to make Joomla what it is today. Thank you for your code, your commitment, and your community spirit. Read more: https://20-years-of.joomla.org/volunteers
