MarsEdit from Red Sweater Software is a desktop blog editor for Mac writers who publish often and want a calmer tool than a browser admin page. Writing a post feels like writing email, drafts live on your Mac, and publishing sends the finished piece to your blog when you are ready.

Key Features

  • Rich text and plain text editing with Markdown syntax highlighting
  • Offline drafts so you can write anywhere and publish later
  • Live preview that shows each post as your site will present it
  • Media handling for images with upload support for common blog systems
  • Micropost panel for short posts you can send with a keyboard shortcut

How to Download

  1. Open the vendor product page and check that your blog platform is supported.
  2. Download from the official site or choose the Mac App Store edition.
  3. Install the app, add your blog account, and pull down your recent posts to begin editing.

System Requirements

The Mac App Store listing for MarsEdit 5.4.7 states that it requires macOS 10.15.4 or later.

FAQs

Which blog platforms does MarsEdit work with?

It supports WordPress and a range of systems that speak standard blog publishing protocols. The vendor site keeps the current list, so confirm your platform there.

Can I write when I have no connection?

Yes. Drafts are stored on your Mac, and you can compose and edit offline. Publishing waits until you are back online and choose to send the post.

Does it support Markdown?

Yes. MarsEdit 5 added Markdown syntax highlighting in the editor, and you can preview the rendered result before the post goes live.
