Where MacMD Viewer May Have an Edge
QuickLook depth. MacMD Viewer markets itself as having the most feature-complete QuickLook extension for Markdown on Mac. Both apps support Mermaid in QuickLook, but MacMD Viewer may render additional elements in the QuickLook preview that others don’t. If QuickLook is your primary use case, it’s worth testing both.
Marketing and documentation. MacMD Viewer has a well-structured website with blog posts, feature pages, and guides. Their marketing is polished. If you’re evaluating tools for a team, their documentation may help with the decision.
Where MDViewer Wins
Price (right now). MDViewer is currently free for early adopters — all features included. A Pro tier is planned, but early users get the full app at no cost. MacMD Viewer costs $19.99 as a one-time purchase.
Inline editing. MDViewer lets you edit Markdown in the same app. Double-click a word, make changes, Cmd+S to save. MacMD Viewer is a viewer only — you need a separate editor.
Git history and diffs. MDViewer shows the full Git commit history of any .md file with color-coded diffs between versions. This is essential for developers reviewing documentation changes. MacMD Viewer doesn’t offer Git integration.
JSON and Mermaid QuickLook. MDViewer’s QuickLook extension handles .md, .json, and .mermaid files — not just Markdown.
KaTeX math rendering. MDViewer renders inline and display LaTeX math formulas. This matters for technical and academic documentation.
Proven track record. MDViewer has been available and actively updated. Check the changelog for version history and feature releases.
Who Should Choose MacMD Viewer
- Users who primarily want QuickLook preview and value MacMD’s deeper QuickLook integration
- People who prefer paying for software to support indie development
- Users who don’t need editing or Git history
Who Should Choose MDViewer
- Developers who work with Git repos and want file history + diffs
- Anyone who wants viewing and editing in one app
- Users who also preview .json and .mermaid files via QuickLook
- People who want a full-featured Markdown viewer at no cost right now
- Teams where “install this free app” is easier than justifying $19.99 per seat
The Bottom Line
MDViewer and MacMD Viewer are both solid native Markdown viewers for macOS. The core Markdown rendering experience is similar. The difference is that MDViewer adds inline editing and Git history, while MacMD Viewer focuses on QuickLook depth.
