Contentrain

Govern the content your AI ships into code.

Contentrain is a content governance ecosystem for teams and AI agents. Content lives in Git as structured JSON and Markdown. Start locally with the open-source MCP, CLI, and SDK packages. Add Studio when teams need review, roles, media, and delivery. Moving off WordPress? Bridge exports your content for free, and Migrate moves the whole site to Astro.

Most teams don't wake up needing a new content platform. They wake up with hardcoded copy spread across components, no translation path, and AI agents editing strings directly in source files.

Contentrain puts a governed content layer between the agent and your repository:

Agent decides  →  Contentrain enforces  →  Human reviews  →  Any platform consumes
(what content)    (schema, validation,      (branch, diff,     (JSON + Markdown,
                   canonical Git writes)     approval)          SDK, CDN, API)

The content contract never changes — only the surface you operate it from does.

npx contentrain init     # create the .contentrain/ workspace
npx contentrain serve    # open the local review UI

No account, no cloud, no proprietary content format. You now have models, validation, review branches, and a local UI.

Typical path: contentrain init → normalize hardcoded content → review branches → invite teammates into Studio → deliver through CDN/API when needed.

MCP works with Claude Code, Claude Desktop, Cursor, Windsurf, Codex, and any MCP-compatible client.

Before — copy is trapped in components. No structure, no locales, no review.

<h1>Welcome to our platform</h1>
<p>Start your free trial today</p>

After — source uses keys, content lives in Git as structured, translatable data.

<h1>{t('hero.title')}</h1>
<p>{t('hero.subtitle')}</p>

// .contentrain/content/marketing/hero/en.json
{ "title": "Welcome to our platform", "subtitle": "Start your free trial today" }

Scan → extract → review. Source patching happens in a separate, reviewable phase. → See the Normalize flow

4 model kinds · 27 field types · locale-aware · canonical JSON + Markdown in Git.

Content is plain JSON and Markdown — any language reads it directly. For TypeScript, generate a typed client:

npx contentrain generate

import { query, singleton, dictionary, document } from '#contentrain'

const hero    = singleton('hero').locale('en').get()
const posts   = query('blog-post').locale('en').include('author').all()
const labels  = dictionary('ui-labels').locale('tr').get('auth.login')
const article = document('docs').locale('en').bySlug('getting-started')

contentrain init recognizes 29 stacks, from Nuxt, Next.js, Astro, and SvelteKit to Django, Rails, Laravel, Go, and Flutter. Any language that reads JSON and Markdown can read the content.
