Introduction: What Is Joomla?

Joomla is a free and open-source content management system (CMS) used to build, manage, and publish websites, blogs, and online applications. Launched in 2005 as a fork of Mambo, Joomla has grown into one of the world’s most trusted CMS platforms, powering over 2 million websites globally as of 2025.

Unlike website builders like Wix or Squarespace, Joomla provides more control, flexibility, and scalability, making it ideal for developers, designers, and advanced users who want to build customizable and feature-rich websites.

Why Joomla Still Matters in 2025

In an era dominated by WordPress, no-code builders, and proprietary SaaS tools, Joomla continues to have a dedicated user base. It’s particularly valued for:

  • High-level user control and permission management
  • Robust multilingual support (out of the box)
  • Flexible template and module system
  • Extensive extension library (over 6,000 extensions)
  • Security-first architecture

If you’re looking to build a scalable, secure, and customizable site without being locked into proprietary platforms, Joomla remains a powerful contender.

How Does Joomla Work?

Joomla operates as a self-hosted CMS, meaning you need to download the software and install it on your own web server. Once set up, it provides a backend interface for content creation, layout control, and website administration.

Here’s how the process typically works:

1. Installation

You can install Joomla in one of two ways:

  • Manual Installation: Download from joomla.org and install it via FTP and a MySQL database.
  • One-Click Install: Many hosting providers (like SiteGround or Hostinger) offer 1-click Joomla installs via cPanel or Plesk.

2. Administrator Dashboard

The backend (admin panel) is where most of the site management happens:

  • Create and organize content
  • Manage users and permissions
  • Install extensions
  • Configure global settings

3. Templates and Modules

Joomla separates content and design:

  • Templates define how your site looks.
  • Modules display different types of content (menus, sliders, ads, etc.)
    You can assign different templates or modules to specific pages for precise control.

4. Content Creation

Joomla uses Articles as its primary content type. These can be categorized and displayed using:

  • Menus
  • Categories
  • Modules

It supports rich text formatting, image embedding, and media management.

5. Extensions and Plugins

Joomla’s capabilities can be expanded with:

  • Components (e.g., forums, shopping carts)
  • Modules (frontend widgets)
  • Plugins (background functionality like caching or spam control)
