MarsEdit 5 - Powerful web publishing from your Mac.:

Browser-based interfaces are slow, clumsy, and require you to be online just to use them. Web browsers are wonderful for reading articles, but not for creating them. If you're writing for the web, you need a desktop blog editor. And if you're lucky enough to have a Mac, nothing is more powerful, or more elegant than MarsEdit.

Marsedit is such a great app for interacting with weblogs. On every other platform I’ve touched - Windows, Linux, even iOS and iPadOS - I have searched for something similar, or even close, and fallen short.

My only wish in relation to this is that there was an iOS/iPadOS version so I can keep up my workflow across my more personal devices. It would be an insta-buy for me, and I’m sure many others.
