Joomla turns 21 today, 17 August 2026. Twenty-one years after the Mambo fork on 17 August 2005, it is still a production-ready open-source CMS for multilingual, ACL-heavy, and enterprise-style websites. Market share is smaller than WordPress. The next chapter depends on developer confidence, smoother upgrades, and core strengths that still outpace many competitors.
I have used Joomla since the Mambo days. At Infyways we still ship Joomla extensions used worldwide. Looking only at market share, it is easy to say Joomla lost. Looking at architecture, security, and real project fit, that conclusion is incomplete. Today is a birthday, not a eulogy.
What you will learn
- Why 17 August 2026 is Joomla’s 21st birthday, and how the 2005 fork actually started
- Why Joomla’s decline was mostly confidence and migration friction, not weak technology
- Which core capabilities still make Joomla a strong CMS choice in 2026
- Where Joomla 5.4.x and 6.x stand on the current roadmap
- When to choose Joomla instead of trying to copy WordPress
17 August 2026: Joomla is 21
The date is not marketing copy. The Joomla project and the official 20 Years of Joomla timeline put the start of the story on 17 August 2005: a fork of Mambo so the CMS would stay truly open source. The name Joomla (from the Swahili jumla, “all together”) was announced on 1 September 2005. Joomla 1.0 shipped on 22 September 2005.
That makes today, 17 August 2026, twenty-one years of a volunteer-run CMS with no corporate owner. Last year’s 20th birthday week is documented in the Joomla Community Magazine. Year 21 is quieter, which is fine. The work is in releases, not merch shops.
| Date | Milestone |
|---|---|
| 17 August 2005 | Mambo fork. The project that became Joomla begins. |
| 1 September 2005 | The name Joomla is announced. |
| 22 September 2005 | Joomla 1.0 ships. |
| 17 August 2025 | Official 20th anniversary. |
| 14 October 2025 | Joomla 6.0 and Joomla 5.4 ship together. |
| 17 August 2026 | Joomla turns 21. |
| 18 August 2026 | Planned Joomla 5.4.8 and 6.1.3 on the project roadmap. |
| 21 to 22 August 2026 | Global Pizza, Bugs and Fun contributor event. |
Joomla market share vs WordPress in 2026
According to W3Techs, Joomla currently powers about 1.2% of all websites and roughly 1.7% of sites that use a known CMS. WordPress powers over 43% of all websites and nearly 62% of the CMS market.
| Signal | Joomla | WordPress |
|---|---|---|
| Share of all websites | ~1.2% | ~43%+ |
| Share of known CMS market | ~1.7% | ~62% |
| Core multilingual | Native | Usually plugin-based |
| Granular ACL | Built into core | Often plugin-dependent |
| Best-fit use cases | Complex, multilingual, permission-heavy sites | Publishing speed and mass adoption |
Bottom line: market share measures popularity. It does not measure whether Joomla is still the better tool for a university portal, government site, membership platform, or multi-language enterprise build.
Joomla never lost because of technology
The most common misconception is that Joomla declined because it could not keep up technically. I disagree. Modern Joomla is one of the strongest releases the project has ever shipped.
- Native multilingual support
- Enterprise-grade Access Control Lists (ACL)
- Custom Fields for structured content entities
- Template overrides for full front-end control
- Web Services / API endpoints for headless and hybrid builds
- Modern PHP architecture, cleaner code, and a strong security posture
Many of these capabilities existed in Joomla before they became table stakes elsewhere. Technology was never the core weakness.
The real challenge was confidence
The harder problem was investment confidence. Major releases modernized the platform, but they also created painful migrations, broken extensions, template rewrites, and changing APIs.
Businesses delayed upgrades. Developers spent months on compatibility instead of new products. Agencies hesitated before recommending Joomla for long-term roadmaps. Some extension authors moved ecosystems or stopped shipping altogether.
That uncertainty, not a lack of features, slowed Joomla’s commercial momentum.
The biggest loss was developers, not just users
A CMS is only as strong as the ecosystem around it: extension developers, template creators, agencies, hosts, educators, and community contributors. When developers stop building, users eventually stop arriving. That developer attrition was Joomla’s deepest challenge over the last decade.
