MarsEdit vs Ulysses vs iA Writer: Best Mac Blogging Software in 2026

Mac users have always had better writing software than everyone else. That’s not bias — it’s history. The blogging software ecosystem on macOS stretches back to 2002, when tools like iBlog, Ecto, and Kung-Log were letting Mac users publish to the web before most people knew what RSS was.

In 2026, the field has narrowed to a handful of genuinely excellent options. We tested the three most-recommended ones — MarsEdit, Ulysses, and iA Writer — over several weeks of real publishing to WordPress, Ghost, and Micro.blog. Here’s exactly what we found.

Quick Comparison Table

MarsEdit 5 — The Dedicated Blogger’s Tool

MarsEdit has been the gold standard for Mac blogging clients for over two decades. Version 5, released in 2023, brought a modernized interface, improved media handling, and full Apple Silicon support while keeping everything that made the app great in the first place.

The core proposition is simple: write in a desktop editor, preview exactly as it will look on your site, publish with one click. No browser tab. No web interface lag. No accidentally closing a tab and losing your draft.

What MarsEdit Does Exceptionally Well

Direct publishing integration is where MarsEdit pulls away from every competitor. It works with WordPress, Micro.blog, Tumblr, TypePad, Movable Type, and dozens of other systems that support standard MetaWeblog and AtomPub protocols. Setup takes about 90 seconds — enter your WordPress URL, authenticate, done. Your entire post history is accessible in the sidebar immediately.

The preview engine renders your post using your actual site’s CSS. Not a generic preview — your exact theme, your exact fonts, your exact spacing. You know exactly what readers will see before you hit publish. No other app in this test matches this feature.

Performance is where MarsEdit genuinely stands apart. On Apple Silicon, MarsEdit launches in under two seconds and handles the full editing workflow — including rich text, media management, and live preview — without lag. We ran it alongside Ulysses and iA Writer for four weeks. MarsEdit was consistently the fastest app to open, fastest to load post history, and most stable under heavy use.

The pricing model deserves specific mention. At $59.95 as a one-time purchase, MarsEdit costs less in year one than Ulysses does, and nothing in year two, three, and four. For a tool you’ll use daily for years, the math is straightforward.

Where MarsEdit Falls Short

The interface is functional rather than beautiful. Compared to Ulysses’ refined design, MarsEdit looks like a professional tool — which it is — but not a design showcase. If you care deeply about the aesthetics of your writing environment, Ulysses wins on first impression.

There is no iOS app. If you write on iPhone or iPad as well as Mac, MarsEdit covers only half your workflow. This is the single biggest reason to consider Ulysses instead.

Major version upgrades require separate purchases, which can create uncertainty about long-term costs — though in practice, Red Sweater has been generous with upgrade pricing historically.

MarsEdit Score Breakdown

Ulysses — The Writer’s Operating System

Ulysses is not a blogging client. It is a writing environment that happens to support publishing to blogs. That distinction matters and determines whether it belongs in your workflow at all.

Where MarsEdit thinks in terms of posts, Ulysses thinks in terms of a writing library. Every piece you write lives in one organized system — essays, drafts, published posts, research notes, long-form projects — all searchable, all synced across Mac, iPad, and iPhone via iCloud. It is the closest thing to a writer’s operating system that exists on Mac today.

What Ulysses Does Exceptionally Well

The writing experience is Ulysses’ defining strength. The interface is beautiful, distraction-free, and deeply considered. Markdown is first-class. The typography is excellent. Writing in Ulysses feels like using a tool that respects the act of writing, which sounds subjective until you experience the difference firsthand.

Cross-device sync via iCloud is seamless. One subscription covers Mac, iPhone, and iPad, and Apple Family Sharing extends a single subscription to up to six family members. If you write on the go, Ulysses is the only app in this test that covers the full Apple device stack in one purchase.

Export flexibility is exceptional. Export formats include PDF, DOCX, HTML, ePub, and more, with a dedicated styles and themes ecosystem for customizing export appearance — plus direct publishing integrations for WordPress and Ghost. Your work is never trapped in a proprietary format.

Where Ulysses Falls Short

The subscription model is the elephant in the room. The annual plan runs $39.99 per year — saving around 30 percent compared to the $5.99 monthly plan. Over four years that’s $160 versus MarsEdit’s $59.95 one-time fee. Compared to Scrivener’s one-time $60 purchase, Ulysses looks expensive over a multi-year horizon.

If you stop paying, Ulysses enters read-only mode. Your writing is not deleted, but you cannot edit it. This “renting your writing tool” dynamic is a real concern for anyone planning long-term use.

For pure blogging workflows, Ulysses is also more complex than necessary. Its organizational system — Sheets, Groups, Filters — is powerful but takes time to learn. MarsEdit is ready to publish on day one.

iA Writer — Pure Focus, Zero Distractions

iA Writer is the most opinionated writing tool in this comparison. It does one thing: get you writing in Markdown with zero distractions, and it is better at that one thing than any app on the market.

There are no tags. No folders beyond the file system. No blogging integrations beyond WordPress via export. iA Writer is a text editor built by designers who believe the interface should disappear and leave only you and your words.

What iA Writer Does Exceptionally Well

Focus Mode highlights the sentence or paragraph you are currently writing and dims everything else. It sounds like a gimmick. In practice, it changes how you write. The app has won multiple design awards and the interface holds up — this is design at the level of consideration that most apps never reach.

The pricing is the best of the three for writers who work primarily on Mac. $49.99 as a one-time purchase gets you a genuinely excellent writing environment. No subscription. No upgrade anxiety. The iOS app is a separate purchase but remains reasonable.

File-based storage means your writing lives in plain Markdown files on your Mac. Open them in any editor. Move them anywhere. iA Writer creates zero lock-in — your content is yours in the most literal sense possible.

Where iA Writer Falls Short

For bloggers specifically, iA Writer’s publishing workflow is the weakest of the three. There is no native WordPress integration that lets you publish directly. You write, export, then paste into WordPress manually — or use a plugin to bridge the gap. It works but it is an extra step every single time.

The organizational system is minimal by design. If you manage hundreds of posts and drafts, the lack of tags, smart folders, and library organization becomes a real friction point over time.

Head-to-Head: Which One Is Actually For You?

Our Verdict

MarsEdit wins for bloggers. It is the most focused, most capable, most Mac-native tool for the specific job of writing and publishing posts to a blog. The one-time pricing is genuinely fair. The publishing integration is unmatched. The performance is exceptional.

Ulysses wins for writers who blog rather than bloggers who write. If your primary identity is writer — novelist, essayist, journalist — and your blog is one output among many, Ulysses’ library organization and cross-device sync are worth the subscription cost.

iA Writer wins for minimalists who want to own their tools outright and never think about pricing again. It is the most honest tool of the three — it does exactly what it says and nothing more.

All three are excellent. None of them will let you down. The right choice depends entirely on how you work, not on which app has the most features.
