If you've been managing Joomla sites for any length of time, you've probably felt that familiar pit in your stomach when a major version drops. Joomla 4 was rough. Joomla 5 smoothed some edges. But Joomla 6? It's shaping up to be the most divisive release in the CMS's history. The admin panel UX has been overhauled, the extension manager is fundamentally different, template rendering has breaking changes that affect nearly every custom template, and the community is... not handling it well.

I've been building and maintaining Joomla sites since the Mambo days. I've migrated clients through every painful major version bump. So when I say Joomla 6 feels different — not in a good way — I'm not being dramatic. Let me walk you through exactly what's changed, why long-time admins are upset, and what realistic alternatives exist if you're considering jumping ship.

Why Joomla Admins Are Furious About Joomla 6 UX Changes

The Joomla 6 Admin Panel UX Overhaul

Let's start with the most visible change: the admin panel. Joomla 6 introduces what the development team calls a "modern administrative experience." In practice, this means they've ripped out the familiar left-sidebar navigation that Joomla admins have used since Joomla 4 and replaced it with a top-nav plus contextual sidebar approach.

What Actually Changed

The old admin panel had a collapsible left sidebar with nested menu items. You could get to any section of the CMS in two clicks, maximum. It wasn't pretty, but it was functional and — crucially — it was consistent.

Joomla 6 moves to a horizontal top navigation bar with dropdown mega-menus. The left sidebar now only appears contextually, showing options relevant to the section you're currently in. Article management, user management, extension configuration — they all have different sidebar layouts now.

Here's a comparison of the navigation patterns:

Action Joomla 5 (clicks) Joomla 6 (clicks) Notes
Create new article 2 2-3 Depends on current context
Access Global Configuration 2 3 Buried under System menu
Manage extensions 2 2-4 New categorized view adds steps
Edit template files 3 4-5 Template editor relocated
Check system info 2 3 Moved to sub-menu
Manage media files 2 2 Roughly equivalent

Why Admins Hate It

The core complaint isn't that it looks different. Admins can adapt to visual changes. The problem is that muscle memory — the thing that makes daily CMS management bearable — is completely broken.

When you manage 15+ Joomla sites and you're switching between them throughout the day, you rely on knowing exactly where things are without thinking. Joomla 6 forces you to re-learn everything. And the contextual sidebar means the navigation isn't even consistent within the new system. The sidebar shows different items depending on where you are, which makes building new muscle memory harder.

There's also the accessibility angle. Several community members have reported that the mega-menu dropdowns don't work well with screen readers, and keyboard navigation is inconsistent. For an open-source CMS that prides itself on accessibility, this is a significant regression.

The Dashboard Widgets Problem

Joomla 6 also introduces a new dashboard widget system that replaces the previous dashboard modules. The old system let you add and arrange dashboard modules with reasonable flexibility. The new widget system is more visually appealing but significantly less configurable.

You can't create custom dashboard layouts per user group anymore — a feature that many Joomla agencies used to create simplified admin experiences for clients. Instead, there's a single dashboard layout with role-based visibility toggles on individual widgets. It's a step backward in functionality dressed up as a step forward in design.

Extension Manager: Everything You Knew Is Wrong

This is where things get truly painful. Joomla 6 introduces a completely rewritten extension management system, and it breaks compatibility with how extensions have been packaged and installed for over a decade.

The New Extension Architecture

Joomla 6 moves to a Composer-based extension management system. On paper, this is a good idea. Composer is the standard for PHP dependency management, and bringing Joomla in line with modern PHP practices makes sense.

In practice, it means:

  • Extension packages must now include a composer.json with proper namespace declarations
  • The old XML manifest format is deprecated (still works in 6.0 but throws warnings, scheduled for removal in 6.2)
  • Extension discovery and installation paths have changed — custom installation scripts that reference old paths will break
  • The update server protocol has been revised — extensions using the old update XML format need to migrate to the new JSON-based update manifest
// New Joomla 6 extension manifest (composer.json excerpt)
{
  "name": "vendor/my-joomla-extension",
  "type": "joomla-plugin",
  "require": {
    "joomla/cms": "^6.0"
  },
  "extra": {
    "joomla": {
      "element": "myextension",
      "group": "content",
      "namespace": "Vendor\\Plugin\\Content\\MyExtension"
    }
  }
}

The Extension Compatibility Crisis

Here's the real-world impact: a significant portion of the Joomla extension ecosystem isn't ready. According to data from the Joomla Extensions Directory (JED) as of early 2025, roughly 40% of listed extensions haven't been updated for Joomla 5 compatibility, let alone Joomla 6.