What Joomla still gets right in 2026
Joomla still wins on flexibility, security, scalability, and developer freedom. Unlike platforms that outsource essential capability to plugins, Joomla keeps many advanced features in core.
- Multilingual: still among the best native CMS implementations
- Permissions: ACL depth most competitors still struggle to match cleanly
- Architecture: enough freedom to build complex applications, not only brochure sites
- Trust: a long security track record with businesses, education, and public-sector projects
- Governance: still community-run. No venture owner can flip the license.
As cybersecurity and data ownership become non-negotiable, those strengths matter more, not less. For a practical hardening view, see our Joomla security 2026 guide.
Where Joomla 5.4 and Joomla 6 stand on its 21st birthday
On 14 October 2025, the project released Joomla 6.0 and Joomla 5.4. 5.4 is the bridge. 6.x is the new major line, with automatic core updates and a Backward Compatibility 6 plugin to reduce upgrade risk.
The Joomla roadmap (updated 16 August 2026) is the right snapshot for today:
- Joomla 5.x current: 5.4.7. Bugfix only. Regular bugfix support until 13 October 2026. Security-only until 12 October 2027.
- Joomla 6.x current: 6.1.2. Bugfix support until 17 October 2028. Security-only until 16 October 2029.
- Tomorrow, 18 August 2026: planned 5.4.8 and 6.1.3.
- Joomla 6.2.0 is aimed at 13 October 2026, with Beta 1 listed for 18 August 2026.
This week the community also runs Pizza, Bugs and Fun on 21 to 22 August 2026, a hybrid global event for testing, docs, and patches, including work toward Joomla 6.2. Birthdays are nice. Contributor weekends keep the CMS alive.
Why I still build with Joomla
People ask why I keep investing after two decades. Because the product still solves hard problems well. At Infyways we keep releasing and maintaining Joomla products, and we stay active on the Joomla Extensions Directory. If we did not believe Joomla had a future, we would not keep putting time and capital into that ecosystem.

Joomla does not need to become WordPress
Comparing Joomla only to WordPress misses the point. WordPress won by making publishing extremely simple. Joomla won by giving developers and organizations deep flexibility. That identity should stay.
Instead of chasing raw market share, Joomla should keep improving what already makes it exceptional, while making onboarding, upgrades, and sustainable extension businesses easier.
Key takeaways
- Joomla is 21 today, 17 August 2026, counting from the 17 August 2005 Mambo fork.
- Smaller market share does not mean the CMS is obsolete for complex builds.
- Core multilingual, ACL, Custom Fields, and Web Services remain durable advantages.
- Joomla 6.1.2 is the current major line. 5.4.x is still supported. 5.4.8 and 6.1.3 are on the calendar for 18 August 2026.
- Joomla should double down on its identity, not imitate WordPress.
Frequently asked questions
When did Joomla turn 21?
On 17 August 2026. The project began as a Mambo fork on 17 August 2005, was named Joomla on 1 September 2005, and shipped 1.0 on 22 September 2005.
Is Joomla still worth using in 2026?
Yes, when you need native multilingual, deep ACL, structured content, or a flexible architecture for complex sites. It is not always the fastest path for a simple brochure blog, but it remains a strong CMS for demanding projects.
Did Joomla lose to WordPress because of bad technology?
No. Joomla’s harder problem was confidence: migration pain, extension compatibility risk, and uncertain long-term investment signals. The core technology stayed competitive.
What should I run on Joomla’s 21st birthday?
Joomla 6.1.2 on the 6.x line, or 5.4.7 if you are still on 5.x. Watch for 6.1.3 and 5.4.8 around 18 August 2026 on the official roadmap, then plan toward 6.2 later in 2026.
Who should choose Joomla over WordPress?
Teams building multilingual portals, permission-heavy applications, government or education sites, or custom systems that benefit from core ACL and overrides, rather than assembling the same stack from many plugins.
Conclusion
Twenty-one years in, Joomla’s next chapter will not be written by market-share charts alone. It will be written by developers who keep building, businesses that keep investing, and a community that treats security, ownership, and flexibility as first-class product values. I am still building extensions, still contributing on the JED, and still recommending Joomla when it is the right fit, not from nostalgia, but because the platform still has enormous potential.
Happy 21st birthday, Joomla. Here’s to the next 21 years.
