Frontmatter Core

Hey, I’m Alexandre, the creator of Frontmatter Core. I built this because modern frontends (Astro, Markdown, file-based content) and real CMS systems don’t speak the same language. Frontmatter Core is a build-time data layer that scans your Astro, Markdown and YAML, and turns them into a typed JSON Intermediate Representation that real CMS adapters can consume. No runtime. No lock-in. Just clean content models generated from your codebase. This is just the core — adapters and tooling will be built on top of it. I’d love your feedback, especially if you’ve ever tried to connect a static site to a real CMS without losing control of your content model.
