I built this because most Markdown previews are either inside editors, browser-based, or tied to heavier tools.

Sometimes you just want to double-click a .md file and read it like a document.

MDviewer is a tiny native macOS app that opens Markdown files as print-ready pages with good typography. You can also print or export directly to PDF.

Features:native macOS (Cocoa + WKWebView), double-click Markdown files from Finder, no Electron, no cloud or telemetry, safe rendering (marked + DOMPurify + strict CSP)

Curious if people would use a dedicated Markdown reader like this or if editors already cover the use case.
