OpenMark vs Mark Text

Which markdown editor is right for you?

Mark Text was a popular free, open-source Markdown editor with inline WYSIWYG rendering. But the original developer has moved on, and the project is effectively abandoned — the last stable release was in 2022. OpenMark is actively developed for macOS Tahoe with native performance and modern features.
