Headless CMS with a visual composer

Compose content visually.
Publish it into your site.

RuleCMS is a headless CMS. Marketers build widgets in a drag-and-drop composer. Developers embed them in React — or any stack — through an SDK or API. Preview on every device, publish to staging, then production, with history you can diff and revert.

What makes RuleCMS different

Every claim is shipped today — not roadmap fiction. Explore the docs for implementation detail.

Composer

Visual composer and headless API — together

Marketers get drag-and-drop with per-device preview. Developers get JSON editing, a headless content API, and the @rulecms/widget-react SDK. Nobody blocks the other.

Developer integration
Collections

Create once, embed everywhere

Build reusable widgets and collections. Embed across any number of sites and apps. Update centrally and republish — every reference updates.

Reusable content
Publishing

Publish fearlessly with full version history

Append-only semantic versions. Compare any two versions visually and in JSON. One-click republish to revert live content — audit trail preserved.

How publishing works
Performance

Fast by design

Server-rendered delivery, edge caching with automatic invalidation on republish, and globally distributed media with responsive sizing — fast without extra tuning.

How delivery stays fast
RBAC

162 permissions across 70 roles

View → Manage → Admin progression on every resource. Control who publishes to staging vs. production separately — enforced at data, API, and UI layers.

Pricing

Unlimited seats — no per-person fees

How it works

From first draft to production embed — with staging gates and full audit history at every step.

  1. Compose

    Drag-and-drop in the visual composer — or edit JSON directly.

  2. Preview

    Switch between phone, tablet, and desktop previews live.

  3. Publish to staging

    Ship to staging first. Permissions gate who can promote.

  4. Promote to production

    Separate production permissions. Full history at every step.

  5. Embed anywhere

    Headless API, React SDK, or hosted render — one publish, many surfaces.

Embed in minutes

Deliver published content via the React SDK, headless content API, or hosted render pages. Three environments with scoped API tokens.

RuleCMS vs. typical seat-priced CMS

Most platforms meter seats and gate enterprise features behind premium tiers. RuleCMS includes them by default.
