Zero trackingYour words stay yours
Intentionally simple
Everything you need.
Nothing you don’t.
Like TextEdit, but dedicated to Markdown.
Thoughtful details, without a whole new workflow to learn.
Lightweight. Not light-duty.
Multi-caret editing, code folding, and large files handled with ease. A small app with a capable editing engine, built on CodeMirror 6.
Plain text. Plain and simple.
Standard Markdown, not a proprietary format. MarkEdit follows GitHub Flavored Markdown and collects no user data. Your documents are your business.
A space that feels like you
Your words.
Your way.
A quiet light theme for the morning. Something darker for a late-night idea. Find your favorite colors, choose your font, and settle in.
Find your theme
Small at heart. Room to grow.
A little more,
when you want it.
Add View Modes for previews and syntax-hidden editing, Vim keybindings, or a favorite theme. Discover extensions in the app, and make MarkEdit fit the way you work.
Explore extensionsMade with care. Shared freely.
Good tools are
better when shared.
MarkEdit is a tool we use every day and keep improving for ourselves. We share it openly, hoping it makes a little room for your ideas, too.
Meet the project on GitHubA few good questions
Before your first draft.
Is MarkEdit really free?
Yes. MarkEdit is free and open source, released under the MIT License. There is no paid tier to unlock. You can read the code, report a bug, or contribute on GitHub.
Will it work on my Mac?
The current release requires macOS 26 or later. For Macs running macOS 12 through 15, you can find compatible releases in the installation guide.
Can I preview Markdown or hide its syntax?
Yes. Install the optional View Modes extension to switch between Markdown source editing, side-by-side or overlay previews, and Mixed mode, which hides Markdown syntax while you edit. Choose a mode from Extensions > View Mode. The core app stays focused on editing; you choose the extras.
