Frontmatter

Open-source tools to turn developer-authored content into CMS-ready data.

We build:

  • Frontmatter Core — the build-time data layer for Astro, Markdown, YAML
  • CMS adapters
  • Tooling and examples

We believe:

  • content should be portable
  • schemas should emerge from usage
  • CMS should consume data, not control design
