Show HN: Astro Editor – Free macOS Markdown editor for Astro content collections
dannysmith Wednesday, November 26, 2025Hey HN, I built this because I wanted to write more on my personal website but found VS Code et al terrible for prose.
Astro is a great static site framework for content-heavy sites, but its content files use MDX (markdown + JSX components) with YAML frontmatter. Regular markdown editors like iA Writer can't handle this properly.
Astro Editor is basically iA Writer for Astro content collections:
- Distraction-free writing with focus mode (hides YAML and imports)
- Auto-generates frontmatter forms from your Zod schemas
- Component insertion with prop picker for MDX
- Drag-and-drop image handling
It's free and open source, built with Tauri + React.

Happy to answer any questions, obvs.