Of the extensions that are Joomla 5 compatible, early testing suggests around 60-70% will need non-trivial modifications to work with Joomla 6's new extension architecture. We're not talking about minor tweaks. We're talking about restructuring how extensions are packaged and distributed.

For popular extensions like Akeeba Backup, RSForm, and JCE Editor, the developers have already announced Joomla 6 compatible versions are in development. But for the thousands of smaller extensions maintained by solo developers or small teams? Many of those will simply be abandoned.

What This Means for Site Owners

If your Joomla site depends on five or more third-party extensions (and most do), you need to audit every single one before even thinking about upgrading. Create a spreadsheet. Check each extension's developer site for Joomla 6 announcements. If there's no mention of Joomla 6 support, assume it won't work.

I've done this audit for three client sites so far. Two of them have at least one critical extension with no Joomla 6 roadmap. That's a migration blocker.

Template Rendering Breaking Changes

The template system changes in Joomla 6 are the kind of thing that makes experienced developers wince. Joomla has moved from its traditional PHP-based template override system to a hybrid approach that introduces a new templating layer.

The New Template Engine

Joomla 6 introduces Twig as an optional (but clearly preferred) template engine alongside the traditional PHP overrides. The core admin templates are now written in Twig. Frontend templates can use either PHP or Twig, but the template override discovery system has changed.

{# Joomla 6 Twig template example #}
{% extends "@joomla/base.html.twig" %}

{% block content %}
  <div class="com-content-article">
    <h1>{{ article.title | escape }}</h1>
    <div class="article-body">
      {{ article.introtext | raw }}
      {{ article.fulltext | raw }}
    </div>
  </div>
{% endblock %}

What Breaks

The override discovery order has changed. In Joomla 5, template overrides lived in templates/your-template/html/com_content/article/default.php. This still works in Joomla 6, but if a Twig version exists at templates/your-template/html/com_content/article/default.html.twig, the Twig version takes priority.

This means that if a template developer ships both PHP and Twig overrides (which many will to support the transition), your custom PHP overrides might get silently ignored. I've already seen this bite people in beta testing.

Additionally, the template parameters system has been reworked. Template parameters defined in templateDetails.xml now need corresponding entries in a new template.config.php file. Old parameters still load, but new features like live preview and the visual template configurator only work with the new format.

Impact on Commercial Templates

Commercial template providers like JoomlArt, GavickPro, and Youjoomla are in a difficult position. Their business model relies on maintaining template frameworks that work across Joomla versions. The Twig introduction and override priority changes mean they essentially need to rebuild their template frameworks.

Some have announced they'll skip Joomla 6 support entirely and focus on their own page builder tools or transition to other platforms. That's a telling signal about how the template community views these changes.

Why Joomla Admins Are Furious About Joomla 6 UX Changes - architecture

Community Reaction: Forums, GitHub, and Social Media

The community response has been... intense. And mostly negative.

GitHub Issues and Pull Requests

The Joomla GitHub repository has seen a spike in issue reports tagged with the J6 milestone. Several high-profile community members have opened detailed issues documenting UX regressions. One particularly notable thread, with over 200 comments, argues that the admin panel changes were pushed through without adequate community consultation.

The pull request that introduced the new extension manager architecture received significant pushback during review, with several long-time contributors voting against the merge. It was merged anyway, with the production leadership team citing the need to modernize the codebase.

Forum Sentiment

The Joomla Community Forum and the unofficial Joomla subreddit have been overwhelmed with posts from frustrated administrators. Common themes include:

  • "Why fix what wasn't broken?" — The admin panel UX, while not perfect, was functional and familiar
  • "Extension apocalypse" — Fears that the Composer-based system will kill the extension ecosystem
  • "Who asked for Twig?" — Template developers feeling blindsided by the templating engine change
  • "Where's the migration path?" — Lack of clear, automated migration tools for existing sites

The Broader Context

This isn't happening in a vacuum. Joomla's market share has been declining steadily. According to W3Techs data from 2025, Joomla powers roughly 1.5% of all websites with a known CMS, down from 2.6% in 2022. WordPress sits at over 62%. Every controversial decision accelerates the migration of sites away from the platform.

