MarsDawn

Eight looks, one export.

MarsDawn ships four preview themes, Dawn, Classic, Modern and Vivid, each with a light and a dark palette — eight combinations to read a document in. Export to PDF or print, and the page comes out in whichever one you were reading.

Four themes × light and dark = eight ways to read a document, and one export path that matches whichever you chose. More importable themes, and a gallery to share your own, are planned — not built yet.

The four themes

Each one has its own light and dark variant, so switching your Mac's appearance switches the theme's palette with it, not just the interface chrome.

PDF export and print use the same theme

Export to PDF or print, and the page uses your theme's light palette: Mermaid diagrams are drawn into it, code blocks keep their syntax highlighting, and page breaks avoid splitting a heading from its section or cutting a table or diagram in half. The free marsdawn command-line tool uses the same exporter, so a script or an agent produces the identical PDF, in any of the four themes, with --theme.

Planned: more themes, and a gallery

Coming later, not shipped yet: more importable preview themes, and a gallery on this site where people can submit their own. /themes/v1/ is already reserved for it. Until that ships, the four built-in themes are what MarsDawn has, and you can't install others.
