MarsEdit 4 for Mac download

Quick overview

MarsEdit 4 from Red Sweater Software is a desktop blog editor that lets authors draft, edit, and publish posts without opening a web browser. It works with many popular blogging services — for example WordPress, Tumblr and Blogger — and is designed to let you manage several blogs from a single application, even when those blogs are hosted on different platforms. Offline editing is supported, so you can work without an internet connection and publish later.

Connecting to your blogs

To link a blog to MarsEdit you usually provide the blog’s URL and then sign in with the account credentials for that platform. Once connected, the app can retrieve your existing posts and archives. New entries can be previewed before they go live, and uploading/publishing is handled directly from the desktop client.

Writing and formatting tools

Offline drafting and the ability to handle multiple blogs from one place
Built-in spell checking to catch typos while you write
Support for HTML and other markup formats (advanced editing options for authors comfortable with code)
Post previewing and one-click publishing/updating of entries
Access to a full archive of previously published posts for quick edits or reposting

Note: the formatting toolbar is geared mainly toward HTML and rich text; it doesn’t expose controls for every possible markup workflow, which may frustrate users expecting broader toolbar options.

Known limitations

The app can have trouble with platforms that require complex, multi-step authentication flows; certain modern two-factor or token-based systems may not integrate smoothly.
For someone who only needs to maintain a single, very simple personal blog, MarsEdit’s feature set may feel like overkill.

Alternatives and paid solutions

Commercial authoring suites and paid blogging tools are available if you want more specialized writing features or integrated team workflows.
Minecraft: Java & Bedrock Edition was listed as a suggested alternative in the original source (not directly comparable as a blogging tool, but noted there).

Recommendation

Overall, MarsEdit 4 is a feature-rich, well-designed desktop blog editor with a clean interface and robust capabilities. Despite occasional authentication hiccups and a toolbar focused on HTML/rich text, it remains one of the stronger options for authors who write across multiple platforms or prefer offline desktop editing.
