Keystatic

MIT Git-based CMS for Markdown files

FreeCMS & content infrastructurekeystatic.com

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 it earns a slot

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.

Know before you commit

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.

Getting started
