What is Joomla?
Joomla is a mature open-source CMS that ships with powerful built-in features like multilingual support and hierarchical access control. It sits between WordPress's simplicity and Drupal's complexity. While technically capable, its declining market share and shrinking ecosystem make it a harder recommendation for new projects in 2026.
What is WordPress?
WordPress is the undisputed CMS market leader, powering 43%+ of all websites in 2026. Its strength is ecosystem scale—more plugins, more themes, more developers, and more hosting options than any competitor. While it relies on plugins for features some CMS platforms include natively, its low learning curve and extensibility make it the default choice for small business websites.
Key Differences
Market Share and Ecosystem Momentum
WordPress commands 60%+ of the CMS market with 43% of all websites. Joomla has dropped below 2% and is declining. This isn't just a vanity metric—it directly affects how many developers you can hire, how many hosting providers optimize for your CMS, and how quickly security patches ship. WordPress's network effects compound over time.
Built-in Features vs Plugin Extensibility
Joomla ships with multilingual support, hierarchical access control, and native caching baked into core. WordPress requires plugins for all three. Joomla's approach means fewer dependencies and a tighter core; WordPress's approach means you install only what you need but accumulate maintenance overhead. For simple sites, WordPress's minimalism wins. For structured, permission-heavy sites, Joomla's defaults save time.
Security Architecture
Joomla's native ACL and permission system gives it stronger default security for sites with complex user roles. WordPress relies on plugins like Wordfence and Sucuri for equivalent protection. However, WordPress's popularity means more eyeballs on vulnerabilities and faster community response. Both require diligent updates—neglected sites on either platform get compromised.
Learning Curve and Developer Availability
WordPress gets a non-technical user productive in about 30 minutes. Joomla takes 2-4 hours minimum and assumes more comfort with CMS concepts like content types and permission layers. The developer availability gap is even wider—WordPress developers outnumber Joomla specialists by roughly 10:1, which directly impacts what you'll pay for custom work and how fast you can get help.
Long-Term Viability and Migration Risk
WordPress's dominance is stable and self-reinforcing. Joomla's decline raises legitimate concerns about long-term viability—fewer extensions get maintained, fewer hosts offer optimized plans, and the community shrinks. Starting a new project on Joomla in 2026 carries real platform risk. If you're already on Joomla and it works, fine—but plan your exit strategy.

| Base JS bundle | ~80-120KB | ~50-150KB (varies heavily by theme/plugins) |
| Native caching | Built-in page and component caching | Requires plugins (WP Super Cache, W3 Total Cache) |
| Lighthouse range | 70-90 | 60-95 |

Joomla
- Native multilingual support without plugins—handles language switching, content association, and URL routing out of the box.
- Built-in hierarchical access control lets you manage complex user permissions without third-party extensions.
- Native caching system delivers solid performance without plugin overhead or configuration complexity.
- Structured content categorization is more flexible than WordPress's default post/page model.
- Stronger default security posture with granular permission settings baked into core.
- Market share declining steadily—down 20% since 2024, now under 2% of all websites.
- Steeper learning curve (2-4 hours vs 30 minutes for WordPress) discourages non-technical users.
- Shrinking developer pool and fewer managed hosting providers make long-term maintenance riskier.
- Extension ecosystem is an order of magnitude smaller than WordPress's plugin library.
WordPress
- Massive ecosystem—59,000+ plugins and 13,000+ themes mean you can build almost anything without custom code.
- Lowest learning curve of any full CMS—most users are productive within 30 minutes.
- Largest developer talent pool in the CMS world, making it easy and affordable to find help.
- WooCommerce alone powers 20%+ of e-commerce sites, giving you a proven path to selling online.
- Managed hosting options (WP Engine, Kinsta) handle security, backups, and performance tuning automatically.
- Plugin dependency for features Joomla includes natively—multilingual, ACL, and caching all require third-party extensions.
- Popularity makes it the biggest target for automated attacks; security requires active plugin management.
- Performance degrades quickly with plugin bloat—poorly maintained sites can become sluggish.
- The block editor (Gutenberg) still frustrates some users who preferred the classic editor workflow.
When to Choose Joomla
- Your site requires native multilingual content management and you want to avoid plugin dependencies for core functionality.
- You're building a membership site, intranet, or directory with complex user role hierarchies.
- You have in-house PHP developers comfortable with Joomla's architecture and don't need a large freelancer market.
- You're maintaining an existing Joomla site that works well and migration costs outweigh the benefits.
When to Choose WordPress
- You're a small business that needs a professional site fast with minimal technical expertise.
- You need e-commerce and want the mature WooCommerce ecosystem with thousands of extensions.
- Long-term maintainability matters—WordPress's market dominance ensures ongoing support, hosting options, and developer availability.
- You plan to use WordPress as a headless CMS with a modern frontend like Next.js or Astro for maximum performance.

Frequently Asked Questions
Is WordPress still better than Joomla in 2026?
For most small businesses? Yeah, WordPress is the right call. It holds 60%+ of the CMS market while Joomla sits at a declining ~2%. That gap alone says plenty. You're looking at 59,000+ plugins versus 9,000 extensions, a much gentler learning curve, lower maintenance costs, and developers you can actually find and hire. Joomla only makes sense if you genuinely need native multilingual support or granular access control without bolting on plugins.
Is Joomla more secure than WordPress?
Out of the box, Joomla's native security is actually stronger—it ships with hierarchical access control lists and granular permissions that WordPress just doesn't have without something like Wordfence. But here's the thing: WordPress's larger attack surface comes from its popularity, not some fundamental architectural flaw. Both platforms run on PHP/MySQL. What really determines your security posture is maintenance habits, hosting quality, and how consistently you apply updates. The CMS you chose is almost beside the point.
How much does it cost to migrate from Joomla to WordPress?
A typical small business Joomla-to-WordPress migration will run you $500–$2,000 and takes one to two weeks. Free plugins like FG Joomla to WordPress handle content export well enough. The real costs—in both time and money—come from rebuilding custom templates, setting up SEO redirects, and putting everything through proper staging before go-live. If your site has custom access control or multilingual setups, expect to pay more. Plugin configuration on that end gets complicated fast.
Which CMS is better for SEO: Joomla or WordPress?
WordPress wins the SEO battle in practice. Yoast SEO and Rank Math hand you full control over meta tags, schema markup, sitemaps, and content analysis. Joomla has built-in SEO tools, sure, but they feel unfinished and the plugin ecosystem for serious SEO work is thin. WordPress also plays nicer with Google's tooling, and when algorithm changes drop, the WordPress community responds quickly. With Joomla, you're often waiting.
Does Joomla have any advantages over WordPress?
There are a few, and they're worth knowing. Joomla ships with native multilingual support—no plugin needed. Its built-in access control is genuinely more sophisticated, which makes it a better fit for membership sites or intranets. Native caching works well without plugin overhead. Content categorization is more structured from day one. These advantages actually matter for mid-complexity sites with specific permission requirements. For your typical small business site, though? They rarely come into play.
Should a small business start a new site on Joomla in 2026?
Almost certainly not. Joomla's market share has dropped 20% since 2024. Fewer developers specialize in it, hosting options are shrinking, and the extension ecosystem isn't growing. Building on Joomla today means betting on a platform that's losing momentum—and that's a rough position to be in a couple years from now. For new projects in 2026, WordPress, Astro, or a headless CMS paired with Next.js are all far better long-term bets.