The community frustration isn't just about Joomla 6 specifically. It's the accumulation of years of feeling like the project leadership doesn't listen to the people who actually use the software daily. Joomla 6 is the catalyst, but the resentment has been building.

What the Joomla Leadership Is Saying

The Open Source Matters (OSM) board and Joomla production leadership have responded to the criticism, though many feel the responses have been tone-deaf.

The official position is that these changes are necessary for Joomla's long-term survival. The Composer-based extension system brings Joomla in line with modern PHP development practices. The Twig templating layer makes the platform more accessible to developers coming from other frameworks. The admin UX changes are based on user research (though the research methodology and sample size have been questioned).

A blog post from the Joomla production department in early 2025 acknowledged the transition pain but argued that short-term disruption is necessary for long-term viability. The post drew comparisons to the Joomla 1.5 to 2.5 transition, which was also painful but ultimately moved the platform forward.

The comparison is apt, but not in the way they intend. The 1.5 to 2.5 transition drove away a massive portion of the community. Many of those users never came back.

Should You Migrate or Should You Leave?

This is the question everyone's asking, and the honest answer depends on your specific situation.

Stay If...

  • Your site uses mostly core Joomla functionality without heavy extension dependencies
  • Your template is based on Cassiopeia or a framework that's committed to Joomla 6 support
  • You have in-house PHP developers who can handle the migration work
  • Your organization is committed to Joomla for political/institutional reasons

Leave If...

  • Your site depends on extensions that don't have a Joomla 6 roadmap
  • You're already frustrated with Joomla and this is the last straw
  • You need a platform with a growing (not shrinking) ecosystem
  • The cost of migrating to another CMS is comparable to the cost of upgrading to Joomla 6

The Cost Reality

Here's something people don't talk about enough: migrating from Joomla 5 to Joomla 6 may cost almost as much as migrating to a different CMS entirely. If you need to rebuild templates, update extensions, retrain staff, and test everything, you're looking at significant development hours regardless of the target platform.

For a medium-complexity Joomla site (50-200 articles, 5-10 extensions, custom template), you're probably looking at 40-80 hours of migration work to Joomla 6. A migration to a headless CMS setup with a modern frontend? 60-120 hours. The gap isn't as large as you'd think, and the headless approach gives you a platform with a growing ecosystem instead of a shrinking one.

Realistic Alternatives to Joomla in 2025

If you're seriously considering alternatives, here's an honest assessment of the options.

Platform Best For Learning Curve Ecosystem Size Long-term Trajectory
WordPress Content-heavy sites, blogging Low Massive Stable but Gutenberg divisive
Headless CMS + Next.js Performance-critical sites, apps Medium-High Growing fast Strong upward
Headless CMS + Astro Content sites, marketing sites Medium Growing Strong upward
Drupal Enterprise, government, complex data High Large Stable
Craft CMS Mid-size content sites Medium Moderate Stable
Statamic Laravel shops, content sites Medium Growing Positive

The Headless CMS Approach

I'm biased here because this is what we do at Social Animal, but the headless CMS approach solves the fundamental problem that keeps recurring with traditional CMSs like Joomla: the coupling of content management with frontend rendering.

When your CMS is headless, admin UX changes in the CMS don't break your frontend. Template rendering is handled by your frontend framework (Next.js, Astro, whatever), not the CMS. And your content is accessible via APIs, meaning you're never locked into a single rendering technology.

If you're interested in this approach, we've done quite a few Joomla-to-headless migrations. Our headless CMS development work pairs well with either Next.js or Astro on the frontend, depending on your needs.

WordPress: The Obvious Choice?

WordPress is the default suggestion whenever someone asks about Joomla alternatives, and it's not wrong. The ecosystem is enormous, hosting options are plentiful, and most web developers know it.

But WordPress has its own UX controversies (the block editor/Gutenberg saga mirrors some of what's happening with Joomla 6). And WordPress's market dominance makes it the biggest target for attacks. If you're leaving Joomla because of governance concerns, WordPress's current Matt Mullenweg situation might give you pause too.

