Explore the Latest Insights and Performance Analysis of Popular Open Source CMS
In the fast-evolving digital landscape of 2025, open source content management systems (CMS) remain the backbone for millions of websites, blogs, and enterprise platforms. From powering personal portfolios to driving complex e-commerce sites, CMS like WordPress, Joomla, Drupal, Ghost, Strapi, TYPO3, and Craft CMS offer flexibility, cost-effectiveness, and robust ecosystems. This report dives into the latest data on trends, security, user adoption, customization, community support, and performance benchmarks. Drawing from recent industry analyses, we'll provide data-driven comparisons to help developers, marketers, and business owners select the ideal CMS for their needs.
Whether you're scaling a startup or optimizing a legacy site, staying ahead means understanding how these platforms stack up in a year dominated by AI integration and headless architectures.
User Adoption and Market Share
Open source CMS continue to dominate the web, with over 80 million sites relying on them globally. As of November 2025, WordPress holds an unchallenged lead, powering 43.1% of all websites (and 60.5% of the CMS market). However, the landscape is diversifying, with headless and API-first options like Strapi gaining traction among developers.
Here's a snapshot of market shares for key open source CMS (based on W3Techs data, November 2025):
| CMS | % of All Websites | % of CMS Market | Key Adoption Notes |
|---|---|---|---|
| WordPress | 43.1% | 60.5% | Dominant for blogs, small businesses; 455M+ sites. |
| Joomla | 1.4% | 1.9% | Popular for mid-sized sites; steady but niche. |
| Drupal | 0.8% | 1.1% | Enterprise favorite; used by 1% of top 10K sites. |
| TYPO3 | 0.4% | 0.5% | Strong in Europe for multilingual sites. |
| Ghost | 0.1% | 0.1% | Rising for newsletters and publishing. |
| Strapi | <0.1% | <0.1% | Headless leader; 68K+ GitHub stars, developer-focused. |
| Craft CMS | <0.1% | <0.1% | Custom builds; growing in agencies. |
Sources indicate WordPress's share has stabilized around 62-65% of CMS usage, while others like Joomla and Drupal hover at 2% combined in broader surveys. Emerging players like Strapi are projected to capture more developer mindshare in headless setups.
Key Trends Shaping Open Source CMS in 2025
2025 has seen a surge in headless CMS architectures, decoupling content from presentation for omnichannel delivery across web, mobile, and IoT. Platforms like Strapi and Ghost excel here, enabling Jamstack deployments with static site generators.
AI integration is another powerhouse trend, with CMS embedding tools for content generation, personalization, and SEO optimization. WordPress's Gutenberg blocks now support AI plugins for auto-drafting, while Drupal's Layout Builder incorporates machine learning for dynamic layouts. Expect 70% of new CMS projects to include AI by year-end, per industry forecasts.
Other shifts include composable CMS (mixing microservices) and sustainability-focused performance (e.g., lighter core footprints to reduce carbon emissions). Security regulations like the EU's Cyber Resilience Act are pushing all platforms toward proactive vulnerability disclosure.
Security Updates: Staying Ahead of Threats
Security remains paramount, with open source CMS facing a 34% rise in vulnerabilities ecosystem-wide. Here's the latest:
- WordPress: The 2025 State of Security report highlights 7,966 new vulnerabilities (mostly in plugins), with XSS attacks comprising 50%. Key update: Version 6.8.1 (June 2025) introduced enhanced defenses against RCE exploits. Over 500K sites infected in 2024, emphasizing virtual patching tools like Patchstack.
- Joomla: Joomla 5.3.4 (September 2025) patched critical SQL injections and MFA bypasses. Joomla 5.4 (October 2025) added automatic core updates, a game-changer for compliance.
- Drupal: Upcoming core release on November 12, 2025, addresses advisories like SA-CORE-2025-001 (high-severity access bypass, October 2025) and SA-CONTRIB-2025-002 (malicious file uploads, September 2025). Drupal 7 reached EOL in January 2025, urging migrations.
- Ghost: Version 6.0 (August 2025) bolstered 2FA with device verification and email hardening against phishing.
- Others: Strapi's v5 (mid-2025) fixed 20+ auth flaws; TYPO3 and Craft emphasize modular security via extensions.
Pro tip: Enable auto-updates and use WAFs tailored to CMS-specific threats—33% of vulns go unpatched otherwise.
Performance Analysis and Benchmarks
Performance varies by architecture: Traditional monolithic CMS like WordPress excel in simplicity but can lag under load without optimization, while headless options shine in scalability.
Recent 2025 benchmarks (e.g., from comparative tests) show:
- WordPress: Average TTFB (Time to First Byte) of 200-400ms on shared hosting; scales to 10K+ concurrent users with caching (e.g., WP Rocket). Lags Drupal in raw queries but wins on plugin-optimized sites.
- Drupal: Tops enterprise benchmarks with 100-200ms TTFB and handles 50K+ users via caching layers; 20% faster than Joomla for complex sites.
- Joomla: Solid mid-tier (300ms TTFB), but extension bloat can hit 500ms; better than WP for multilingual without plugins.
Headless CMS like Strapi and Ghost average 50-150ms, ideal for CDNs and edge computing—up to 5x faster for global delivery. In high-traffic simulations, Drupal edges out for compliance-heavy sectors, while Ghost leads for publishing (sub-100ms).
Customization Capabilities
Open source CMS thrive on extensibility, but depth varies:
- WordPress: Unmatched plugin ecosystem (60K+); easy theming via blocks. Ideal for quick customizations, though core mods require child themes.
- Drupal: Module-based for enterprise workflows; excels in API-driven custom entities. Steeper curve but infinite flexibility.
- Joomla: Template overrides and extensions for mid-level tweaks; strong for multilingual without bloat.
- Ghost/Strapi: Headless-first, perfect for custom frontends (React/Vue); Strapi's JS extensibility suits devs.
- TYPO3/Craft: TYPO3 for vast site trees; Craft for bespoke e-commerce without limits.
In comparisons, Drupal scores highest for complex customizations (9/10), while WordPress leads ease (8/10).
Community Support and Ecosystem
Vibrant communities drive longevity. WordPress's 1M+ active users dwarf others, with forums and events like WordCamp fueling innovation. GitHub metrics (approximate, mid-2025):
| CMS | Stars (GitHub) | Forks | Contributors | Activity Notes |
|---|---|---|---|---|
| WordPress | ~20K (mirror) | 10K+ | 1K+ | Massive; daily commits via Trac. |
| Joomla | 4.5K | 3K | 500+ | Active JED directory. |
| Drupal | 6K | 4K | 800+ | DrupalCon buzz. |
| Ghost | 45K | 3.8K | 300+ | Newsletter focus. |
| Strapi | 68K | 8.7K | 1K+ | Rapid headless growth. |
| Craft CMS | 2.5K | 500 | 200+ | Agency-driven. |
| TYPO3 | 1.2K | 800 | 648 | Enterprise stable. |
WP's scale means faster issue resolution; Strapi's dev-first vibe accelerates headless adoption.
