Markoff 2 Platform Platform

A lightweight CommonMark previewer for macOS Big Sur and later.

  • Uses SwiftDoc's CommonMark implementation for transforming the markdown into HTML.
  • Uses the Composable Architecture.
  • Uses the new SwiftUI lifecycle for document-based apps.
  • Auto-reloads the preview whenever the original file is saved. Depending on your editor, you might be able to set up auto-save to get an always up-to-date preview without manually saving.
  • Shows basic metadata such word and character count.

Left to Do for 2.0

  • Code syntax highlighting.
  • Select default editor.
  • Add printing support.
  • Add addtional CSS styles.


  1. Open the project in Xcode 12 or later.

If you use another text editor, follow your usual SPM workflow.
