MODX vs WordPress: どちらのCMSを選ぶべき？
MODX vs WordPress: 柔軟性 vs エコシステム
Choose MODX if you're a developer who wants total HTML control, minimal security risk, and zero frontend bloat — you'll write every line of output yourself. Choose WordPress if you need a massive plugin ecosystem, fast time-to-launch, and a content editing experience that non-technical team members can handle without training. MODX rewards craftsmanship; WordPress rewards speed and ecosystem leverage.

What is MODX?
MODX is an open-source PHP CMS that prioritizes developer freedom over convention. Unlike WordPress, it imposes zero frontend opinions — no theme framework, no required CSS or JS, no prescribed HTML structure. You build templates from scratch using MODX tags, chunks (reusable HTML blocks), snippets (PHP logic), and template variables (custom fields).
What is WordPress?
WordPress is the dominant open-source CMS, powering roughly 43% of all websites. It offers a full-featured admin interface, the Gutenberg block editor, a massive plugin ecosystem, and deep community support. WordPress works for everything from blogs to enterprise sites, though its flexibility often comes at the cost of performance and code cleanliness.
Key Differences
Template & Markup Philosophy
MODX outputs exactly the HTML you write — nothing more, nothing less. There's no theme framework wrapping your content in divs you didn't ask for. WordPress themes follow a template hierarchy with hooks, filters, and the loop, which provides structure but also injects markup, classes, and inline styles you may not want. For developers who care about clean, semantic HTML, MODX is in a different league.
Security Posture
WordPress's market dominance makes it the number one target for automated attacks, and its plugin ecosystem is the primary vulnerability vector. MODX's tiny market share and smaller extension ecosystem mean fewer attack surfaces and less automated targeting. MODX's architecture also doesn't execute PHP in templates by default, reducing the risk of injection attacks through content.
Ecosystem & Community Size
WordPress has 60,000+ plugins, thousands of themes, and a developer community that dwarfs every other CMS combined. MODX has roughly 1,500 extras and a small but dedicated community. This means WordPress solves most problems with an install click, while MODX often requires custom development. The tradeoff is control versus convenience.
Content Editing Experience
WordPress's Gutenberg editor offers a visual block-based editing experience that non-technical users can learn quickly. MODX's manager interface is functional but developer-oriented — content editors work with defined template variables and resource fields rather than visual blocks. For teams with non-technical editors, WordPress provides a smoother editing workflow out of the box.
Headless & API Capabilities
WordPress ships with a built-in REST API and has a mature GraphQL layer via WPGraphQL, making it a strong headless CMS option backed by enormous community tooling. MODX can serve content via API but requires custom endpoint development or community extras. If you're building a headless frontend with Next.js or Astro, WordPress gives you more to work with immediately.
Performance Comparison
| Metric | MODX | WordPress |
|---|---|---|
| TTFB | Fast — outputs only what you template | Varies — plugin-heavy sites can be slow without caching |
| Build tool | N/A (dynamic CMS) | webpack (Gutenberg), varies by theme |
| Base JS bundle | 0KB (no frontend JS required) | ~200-400KB (varies heavily by theme/plugins) |
| Database queries | Minimal — efficient xPDO ORM | Can balloon with plugins — 50-200+ queries common |
| Lighthouse range | 95-100 | 50-95 (highly variable) |
SEO Comparison
| SEO Feature | MODX | WordPress |
|---|---|---|
| SSG support | ✗ | Via static export plugins or headless setups |
| SSR support | ✓ | ✓ |
| Schema markup | ✓ | ✓ |
| Meta tag control | ✓ | ✓ |
| Sitemap generation | ✓ | ✓ |
| Clean URL structure | ✓ | ✓ |
MODX
- Produces exactly the HTML you write — zero markup bloat or framework wrappers.
- Security track record is excellent due to small attack surface and no massive plugin dependency chain.
- Template variables (TVs) and custom manager pages give flexible content modeling without plugins.