Drupal: The Power User's Choice

Drupal is worth considering if your Joomla site has complex content relationships, custom content types, or enterprise requirements. Drupal 11 is solid, and the Drupal community is more stable (if smaller) than Joomla's.

The downside: Drupal's learning curve is steep, and development costs are typically higher than Joomla or WordPress.

Migration Strategies That Actually Work

If you've decided to leave Joomla, here's how to approach the migration without losing your mind or your SEO rankings.

Step 1: Content Audit

Export everything. Joomla's database structure is well-documented, and you can pull content directly from the #__content, #__categories, #__menu, and #__users tables. Don't rely on Joomla's built-in export tools — they're limited. Write custom SQL queries or use a tool like Akeeba's data export functionality.

Step 2: URL Mapping

This is the step everyone skips, and it's the one that destroys your SEO. Create a complete map of every URL on your Joomla site and its corresponding URL on the new platform. Set up 301 redirects for every single one.

# Example: generating a URL list from Joomla's database
mysql -u root -p joomla_db -e "
  SELECT CONCAT('/', alias) as url, title
  FROM j_content
  WHERE state = 1
  ORDER BY id;
" > joomla_urls.csv

Step 3: Choose Your Target Architecture

Decide whether you want another traditional CMS or a headless setup. If your site is primarily content-driven (articles, blog posts, documentation), a headless CMS with a static-first frontend framework like Astro will give you dramatically better performance.

Step 4: Migrate in Parallel

Don't try to do a big-bang migration. Set up the new site alongside the old one. Migrate content in batches. Test thoroughly. Only switch DNS when you're confident everything works.

FAQ

When is Joomla 6 officially releasing? Joomla 6 is targeting a stable release in late 2025, following the project's new time-based release cycle. Alpha and beta versions are already available for testing. The release timeline has slipped a couple of times already, so the exact date remains fluid.

Will my Joomla 5 extensions work in Joomla 6? Most won't work without modifications. Joomla 6's Composer-based extension system requires new manifest formats and updated namespace declarations. Extensions that rely on deprecated APIs or old installation paths will break. Check with each extension developer for their Joomla 6 compatibility roadmap before attempting an upgrade.

Can I stay on Joomla 5 instead of upgrading? Yes, for now. Joomla 5 will receive security updates until approximately 2 years after the Joomla 6 stable release, which means roughly late 2027. After that, you're on your own. Staying on an unsupported CMS version is a significant security risk, so this is a temporary solution at best.

Is the Joomla community actually splitting over this? There's real tension, but it hasn't resulted in a formal fork (yet). Several prominent community members have publicly stepped back from contributing. The Joomla community has weathered internal conflicts before, but the combination of declining market share and controversial technical decisions makes this period feel more precarious than past disputes.

What's the cheapest way to migrate away from Joomla? The most cost-effective migration path depends on your site's complexity. For simple content sites with fewer than 100 pages, a manual migration to WordPress or a headless CMS can be done in 20-30 hours. For complex sites with custom extensions, expect 80-150+ hours. Using automated migration tools like CMS2CMS can reduce costs for straightforward content moves but won't handle custom functionality.

Should I wait for Joomla 6 to stabilize before judging it? That's fair advice for the UX changes — first impressions of new interfaces are often harsher than the settled opinion. But the architectural changes (Composer extensions, Twig templates) aren't going to change. Those are fundamental design decisions. If those are your concern, waiting won't help.

How does Joomla 6 compare to Drupal 11 for enterprise sites? Drupal 11 is generally a stronger choice for enterprise-grade websites with complex content models, granular permissions, and API-first requirements. Joomla 6's modernization efforts close some gaps, but Drupal's ecosystem for enterprise use cases (content workflows, multilingual support, headless delivery) is more mature. If you're already considering the migration effort, Drupal is worth evaluating.

What's the best headless CMS to replace Joomla? It depends on your team and requirements. For content-heavy marketing sites, Sanity or Contentful paired with Next.js or Astro are excellent choices. For sites that need more structure, Strapi or Payload CMS give you more control over your content models. The key advantage of any headless approach is that you're decoupled from the CMS's frontend rendering — meaning you'll never face this kind of template-breaking upgrade again.
