Markdown Better View vs MDViewer
Two native Mac Markdown viewers — similar goals, different trade-offs
Quick Overview
Markdown Better View is a Mac App Store viewer released in June 2026. It renders Markdown with Mermaid diagrams, KaTeX math, and syntax highlighting. It provides both QuickLook previews and Finder thumbnails for .md files. It requires macOS 15 (Sequoia) and costs $9.99 after a 14-day trial.
MDViewer is a native SwiftUI viewer with inline editing, Git history and diffs, a scroll-tracking table of contents, and tabs. It runs on macOS 13.0 and later. The Lite tier is free; Pro costs $9.99 one-time.
Both apps occupy the same niche — dedicated Markdown viewers for macOS — but differ in OS compatibility, editing, Git features, and distribution model.

When to Choose Markdown Better View
- You prefer installing from the Mac App Store with automatic updates and sandboxing
- You want Finder thumbnails that show rendered previews of
.mdfiles in icon and gallery views - You want multiple visual themes (5 built-in options)
- You are already on macOS 15 and the OS requirement is not a concern
- You want the smallest possible app on disk (~4.8 MB)
The macOS Compatibility Question
This is the biggest practical difference between the two apps. Markdown Better View requires macOS 15 (Sequoia), released in late 2024. If your Mac runs macOS 13 (Ventura) or macOS 14 (Sonoma), you simply cannot install it.
MDViewer supports macOS 13.0 and later, covering three major OS versions. This matters if you have older hardware, if your organization delays OS upgrades, or if you prefer to stay one version behind for stability.
If you are already on macOS 15, this difference does not affect you. But for teams with mixed OS versions, only MDViewer works across all of them.
Editing and Git: The Feature Gap
Markdown Better View is strictly a viewer. You open a file, read it, and close it. If you need to fix a typo, you switch to another app.
MDViewer Pro adds two features that blur the line between viewing and lightweight editing:
- Inline editing: Double-click any section to switch to source mode. Make your change, and the rendered view updates. This is not a full editor — it is designed for quick fixes without context-switching.
- Git history: For any Markdown file in a Git repository, MDViewer shows the full commit history in the sidebar. Click a commit to see a color-coded diff of what changed. This is valuable for documentation maintained in Git — you can trace when a section was added or modified without opening a terminal.
If you never edit Markdown files and do not use Git, these features do not matter. If you do, they save meaningful time.
