Simple or Flexible?
Pick Both.

Every headless CMS makes you choose: easy but limiting, or powerful but complex. InfernoCMS gives you both.

content.config.ts
pages:
blocks:
hero:
title: text
description: richtext
ctaButton1: link
ctaButton2: link
features:
items[]:
icon: image
title: text

Define any structure. Any depth.

Ghost's simplicity. Payload's flexibility.

When someone asks "what CMS should I use?", the answer should be obvious.

Zero to Content in 60 Seconds
No mandatory config files, no required environment variables, no database setup for local dev. Just run the CLI and start creating content.
Code is the Source of Truth
Content schemas live in your codebase, version-controlled, reviewable, deployable. Change code → system adapts. No clicking through admin panels.
PGlite to Postgres
Embedded PostgreSQL (PGlite) for development, same code works with full Postgres in production. No migration headaches.
Simple REST API
GET, POST, PUT, DELETE. That's it. No query languages, no special syntax. Any developer (or AI agent) can use it without reading docs.
AI-Native by Design
Simple, predictable endpoints that LLMs and AI agents can call trivially. Built for the age of AI-assisted development.
Sensible Defaults, Escape Hatches
Works perfectly with zero config. Need customization? Opt-in to full Postgres, S3/R2 storage, JWT auth, webhooks, and more.

Define once, use everywhere

Your config file becomes your API, your admin UI, and your TypeScript types. All auto-generated.

content.config.ts
// content.config.ts - This is the entire setup
import { defineConfig, field } from 'infernocms';

export default defineConfig({
  collections: {
    posts: {
      fields: {
        title: field.text({ required: true }),
        slug: field.slug({ from: 'title' }),
        body: field.richtext(),
        cover: field.image(),
        author: field.relation({ to: 'authors' }),
        status: field.select({
          options: ['draft', 'published'],
          default: 'draft'
        }),
      }
    },
    authors: {
      fields: {
        name: field.text({ required: true }),
        avatar: field.image(),
      }
    }
  }
});
