Everything you need to write about MacMD Viewer. App details, media assets, and contact information.
MacMD Viewer is a native macOS application for rendering Markdown files with Mermaid diagram support, syntax highlighting, and QuickLook integration.
MacMD Viewer is a lightweight, native macOS app built with SwiftUI for one purpose: rendering Markdown files beautifully. At just 2 MB, it launches instantly and runs with minimal system resources — a sharp contrast to Electron-based alternatives that ship at 200 MB or more.
The app includes a QuickLook extension that lets users press Space on any .md file in Finder to see it fully rendered with headings, code blocks, tables, and diagrams. It supports Mermaid diagrams natively (flowcharts, sequence diagrams, Gantt charts, and more), provides syntax highlighting for over 100 programming languages, and features live reload so edits made in any external editor appear instantly.
MacMD Viewer is a one-time purchase at $19.99 with no subscription, no account required, and no tracking. It is built by Arthur, an indie developer focused on making tools that do one thing well.
MacMD Viewer is 2 MB. Electron-based alternatives are 200 MB or more. It launches instantly, uses minimal memory, and feels like a first-party Apple app.
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.
Press Space on any .md file in Finder to see it fully rendered. No other markdown app offers this level of system integration.
Flowcharts, sequence diagrams, state machines, and more render natively. No plugins, no configuration, no external dependencies.
