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.
- Works with WordPress, Blogger, Tumblr, TypePad, Movable Type and dozens of other systems that support standard MetaWeblog and AtomPub interfaces.
- Work offline with local drafts on your Mac, preview the formatting and content of your posts, and publish when you're ready to share with the world.
- Easily browse for a photo from your iPhoto, Aperture, or Lightroom libraries, and embed it for automatic upload with your blog post.

- 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 10.12 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.

Ratings and Reviews
Makes blog life much easier
I’m a full time writer and have tried numerous apps and methods for writing, editing and posting to the four blogs that I write for. Mars Edit is easily the best I’ve found. For the two larger blogs it makes the editors happy because the HTML formating is always correct unlike any option with Pages, Word or even Evernote. One long-form blog I still write primarily in Pages for it’s outlining capabilities that I use for notes but then paste the final verbiage in MarsEdit, format, add any graphics and post knowing the HTML will be spot on. For one large blog and one of my own I never need to do any other editing directly in Wordpress, just press ‘post’ and it’s done. Two of the blogs, one large, one my own, sometimes require some extra editing of photos but that’s not a problem and still much easier than other options.
Having all of my posts organized in one place is extremely beneficial and makes finding old writing quicker and easier. Also makes cross-posting much easier on the few occasions I’ve done it. All of the editing tools I need are there.
Developer Response ,
Thank you so much for taking the time to write this thoughtful review! I appreciate it. I hope MarsEdit continues to serve you well for all your blogging needs.
Years in the Making
I've relied on two blog editors in over a decade of publishing content to MovableType and WordPress. First was ecto, but it stopped being a viable editor a loooooong time ago. I moved to MarsEdit 3 that looooong time ago, and virtually every blog post I've written for over a decade has been written in MarsEdit.
MarsEdit 4 is a beautiful, simple, efficient upgrade. It carries forth and improves the features every blog owner uses and needs, and enhances others that blog owners didn't THINK they needed but now will. :-) If you're still editing your blog posts in a Web interface, embrace MarsEdit and the power of a full Mac app for your editing. You'll save time, frustration, and energy.
The best got better with version 4.
Astonishingly polished, performant, and fully featured
When I downloaded MarsEdit 4 this morning my jaw hit the floor at the depth and polish of the design improvements the fine folks at Red Sweater have delivered. I was expecting an incremental improvement in the performance and user experience, but this app shows the power of years - more than a decade, in fact - of slow iterative improvements. MarsEdit is a triump of focus on the developer’s part and when people ask me for fine examples of Mac OS development projects I will point first to MarsEdit 4. I cannot recommend it highly enough. 2 million stars, perhaps, would be enough.
