ContentfulKeystaticMDX
Quick read
- Free with no card: Keystatic, MDX.
| Field | Contentfulcontentful.com | Keystatickeystatic.com | MDXmdxjs.com |
|---|---|---|---|
| What it is | Contentful is a hosted API-first CMS with structured content modeling, a web editor, GraphQL and REST delivery APIs, and multi-environment workflows. The free plan covers 10 users, 10,000 records, 100,000 API calls per month, 2 locales and 25 content types. | 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. | 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. |
| Category | CMS & content infrastructure | CMS & content infrastructure | CMS & content infrastructure |
| Cost tier | mixed | free | free |
| Pricing | Free: 10 users, 10k records, 100k API calls/mo, 2 locales, 25 content types. Lite $300/mo (20 users, 1M calls, 3 locales). Enterprise custom. | Free and MIT-licensed with no seat limits. Keystatic Cloud is an optional free add-on for GitHub auth and image handling. | Free, MIT-licensed open format. |
| Why builders pick it | The safe enterprise choice when procurement, SSO, audit logs and SLAs matter more than price. Mature localization and a large app ecosystem make it defensible for a multi-brand publisher. | 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. | 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. |
| Watch out for | The jump from free to Lite is $300/mo with nothing in between, and only 2 locales are free. Personalization, AI Actions and Studio all require Enterprise. MCP support is community-maintained, not official. | 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. | 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. |
| How to wire it up | npm i contentful | npm create @keystatic@latest | npm i @mdx-js/rollup |
| Editor's pick | No | No | No |
