Everything you need to ship content

A platform built for developers and content teams to move fast without compromise.

Custom REST API

Define your own endpoints, response shapes, and query parameters. No more fighting rigid API layouts.

Design Your Content Models

Build repeatable content types, fields, and validation rules through an intuitive editor or via API.

Built-in Localization

Handle locale-specific translations and localized responses natively with zero extra setup.

Webhook Triggers

Automate workflows with custom webhooks. Revalidate caches, notify services, or deploy on content changes.

Media & Asset Management

Upload, transform, and deliver images and files with automatic optimization and CDN delivery.

Role-Based Access Control

Granular permissions for owners, admins, editors, and viewers. Control who reads, writes, and publishes what.

API

Your API. Your rules.

Every content model automatically generates RESTful endpoints — but you're not stuck with defaults. Create custom collections, filter by any field, select exact response keys, and embed related content in a single request.

Custom route patterns: /api/posts, /api/products
Field selection & sparse fieldsets
Composite endpoints — embed relations
Language & locale-aware queries
API keys + Webhooks

GET /api/posts

{
    "data": [
        {
            "id": "post_01j...",
            "title": "Hello World",
            "slug": "hello-world",
            "status": "published",
            "author": {
                "id": "usr_...",
                "name": "Jane Doe"
            }
        }
    ],
    "meta": {
        "total": 42,
        "page": 1,
        "perPage": 20
    }
}
