Everything you need to write about MacMD Viewer. App details, media assets, and contact information.
One-liner
MacMD Viewer is a native macOS application for rendering Markdown files with Mermaid diagram support, syntax highlighting, PDF export, and Quick Look integration.
Boilerplate
MacMD Viewer is a lightweight, native macOS app built with SwiftUI for one purpose: reading the markdown your AI agents and LLMs write. It is a 5.4 MB download, a native app rather than a web or Electron wrapper (see how it compares). The current version is 1.7.0, released October 10, 2026.
The app includes a Quick Look extension that lets users press Space on any .md file in Finder to see it fully rendered with headings, code blocks, tables, and Mermaid diagrams. It highlights code blocks, reloads live when an editor or coding agent saves the file, and exports a document to PDF with its diagrams and highlighted code. Version 1.7.0 adds Copy as Markdown, Open in your editor, and a word count with reading time.
MacMD Viewer is a one-time purchase at $19.99 with no subscription and no account required; documents never leave the Mac. It is built by Arthur, an indie developer focused on making tools that do one thing well.

What makes it different
Native SwiftUI (not Electron)
MacMD Viewer is a 5.4 MB download and 16 MB installed. It's a native macOS app with no bundled Chromium: not a web app, not Electron.
Read-only viewer (not an editor)
Most markdown apps try to be editors. MacMD Viewer does one thing perfectly: render markdown files. Use whatever editor you prefer, VS Code, Vim, Zed, and let MacMD Viewer handle the reading.
QuickLook extension
Press Space on any .md file in Finder to see it fully rendered, Mermaid diagrams included, without opening the app.
Mermaid diagrams built-in
Mermaid code fences render in the app, in Quick Look and in PDF exports. No plugins, no configuration, and it works offline.
