Read, edit & preview .md files
Only for Mac
$4.99
Mac
mdMD is a fast, native Markdown editor for macOS. More useful than a text editor, more lightweight than an IDE — open a .md file and it just reads beautifully.
WRITE, DON'T FIGHT
Your document renders as you type: headings, bold, lists, tables, and code blocks style themselves in real time. No split-brain preview pane required — though there's a synced split view when you want to see the raw Markdown too.
BUILT FOR SPEED
• Native app — instant launch, tiny footprint, no Electron
• Slash commands: type / for headings, lists, tables, code blocks, and more
• Keyboard-first: ⌘B bold, ⌘I italic, ⌘E inline code, ⌘K links
• Multi-tab editing with session restore
EVERYTHING MARKDOWN
• GitHub-flavored tables with live formatting
• Interactive task lists — click checkboxes right in the editor
• Mermaid diagrams render inline in code blocks
• Syntax-aware code blocks
• Front matter support
SHARE YOUR WORK
• Copy as rich HTML — paste into Notion, Google Docs, or email with formatting intact
• Opens .md, .markdown, .txt, and plain-text config files
• Round-trips file encodings safely (UTF-8, UTF-16, Latin-1)
AT HOME ON YOUR MAC
• Full light and dark mode
• Raw view, styled view, or side-by-side split with synced scrolling
• Drag and drop files to open
• Your last session restores exactly where you left off
No accounts. No subscription. No telemetry. Your files stay yours.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A small release about supporting mdMD.
• Rate or support mdMD from the Help menu. App Store users get a "Rate mdMD" link; free-download users get a link to the Mac App Store page, where buying the app supports development. It's the same app either way — nothing extra to unlock.
• One gentle ask. After you've used mdMD for a while, it asks once — for a rating in the App Store version, or whether you'd like to support the project in the free version. Choose "Don't ask me again" and it never asks again.
