## What it is
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+
