Companies Using Joomla

As CMO at TechnologyChecker.io, I've analyzed the Joomla ecosystem across 111,637 active domains matched to 68,405 company profiles (59.07% match rate). Joomla tells a unique story in the CMS market: a two-decade-old platform whose active domain count peaked in December 2024 and is now declining, yet whose institutional core (governments, universities, defense organizations) shows no sign of leaving. Here's what our data reveals.

1. Growth Trajectory: Two Decades of Rise, Then Retreat

Joomla's detection history stretches back to September 2005, when we first tracked 4 active domains. By December 2024 it reached 111,737, but that peak masks a deeper story. Total domains (including historical detections) peaked at 261,000 in late 2017 and have declined to 87,399 by July 2025. The gap between total and active domains has been narrowing, which means Joomla is no longer attracting enough new sites to offset departures. The 543,163 previously-used count means roughly 5 out of every 6 domains that ever ran Joomla have moved on.

Sales Signal: The declining trajectory creates a growing pool of recently migrated organizations, specifically sites that left Joomla in the last 1-3 years. In the last year alone. 2,682 companies moved to WordPress and 294 to Wix. These are organizations in active transition, likely still evaluating their new stack and open to complementary tools.

2. Customer Profile: Institutional, European, Micro-Business

Three characteristics define the typical Joomla customer. First, 85% have 10 or fewer employees, the largest micro-business concentration of any major CMS in our data. Second. They're disproportionately European: Germany leads at 17%, ahead of the US at 13%. The DACH+Benelux region alone accounts for 25%+ of all Joomla companies. Third, the notable companies skew heavily toward the public sector: NATO, the Government of Canada, the United States Courts, Turkey's Ministry of Health, and multiple 10,001+ employee universities.

This duality (85% micro-businesses plus a visible institutional tail) means Joomla serves two distinct audiences with different motivations. The micro-businesses chose it because it was free. The institutions chose it because it's open-source, self-hosted, and compliant with public-sector procurement rules.

Sales Signal: Segment your outreach by company size. For the 85% micro-businesses (1-10 employees), lead with simplicity and migration assistance, as these organizations lack dedicated web teams and are the most receptive to managed alternatives. For the institutional tail (government, education, 200+ employees), lead with data sovereignty, GDPR compliance, and open-source licensing, the reasons they chose Joomla in the first place.

3. Industry & Geographic Concentration

Construction leads at 4.95%, followed by Retail (3.80%), Business Consulting (3.79%), IT Services (3.41%), and Medical Practices (2.56%). No single industry exceeds 5%, which makes Joomla genuinely horizontal, a rarity among CMS platforms. The IT Services concentration (3.41%) is worth noting: many of these are web agencies that built client sites on Joomla and may influence multiple downstream migrations.

Germany's #1 position (11,612 companies, 17%) reflects three factors: the strong German-language Joomla community (Joomla.de), EU open-source mandates, and GDPR-driven preference for self-hosted systems. Italy (8.0%), France (4.9%), Spain (3.7%), and the Netherlands (4.6%) form the rest of the European concentration.

Sales Signal: European-focused SaaS companies should treat Joomla detection as a proxy for "prefers open-source, privacy-conscious, self-hosted solutions." Target Construction (4.95%) and Medical Practices (2.56%) in Germany specifically. These segments combine data sensitivity with real budgets and established Joomla commitments.

4. Migration Patterns: The WordPress Exodus

The numbers are blunt: Joomla lost 42,106 companies to WordPress while gaining only 8,459, a 5:1 loss ratio. This is the dominant migration pattern in our entire dataset. WordPress gains from Joomla outpace any other CMS-to-CMS flow we track. Smaller but growing losses to Wix (net -2,610) and Squarespace (net -1,467) compound the trend.

Interestingly, the Drupal exchange is nearly balanced: 1,028 moved from Drupal to Joomla, 980 went the other way. These two open-source CMS platforms trade users at equilibrium, while both lose to hosted solutions.

Sales Signal: For migration service providers, the 111,637 remaining Joomla domains are the largest addressable migration opportunity in the open-source CMS space. Focus on the 85% micro-businesses who lack development resources. G2 and Capterra reviewers flag "confusing interface" and "painful version upgrades" as top complaints. Lead with "zero-downtime migration" and "automatic updates" messaging.

5. Tech Stack Ecosystem

Joomla's tech stack has a unique fingerprint. 38.29% of Joomla sites still load MooTools, the JavaScript framework bundled with Joomla's core. This makes MooTools detection a reliable secondary signal for identifying Joomla sites. Google Analytics leads at 43.45%, while Facebook Pixel (5.49%) and Hotjar (1.24%) show modest marketing tool adoption, far lower than the 60%+ Facebook Pixel rates we see on Shopify or Privy domains.

E-commerce overlap is minimal: WooCommerce at 1.49%, Ecwid at 0.48%, PrestaShop at 0.35%. Joomla is a content CMS, not a commerce platform. The low marketing and e-commerce tool overlap suggests Joomla's user base is less commercially oriented than other CMS audiences, consistent with the government, education, and nonprofit profile.

Sales Signal: The MooTools detection signal (38.29% overlap) gives you a secondary targeting dimension. Companies running MooTools are almost certainly Joomla users, providing a proxy filter unavailable to competitors who only track CMS detection.

G2 Review Signals

From a marketing perspective, G2 reviews confirm what our migration data already shows. Users praise extensive customizability (4 mentions) as Joomla's top strength, which explains why institutions like NATO and the Government of Canada stick with it. But the top complaint, confusing interface (3 mentions), directly correlates with the 42,106 companies that migrated to WordPress. For sales teams targeting Joomla users, lead with interface simplicity as the wedge.

Key Takeaways

• Peak and decline. Active domains peaked at 111,737 in December 2024. Total domains peaked at 261,000 in 2017. Five out of six domains that ever used Joomla have moved on.
• WordPress exodus. 42,106 companies lost to WordPress at a 5:1 ratio, the largest CMS-to-CMS migration in our data.
• European institutional core. Germany #1 at 17%, heavy government and university presence. These users chose Joomla for compliance, not convenience.
• Ultra-SMB plus institutions. 85% micro-business, but notable 10,001+ employers like NATO, Fujitsu, and Government of Canada.
• Capterra confirms the story. 91% positive on flexibility, 71% negative on version upgrades; the operational burden drives migration.

Sales Applications

Outreach template: "We noticed your organization uses Joomla. 71% of Capterra reviewers cite version upgrades as their biggest frustration. Here's how [your solution] eliminates that maintenance burden while preserving the multilingual support and access control your team relies on."

Targeting strategy: Filter for Joomla + Germany + Construction or Medical Practices. This segment combines the highest geographic concentration (17%) with the industries most likely to have data sensitivity requirements and real IT budgets. For migration services, focus on the 85% micro-businesses (1-10 employees), as they lack the development resources to maintain Joomla long-term.

Competitive angle: Use the MooTools co-detection signal (38.29%) as a secondary Joomla identifier. Target sites still on Joomla 4.x or earlier, as they face the exact version migration pain (71% Capterra negative) that makes them receptive to managed alternatives or migration services.
