MarkdownBlaze

MarkdownBlaze is a fast, no-fuss viewer for Markdown (.md) files. Point it at
a document, or at a whole folder, and it renders a clean, readable page in a
moment, then gets out of your way.

It is also the rare Markdown viewer that prints properly. Choose from eleven
document themes, switch to page view to see the document laid out on A4 sheets
exactly as it will print, and pick the look for each print from a bar along
the bottom of the window. Only the document is printed, never the app around
it.

It understands the Markdown you actually use: tables and task lists,
footnotes, code with syntax highlighting for about 190 languages, Mermaid
diagrams, KaTeX math, callouts, and Obsidian wiki links, tags and comments.

The sidebar shows the folder you are reading as collapsible panels, with the
outline of the current document. Links between Markdown files open inside the
app, and the view refreshes when you save the file in your editor.

MarkdownBlaze makes no network requests of its own and has no accounts, ads
or tracking. The only time anything goes online is when a document you open
references a resource on the web, such as a remote image.

Files on removable media (USB drives) are reachable once you run:
