Stop guessing which one. Put them side by side.

The grid says what these tools are. This says what builders did about it — one decision per person, changeable whenever you change your mind.

# Tool comparison — Hygraph vs Keystatic vs MDX

Source: Kbaise, a directory of tools that work with Lovable projects.
Pick one and tell me why before writing any integration code.

## Hygraph (hygraph)
- URL: https://hygraph.com
- Category: CMS & content infrastructure
- Cost: mixed — Hobby free: 3 seats, 1,000 entries, 500k API operations/mo, 2 locales. Growth $199/mo (10 seats, 10k entries, 1M ops, 3 locales). Enterprise custom.
- What it is: Hygraph is a GraphQL-native headless CMS whose distinguishing feature is content federation — remote REST or GraphQL sources are stitched into one schema, so a single query returns CMS content alongside data from other systems.
- Why builders pick it: Right choice when the publication pulls from external systems — commerce, ticketing, a legacy archive — and you want one query instead of an orchestration layer. MCP server entered early access in January 2026.
- Trap: The free tier's 1,000-entry cap is small for any real content archive, and the step up to Growth is $199/mo. Everything is GraphQL with no REST fallback.
- Wiring: npm i graphql-request

## Keystatic (keystatic)
- URL: https://keystatic.com
- Category: CMS & content infrastructure
- Cost: free — Free and MIT-licensed with no seat limits. Keystatic Cloud is an optional free add-on for GitHub auth and image handling.
- What it is: Keystatic from Thinkmill is an MIT-licensed CMS that makes Markdown, MDX, JSON and YAML in your repository editable through a React admin UI. There is no database. It runs against the local filesystem in development and against GitHub in production.
- Why builders pick it: Zero cost and zero vendor lock-in — the schema is a TypeScript file and content stays as plain files you can grep and diff. Ships integrations for Next.js, Astro and Remix.
- Trap: Smaller community and slower release cadence than Tina or Payload. No official MCP server, no built-in scheduling, and no multi-stage editorial workflow or approval chain.
- Wiring: npm create @keystatic@latest
- Full dossier: /api/public/tools/keystatic

## MDX (mdx)
- URL: https://mdxjs.com
- Category: CMS & content infrastructure
- Cost: free — Free, MIT-licensed open format.
- What it is: MDX is a format that lets you write JSX inside Markdown, so an article can embed live React components — charts, interactive figures, embeds — between paragraphs of prose. It compiles to a React component and is supported by Vite, Next.js and Astro.
- Why builders pick it: The reason a technical publication can ship an interactive explainer inside an ordinary article. Every file-based tool here — Tina, Keystatic, Outstatic, Velite — speaks it natively.
- Trap: MDX is a compiler, not a CMS: no editor, no media library, no workflow, no roles. Non-technical writers will not author raw MDX, so pair it with an editing layer.
- Wiring: npm i @mdx-js/rollup

## Quick read

- Free with no card: Keystatic, MDX.

## Rules
1. Prefer the free tier when no budget was stated, and say what the ceiling is.
2. Read the full dossier before integrating.
3. Fetch /api/public/models before writing any AI model ID.

Agents can fetch the same thing: GET /api/public/compare?slugs=hygraph,keystatic,mdx
