MarkEdit is a free and open-source Markdown editor, for macOS. It's just like TextEdit on Mac but dedicated to Markdown.

• Privacy-focused: doesn't collect any user data
• Native: clean and intuitive, feels right at home on Mac
• Fast: edits 10 MB files easily
• Lightweight: installer size is about 3 MB
• Extensible: seamless Shortcuts integration

MarkEdit is designed to be simple and easy to use. You can also customize the UI and behavior by adding your own scripts, including utilizing CodeMirror extensions.

To learn more, refer to Philosophy, Why MarkEdit and MarkEdit-api.

Get MarkEdit.dmg from the latest release, open it, and drag MarkEdit.app to Applications.

MarkEdit checks for updates automatically. You can also check manually via the main MarkEdit menu, or browse version history here.

If you prefer a Homebrew installation, run brew install markedit in your terminal and you're all set.

We used to publish MarkEdit to the Mac App Store, but no longer. Don't worry about the security warning; releases are signed with a certificate from an identified developer and notarized.

To be focused, we only support the latest two major macOS releases. For now, they are macOS Sonoma and macOS Sequoia.

Last-compatible version tags: macos-12, macos-13.

MarkEdit is completely free and open-source, with no advertising or promotions for other services. We make it mostly because we need it, and we ship it just in case you need it too.

MarkEdit is built on top of the awesome CodeMirror 6 project.

MarkEdit uses ts-gyb to generate lots of boilerplate code.
