Most headless CMSs give you fields and endpoints. ApexCMS gives you a relational data model — where content types, taxonomies, and entities are connected by design. Query an attorney and get their practice areas, publications, and credentials in one call.
{
"id": "atty_sarah_chen",
"type": "attorney",
"fields": {
"name": "Sarah Chen",
"title": "Partner",
"email": "s.chen@firm.com"
},
"relationships": {
"practice_areas": [
{ "id": "pa_employment", "title": "Employment Law" },
{ "id": "pa_litigation", "title": "Commercial Litigation" }
],
"publications": [
{ "id": "pub_019", "title": "Navigating Workplace Disputes in 2025" }
],
"credentials": [
{ "id": "cred_bar_ny", "title": "New York State Bar" }
]
}
}Deliver content to any frontend — React, Svelte, Next.js, mobile apps, or static site generators. The API returns structured JSON with full relationship data, so you can build exactly the experience you want without fighting the CMS.
Filter by any field, include nested relationships, paginate with cursors, and get predictable responses every time.
Every piece of content in ApexCMS is one of five types. Each type has its own schema, its own API behaviour, and its own editing experience — but they all share the same relationship system.

Editorial content isn't a single rich-text blob. It's composed from discrete blocks — headings, body text, pull quotes, images, video embeds, code snippets, and dynamic content lists. Each block is independently addressable via the API, so your frontend can render them however it needs to.
Content editors get a clean drag-and-drop interface. Developers get structured, predictable JSON.
CDN-delivered assets with automatic format optimization (WebP, AVIF). Edge caching for API responses. Handle millions of content items without degradation.
Your content is served from the edge, close to your users. API responses are cached intelligently and invalidated on publish. Media assets are automatically resized, optimized, and delivered in the best format for each device.
A CMS that gets out of your way. Clean APIs, predictable data structures, and a content model that matches how you think about your domain — not how the CMS thinks about storage.
Clean, predictable endpoints for every content type. Filter, sort, paginate, and include related entities in a single request.
Real-time notifications when content changes. Trigger builds, sync external systems, or run custom workflows automatically.
Define your content architecture with custom fields, relationships, and validation rules. No rigid templates — build exactly what you need.
Compose rich content with reusable blocks — rich text, media, embeds, dynamic lists. Each block is independently queryable via the API.
Granular permissions for every role. Control who can create, edit, publish, and delete at the entity-type level.
Centralised asset management for images, videos, and documents. CDN-delivered with automatic format optimization and responsive variants.
