Decoupled.io vs WordPress (Headless)
Quick Overview
Decoupled.io is a managed headless CMS built on Drupal, purpose-built for decoupled architectures. It ships with GraphQL, JSON:API, a visual page builder (Puck), and 25+ MCP tools for AI agents — all on day one.
WordPress (Headless) is the world's most popular CMS, now commonly used in headless mode via WPGraphQL or the REST API. It's battle-tested, has a massive plugin ecosystem, and is the most familiar CMS for content editors. But headless WordPress is a retrofit — the core architecture was designed for monolithic themes.
Feature Comparison
| Feature | Decoupled.io | WordPress Headless |
|---|---|---|
| Content modeling | Drupal entity system with unlimited custom fields natively | Custom Post Types + ACF/Pods plugins for custom fields |
| API | GraphQL + JSON:API + 25 MCP tools, all native | REST in core, GraphQL via WPGraphQL plugin |
| Visual page builder | Puck editor with drag-and-drop and AI content generation | Gutenberg is block-based but tied to the frontend theme |
| Localization | Full Drupal multilingual in core | Via plugins (WPML, Polylang) |
| Authentication | Drupal auth with SSO, OAuth2, fine-grained permissions | Mature user system, SSO via plugins |
| Taxonomy | Unlimited custom vocabularies, hierarchical terms | Categories and tags, custom taxonomies via code |
| Workflow | Built-in content moderation, revisions, scheduling | Plugins required for advanced workflows |
| Hosting | Managed | Self-hosted (you manage updates and security) |
| Pricing | Flat monthly tier | Free core, pay for hosting + premium plugins |
| AI / MCP tools | 25 native MCP tools for AI agents | Community plugins emerging |
When to choose headless WordPress
- Your content team already uses WordPress and you don't want to retrain
- You have a large library of existing WordPress plugins you rely on
- You want full control over hosting and can handle updates/security yourself
- Your content model is relatively simple (posts, pages, custom post types)
When to choose Decoupled.io
- You need real headless architecture without plugin workarounds
- You want GraphQL and JSON:API as first-class citizens, not bolt-ons
- You need complex content models, advanced workflows, or true multilingual
- You want AI agent / MCP integration out of the box
- You prefer managed hosting with zero DevOps
The architecture difference
WordPress was built for monolithic themes. You can bolt on headless APIs, but you're fighting the grain. Drupal was built for structured content from the start — it has proper entity types, fieldable everything, and an API-first mindset.
If you're building a content-heavy site with complex data relationships, localization, or editorial workflows, Drupal's architecture gives you room to grow. Decoupled.io wraps that architecture in managed hosting so you get the power without the ops burden.
