## What is Frontmatter?

Frontmatter is a suite of build-time tools for Astro developers.
It bridges the gap between Astro frontends and server-side backends — PHP, Symfony, Drupal, WordPress — without runtime dependencies.

## Products

### Frontmatter Core
- URL: https://frontmatter.tech/core
- License: MIT (open source)
- Description: A build-time content layer engine for Astro. Scans .astro, .md, and .yaml files and outputs a stable typed JSON Intermediate Representation (IR) that CMS adapters and paid tools consume.
- GitHub: https://github.com/withfrontmatter/frontmatter-core

### Frontmatter Solo
- URL: https://frontmatter.tech/solo
- Price: $49 one-time
- Description: Reads an Astro project at build time and generates a complete server-side render pack — Twig or plain PHP templates, layouts, partials, a manifest.json, and an INTEGRATION.md. No rewrite. No runtime. No coupling.
- Output formats: Twig (Symfony, Drupal, Craft), plain PHP includes (WordPress, custom CMS)
- Delivery: CLI (macOS, Linux, Windows via Node) + Desktop app (macOS, built with Tauri)
- Stack pages:
  - WordPress: https://frontmatter.tech/solo/wordpress
  - Symfony: https://frontmatter.tech/solo/symfony
  - Twig: https://frontmatter.tech/solo/twig

### Frontmatter Studio
- URL: https://frontmatter.tech/studio
- Status: Coming soon
- Description: From Astro to a fully editable site with Grav CMS wired in. No backend developer required.

## Key concepts

- Build-time only: Frontmatter tools run at build time and produce static file outputs. No runtime dependency is added to the project.
- Props → variables: Astro component Props interfaces map directly to template variables (Twig: {{ var }}, PHP: $array['var']).
- Render pack: The output of Frontmatter Solo — a self-contained folder of templates, manifest, and documentation that a backend developer can use immediately.
- IR (Intermediate Representation): A stable typed JSON structure output by Frontmatter Core. Used as the contract between the Astro frontend and any backend or CMS.
