The #1 Blog Editor for the Mac!

MarsEdit is the best way to write, preview, and publish your blog.

Free to download! Unlock a free trial in the app, purchase a full license, or continue to use the app for free to maintain an archive on your Mac and work locally with your published blog posts. MarsEdit 5 can be unlocked at a discounted upgrade price by users who previously unlocked MarsEdit 4.

- Works with WordPress,, Tumblr, TypePad, Movable Type and dozens of other systems that support standard MetaWeblog and AtomPub interfaces.

- Write when and where you want to, with or without an internet connection. Fine-tune your next post on the boat, plane, or train, and publish it when you're back online.

- Browse your Apple Photos, drag images directly, or insert images into your blog post with the click of a button. MarsEdit uploads them all when you're ready to publish.

- Avoid common browser-based problems like losing your edits by navigating to another page, poor spelling for lack of a spell checker, etc.

- Perfect for professional bloggers and casual writers who don't want to mess around with clunky web-based interfaces. If you're lucky enough to have a Mac, nothing is more powerful or more elegant than MarsEdit.

- Write in Rich Text "WYSIWYG" that will be converted automatically to HTML when you publish, or hand-tune the HTML in a syntax-highlighted code editor. Markdown fan? Write in Markdown in the HTML editor and see a live-preview of the HTML rendering in the preview window.

- Compatible with macOS 10.15.4 or higher.

Coming to the Mac from Windows? MarsEdit is similar to Live Writer, the popular Windows blog editor, but differs in some ways. Ask around and read MarsEdit reviews to decide if MarsEdit is right for you.

Even better. Responsive developer. App does it best

If you have a need to blog, especially to wordpress, and if you ever get tempted to use applescript, share sheets, or shortcuts on your mac, don't look to wordpress to help you, but MarsEdit has forever been focused on bringing the creature comforts of your Mac to your wordpress blogging experience.

Over the years (starting since version 1), I've interacted with the developer and he's always been responsive, thoughtful, and open about the product and plans. Even though I don't have the extra features (*ahem* custom posts *wink*) I'd like to see, this is definitely put together by a developer that wants the experience of blogging to be mac native and work well! And the app delivers 100% -- Version 5 is excellent. so much so that I have it here on the app store and through setapp

SO looking forward to becomig more proficient with MarsEdit

As a long time dead Windows Live Writer (currently Open Live Writer) user, I've been hoping to find something to replace them order to abandon Windows fully and stick with MacOS (hopefully iOS iPad someday?). Having a responsive developer with deep roots in the Apple world constantly debugging and improving gives me hope. Although I'm just a week or so into using MarsEdit, it is almost exactly what I've been looking for ... add the ability to upload photos, video and PDF files to a separate image server ... be it publicly accessible cloud-based (ie. AWS S3, etc) or a SFTP low-cost server ... and I'll never look back. 😉

Indespensible for bloggers

If you have a blog, you need this app. I use it to write and review my writing in a different way to catch typos and code issues. I crank the type-size up and use Georgia so I can read what I wrote. And I use it to create local copies of my posts in case WordPress effs them up somehow. I even use it to write HTML emails via code. Plus, the developer is very responsive to solve problems (though, there are few). Just buy it already.

Thanks for the kind words and positive review!
