What is MacMD Viewer?
MacMD Viewer is a native macOS app for reading Markdown (.md) files. Built in SwiftUI, weighs just 2 MB on disk, and opens any .md file rendered with full GitHub-flavored Markdown, Mermaid diagrams, syntax highlighting for 190+ languages, and a QuickLook extension so you can preview .md files directly in Finder by pressing Space.
Designed for developers, writers, and researchers who already have an editor (VS Code, Cursor, Obsidian) and just want a fast, clean reader for the Markdown files their AI agents (Claude Code, Cursor, Copilot) keep generating.
Read-only by design — you keep your editor for writing, MacMD for reading. Live file reload means previews refresh ~50ms after the file changes.
$19.99 one-time purchase, no subscription, no account required. macOS 14+, Apple Silicon native.
