#1
Core Functionality
Joomla! includes advanced tools in its core installation, so you can build a complete site without adding extensions for the basics.
Multilingual Support
Create multilingual websites out of the box, with no third-party extension required.
Granular Permissions
Joomla!’s Access Control Lists (ACL) let you control exactly who can view, edit or publish specific pieces of content.
User Groups
Create unlimited custom user groups and hierarchical access levels, ideal for intranets, membership sites and complex corporate portals.
#2
Content Flexibility
Organize large amounts of content and shape every page the way you want, with ease.
Flexible Layouts
Joomla! does not lock you into a rigid “post versus page” structure. Its menu system lets you assign different layouts, templates and modules to specific pages.
Nested Categories
Build an unlimited hierarchy of categories and subcategories, which makes it a natural fit for sites with a lot of content.
Custom Fields
Add custom data fields to your articles, users or contacts directly from the dashboard.
#3
Ease of Use
Joomla! is designed so authors and site owners can manage a site with confidence, without writing code.
Familiar Editing Experience
A built-in visual (WYSIWYG) editor and a Media Manager let authors write, format and manage images and files without touching code.
Content Versioning
Keep a history of changes to your articles and other content, and restore a previous version whenever you need it.
Smart Search
Core indexing, filtering and auto-suggest help your visitors find what they are looking for.
#4
Accessibility
Joomla! is built for everyone. Accessibility is part of the foundation of the CMS, not an afterthought, helping you build websites that are usable by all.
Built-In Tools
An Accessibility Checker flags issues and guides authors toward WCAG compliance. A “skip-to-content” plugin serves keyboard and screen reader users. An accessibility toolbar adds options such as a reading guide, text-to-speech and display adjustments.
Funded by the Sovereign Tech Fund
Open Source Matters has received funding from the Sovereign Tech Fund for an ongoing development program, with the ambition of making Joomla! the most accessible CMS in the world.
Evolving Standards
As web accessibility regulations tighten for businesses and the public sector, Joomla!’s core evolves alongside current standards to help keep your site on track.
#5
Security & Reliability
Joomla! takes a proactive approach to data safety and site uptime, with protection built into the core.
Built-In Security Features
Native two-factor authentication (2FA), strong encryption standards and strict security protocols are part of the core code.
TUF-Secured Core Updates
Joomla! can install core updates, bug fixes and patches automatically in the background, so you don’t have to update manually. The process is protected by The Update Framework (TUF), which verifies the authenticity of every file and helps prevent malicious code from being delivered through a fake update.
Frequent Patches
A dedicated security team monitors threats and releases core updates quickly to close security gaps.
#6
Privacy & Compliance
Protecting your users’ data shouldn’t require complex configuration. Joomla!’s native Privacy Tool Suite helps you meet data protection laws such as the GDPR.
Consent Management
Collect and track user consent to your privacy policy and terms of service during registration or form submissions.
Data Export & Deletion
Handle “right to be forgotten” requests: administrators can export or anonymize a user’s personal data in a few clicks.
Privacy Dashboard
Monitor data requests, check capabilities and keep a clear audit trail from the administrator control panel.
#7
SEO & Performance
Joomla! includes search engine optimisation tools in its core, so your site is ready to be found from day one.
Metadata, SEF URLs & Redirects
Manage meta titles, descriptions and robots tags for any page from the dashboard. Search Engine Friendly (SEF) URLs are generated without third-party extensions, and built-in redirect tools make site migrations and link updates easier to handle.
Structured Content & Schema Support
Implement rich snippets and microdata, and format your data so search engines can crawl, understand and index your content more effectively.
Speed Optimisation
Native caching and GZIP compression help your pages load quickly, which search engines and visitors both appreciate.
#8
Automation & Web Services
Joomla! includes automation tools that help teams streamline editorial processes and securely connect their website to other applications.
Custom Publishing Workflows
Design step-by-step review stages for your content, for example from Draft to Needs Review, Approved and finally Published. Team members can be notified automatically when it is their turn to review or edit.
Scheduled Tasks
Automate routine maintenance from the dashboard, such as clearing cache files, checking for broken links or importing data feeds at set times, without complex server setups.
Web Services API
A comprehensive native API lets other software securely communicate with your website, making it easier to sync your content with mobile apps, customer databases (CRMs) or inventory systems.
#9
Developer-Friendly
Joomla! has a structured architecture that gives developers full control over layout and functionality, without compromising your site’s stability.
MVC Architecture
Built on a clean Model-View-Controller framework, Joomla! separates your data from how it is displayed. PHP developers can write clean, override-friendly code and change layouts extensively without breaking the core during future updates.
Child Templates and Overrides
Child templates inherit styles from a parent template, so you can customize the look and feel of specific pages without changing core files. Your custom designs survive system updates.
Extension Ecosystem
Because so much is built in, Joomla! needs fewer extensions, but thousands of components, modules and plugins are available in the Joomla! Extensions Directory when you want to go further.
