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
