AI SDK Agents
The headless CMS that's
blazing fast by design.
A self-hosted headless CMS built in Rust. Deliver content at 12,600+ req/s with ~8ms read latency — 10–40x faster than Strapi, Directus, or Ghost.
Unmatched Performance
CMSX optimizes content delivery handling far more concurrency with a fraction of the RAM. Improve your site's SEO and retention by guaranteeing near-instant responses.
* Standardized load tests (100 concurrent connections) under identical network and hardware conditions.
Core Features
From schema definition to content delivery — everything built in from day one.
Dynamic Content Schemas
Define and modify content types from the dashboard — Text, RichText, Number, Boolean, Date, Image, and Reference fields. No code changes or migrations required.
Content Versioning
Every edit creates a new version. Compare changes with visual diffs, roll back to any previous version, and maintain a complete audit trail.
Scheduled Publishing
Set content to publish at a future date with timezone support. Manage a content pipeline with draft, review, scheduled, and published statuses.
Media Library
Upload images and files with drag-and-drop. Organize with folders, automatic WebP conversion, resizing, and inline references from the content editor.
Role-Based Access Control
Three built-in roles — Admin, Editor, and Viewer — with granular permissions per schema. Control who can create, edit, publish, or only read content.
AI Content Generation
Generate drafts, summaries, translations, and field suggestions powered by Claude (Anthropic) — directly from the content editor.
REST API with 30+ Endpoints
Consume content from any frontend — Next.js, Nuxt, SvelteKit, Astro, React Native, or plain HTTP. Structured JSON responses with full pagination.
Webhooks & API Keys
HMAC-SHA256 signed webhooks for content lifecycle events. Scoped API keys with per-key permissions and automatic rotation support.
Enterprise Security
AES-256-GCM field encryption, Argon2id password hashing, JWT + refresh tokens, rate limiting, CORS, CSP/HSTS headers, and HTML sanitization.
Simple API, powerful results
Fetch your content with a single REST call. Structured JSON responses, dynamic field types, and pagination built in.
// Fetch content entries from a schema
const response = await fetch("https://your-instance.com/content/blog-posts", {
headers: {
"Authorization": "Bearer your_access_token",
"Content-Type": "application/json"
}
});
const { data, total, page } = await response.json();
// 12,600+ req/s — ~8ms avg latencyBuilt for developers, by developers
30+ REST endpoints, clear schema documentation, and a straightforward content API. Integrate CMSX into any frontend in minutes, not days.