- Context system allows multi-domain setups from a single installation.
- RBAC permissions are granular and built into core — no plugin needed.
- Small community means fewer tutorials, Stack Overflow answers, and ready-made solutions.
- No visual page builder or Gutenberg-style block editor out of the box.
- Finding MODX developers or agencies is significantly harder than WordPress.
- Extension ecosystem is limited — niche features often require custom development.
WordPress
- Largest ecosystem in CMS history — there's a plugin for virtually everything.
- Gutenberg block editor provides a solid visual editing experience for non-technical users.
- Massive talent pool — finding WordPress developers and designers is trivial.
- WP REST API and WPGraphQL make headless WordPress a viable and well-documented pattern.
- Community support through forums, tutorials, and courses is unmatched.
- Plugin dependency creates security vulnerabilities, update fatigue, and compatibility conflicts.
- Frontend output is often bloated — themes inject unnecessary markup, styles, and scripts.
- Performance degrades quickly as plugins accumulate, requiring caching layers and optimization plugins.
- Customization beyond theme options often means fighting the WordPress way rather than building freely.
When to Choose MODX
- You need pixel-perfect markup control with absolutely no CMS-injected bloat.
- Security is a top priority and you want to minimize your attack surface.
- Your development team is comfortable building custom solutions rather than assembling plugins.
- You're building a content-heavy site where editorial flexibility matters more than out-of-box features.
When to Choose WordPress
- You need to launch quickly and want access to thousands of pre-built themes and plugins.
- Non-technical editors need a familiar, well-documented admin interface with visual editing.
- You're building ecommerce with WooCommerce or need advanced membership/LMS functionality.
- Hiring flexibility matters — WordPress developers are the most available CMS talent pool.

Frequently Asked Questions
Is MODX more secure than WordPress?
MODX has a much smaller attack surface than WordPress. That massive plugin ecosystem WordPress depends on? It's also WordPress's biggest security liability. MODX doesn't have that problem. Its template system won't execute PHP by default, and because it holds a smaller market share, automated attacks rarely bother targeting it. That said, neither platform lets you skip proper server hardening and regular updates.
Can MODX be used as a headless CMS?
MODX can serve content via REST API, and the community's built packages for headless workflows. But it wasn't designed headless-first the way Strapi or Sanity were. You'll need custom development to build out API endpoints. WordPress has a more mature REST API out of the box — going headless there just takes less work, no extra setup required.
Is MODX harder to learn than WordPress?
MODX has a steeper learning curve, especially for non-developers. There's no visual theme customizer, no drag-and-drop builder included. You're working directly with templates, chunks, and snippets. For developers comfortable with PHP and HTML, that's actually a feature — MODX doesn't impose opinionated structures on you. WordPress is easier to get started with, sure, but getting clean, maintainable code out of it? That takes real effort.
Why do developers prefer MODX over WordPress?
Developers who choose MODX tend to care about clean markup, zero-bloat output, and a system that stays out of their way. MODX templates produce exactly the HTML you write — nothing more, nothing less. No theme framework injecting wrapper divs. No enqueued scripts you never asked for. Just a blank canvas with powerful templating primitives.
Does MODX have enough plugins and extensions?
MODX has around 1,500 extras compared to WordPress's 60,000+ plugins. For common needs — forms, SEO, caching, galleries — solid MODX packages exist. For niche requirements like LMS, membership systems, or advanced ecommerce, WordPress has far more options. Where WordPress has a plugin ready to install, MODX often means writing custom code. That's just the tradeoff.
Should I migrate from WordPress to MODX?
Migrate to MODX if you're tired of plugin conflicts, constant security patches, bloated output, or wrestling with theme frameworks just to get clean HTML. MODX hands developers total control. Don't migrate if your workflow depends on the WordPress ecosystem — WooCommerce, Yoast, Elementor — or if non-technical editors need a polished, beginner-friendly admin interface. Know your priorities before you commit.
