MarkEdit is a free, open-source native macOS Markdown editor built with Swift and CodeMirror 6, designed to feel like TextEdit but dedicated to Markdown. It emphasizes a tiny ~4 MB size, fast handling of very large files, strict GFM correctness, and extensibility via CSS, JavaScript, and CodeMirror extensions.

Use cases

• edit markdown files on mac
• lightweight markdown editor for macos
• open large markdown files quickly
• write documentation in markdown natively on mac
• markdown editor with preview pane
• customize markdown editor with css and extensions
• privacy-focused markdown writing app

When to choose

• you want a native, fast, lightweight Markdown editor on macOS
• you need to edit very large Markdown files without lag
• you value GFM spec correctness and native Mac integration like Shortcuts and AppleScript
• you want an extensible editor with themes, preview, and AI writing extensions

When to avoid

• you need a cross-platform editor for Windows or Linux
• you want a full IDE or rich WYSIWYG word processor
• you require macOS 15 or earlier compatibility, since it targets macOS 15.0+
