Markoff 
A light-weight CommonMark previewer for OSX.
- Uses
cmark, a C implementation of CommonMark, for parsing and rendering. This is a lot of faster than other existing Ruby and JavaScript solutions. - Allows you to select your default editor and open the previewed document in it
by hitting
Cmd+e, using the menu item, or clicking the toolbar button. - Uses highlight.js for syntax highlighting.
- Detects YAML frontmatter and renders it as a special code block.
- 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 information such word and character count.
